Question regarding cell info on PPC

ON old Nokia phones and the like, they would show you the name of the transmitter that they were currently hooked up to, it would usually be the location of the transmitter that was the name.
It would change as you travelled through different areas and was interesting to know which transmitter you were hooked up to.
Is there any way to display the transmitter name on Windows Mobile somehow? I've tried searching but come up blank.
Thanks.

I use Phonealarm, and the skin configuration that I use has an add-on feature where it will scroll different info such as; battery level,operator,data usage as well as cell info. With the cell info you can actaully create groups;home, work,mother-in-laws or whatever you feel like calling them. Did your Nokia give a name or a numerical description?

cell info, thats the one..it gave the name of the actual transmitter location.

if you find something similar in WM5, please let me know, thanks

I've done a lot of searching on Google, but it seems it must not be possible.

GNSS Internet Radio and Built in GPS

Hello,
I am new to the forum and also the owner of an HTC Fuze. I have been playing around recently with the GPS on the phone and got me thinking. I live in NY and we have a CORS network of gps base stations that are fed by the use of ntrip.
I was wondering if their was any way to use the gps signal on my phone and the connection to this CORS network to give me sub inch accuracy on my phone...then not sure what I would do with it then. But I do live on a farm and I would like to see some type of precision agricultural use.
I guess I need a way to have the GPS on the phone talk with the GNSS internet radio and then give me spot on guidance and such.
Please let me know your thoughts or if I need to explain better.
Thanks,
Clayton

bump
bump. Any ideas? Anyone

Great idea cwrisrey !
That will save the cost of a geodetic device, which is many times the cost of a Fuze. Further, it will lead the accuracy of the buildin GPS into millimum class.
Not dig into this further, would you go further to tell these:
Is that CORS data encrypted?
Is that accessible through public internet or VPN?
Is there copy right or intellectuall property right issue involved? (I don't think so, but better make it clear first)
Once again, great idea. Please do remember to update this thread once you got any progress. Thanks.

Hello wg5566,
This site would probably answer alot of your questions clearer than I could:
http://www6.nysdot.gov/spiderweb/frmIndex.aspx
* Is that CORS data encrypted?
-I don't believe so, I think that it is just a form of compression, to distribute across the internet.
* Is that accessible through public internet or VPN?
Yes, the NYS CORS anyway. It accessible from the public internet (although they require you to register with them) But I believe there are other free streams. I also believe it was modeled after being able to be sent threw GPRS.
* Is there copy right or intellectuall property right issue involved? (I don't think so, but better make it clear first)
-I believe the ntrip is based on a GNU, I think the source code is available. http://igs.bkg.bund.de/index_ntrip_down.htm
Windows CE version:
http://www.ilmb.gov.bc.ca/crgb/gsr/downloads/installGNSS.CAB
Please, let me know your thoughts...
Thanks,
Clayton

My fast thoughts:
First make sure there is no satisfied freeware currently available for WM.
If so please ask a moderator to move this to the development & hackings section. And Add tyis sentence on the title: Call for developers for revolutionary GPS app!
I'm sure somebody here can develop this. You know the geodetic device was invented many years ago with very weak profiles comparing to current WM devices. The hardware on our phone should be capable to deal with these calculations, and the WM Pro platform should be capable to support such an app. Anyway it should not be a biggy for many masters here. But it is a biggy for gps users with high accuracy demand for any reason.
Edit: Did you try install that wince cab on your phone? I think some of WINCE apps can just run on WM. Please backup your data first.
Edit2: I tried to install it on my device, at first it did not show up in start menu, then I found the cab just put files and shortcut in the folder names in French. But there is no registry involved in the cab. Only three files. And then program UI itself is in English. Just run the executable from the folder will go right out of the box. So please try it. I did not try to connect & loggin yet, due to not registered account.
Edit3: Looks like the cab is only access the data from internet, convert the data format and export the data, but we still need a geodetic/gps software to process/use the data.
Disclaimer: I attatched these three files for the only purppose of exchanging software developement infomation. Anybody if download it please do not use it for any purppose other than this. Thanx.

Some thoughts on the subject
Hi All,
The idea of using NTRIP to make a Windows Mobile GPS device sub-meter accurate crossed my mind. After some research I found this thread.
Unfortunately, I haven't been able to find any software capable of doing this. My idea is that it should be possible to accomplish this goal, using a combination of existing tools (which would be really cool!).
As wg5566 notes, there is a (WM) tool called GNSS Internet Radio, which is capable of downloading NTRIP corrections. It turns out this software works, but does have some flaws. Someone wrote another open source tool which is better (?), but unfortunately it isn't built for Windows Mobile (see: http://lefebure.com/software/).
More searching revealed a (dead?) project on codeplex: SharpGPS. It's an unfinished demo. It does however seem to be designed to do exactly what we're suggesting in this thread.
My idea: Completing the WM version of SharpGPS with parts of GNSS Internet radio / lefebure NTRIP client should result in a tool that's capable of upgrading a WM devices' gps signal to sub-meter accuracy through RTK/DGPS corrections over NTRIP.
Any ideas / suggestions about this?

It's already been done for the commercial market
Land surveyors, construction companies, and farmers use RTK GPS and RTK GNSS correction services on a regular basis. Some are free and some are paid subscription. They can be either NTRIP protocol with casters or individual TCP or UDP connections. Examples of software available are Carlson SurvCE and MicroSurvey. Read Carlson's support site for how they deal with the data flow using such networks on SurvCE (Windows Mobile and CE).
I have worked in land surveying using such equipment, and it generally requires dual frequency receivers, RTK corrections, and high quality antennas to achieve 1-2cm 95% CI horizontal precision. The current GPS chips in cell phones are only single frequency and so the best you could expect under ideal conditions is 2'-3' precision using some form of differential correction like WAAS or beacon or DGPS via NTRIP. Under average conditions, the precision will likely be in the 10-20' range. The dual frequency receivers take care of the large errors caused by radio waves traveling through the ionosphere.
Due to the limitations of batteries, antennas, and space for more chips in cellphones, the future of location accuracy will likely include some combination of GPS/GLONASS and cellular radio signal frequency timing calculations from cell towers. True Position, with its U-TDOA technology, is one example of measuring the time differences of cell phone radio waves using cell towers with known coordinates. Rumors (from surveying journals) have it that there are current patents in place that can allow for sub foot precision using such methods when sufficient cell towers are present for multilateration.

Has anyone found success on this topic? WM or Android...

Would be very interested, since there is a free NTRIP feed available in Switzerland... anyone?

*bump* it up

Been there still trying. Problem is no carrier phase off internal gps.

Lance lefebure is a really cool guy I'm sure he wouldn't have any problem building a wm version but it is going to takea lot more than that to get rtk to a cell phone.

Very good ,thanks.

If you are confused just ask questions and I will do my best to answer them. I am in the ag industry and deal with RTK networks and different ways of connecting them and tons of different gps units on a daily basis.

Nope PDA with support for external GPS with a builtin reciever that even sees glonass satellites (russian constelation). That was made specifically to do RTK mapping. It does have a GSM radio for data to connect to the cors.

Phone positioning using CORS
To perform a CORS (Network Reference correction we need a GGA stream from the GPS in your device. This allows us to remove the anomalies and provde the correction stream. As phones use a sirf II chip or similar they do not have input capability to output the NMEA stream to achieve this.

This one works great! it will connect to an Rtk receiver and get the nmea string from it or will use the internal GPS to be able to register on the CORS network. It will then stream the corrections over Bluetooth to a receiver or even a repeater radio. It won't however correct the internal GPS. http://antrip.dyndns.biz/Home/DownloadTrial

Use HTC Touch Diamond 2 as a remote for a rc car

Hi everyone,
Okay, here is the idea. I have a HTC Touch Diamond 2 and I was thinking that it could be interesting to try to use it as a remote control to pilot a small car or plane (using the Bluetooth frequency).
I found several receivers in the 2.4 GHz frequency band, but I'm not sure whether it could work or not. Here are a few: link 1, link 2, link 3.
So the main questions are:
- Is it possible to program my HTC so that it sends information the receiver will 'understand'?
- Is there by any chance already an app that allows me to do just that (or something close to it that would need minor modifications)?
On top of this, I was also thinking of adding a camera on the car that would send back to my phone what it records. But this more than optional since it probably will make things much more complex... (I found transceivers such as this one and this one, but it looks like a lot of work to install and configure them).
Thank you for your answers and your help in advance!

Anyone to help me?

It won't work, sorry. Not with any store bought RC car. Your only chance is if you engineer the receiver yourself, including the circuitry that translates the radio signals into motor signals.

Thank you for your reply!
Ah, that's quite disappointing
But just to make sure, can you tell me exactly where the problem is? I mean is it a true hardware problem, in relation with the kind of signal that I can transmit with my phone (like a frequency incompatibility or something else)?
I was hoping it was possible to program my HTC to send the appropriate signal corresponding to what the receiver is expecting to get. Why couldn't it work?

Am I at least asking my question on the appropriate section of the forum, or is there another one that I should use rather than this one? Thx again.

Can Android device transmit radio frequency?

I have gone through many articles in the internet but couldn't find anything related to this. I wanted to know if android has the capabilities to transmit radio frequency so that it can be used for playing the songs in the smartphone directly to the nearby radio by making the smartphone as a radio station.

Yes, but you need some external RF hardware - check out GNU radio and the general subject area of Software Defined Radio.

Hmm I know some Android Phones may have it build in a Hardware for.
My "old" Nokia Phone have that native feature.

Question Alternative FM radio app for FYT-based Android head unit

Hello all,
I have an Atoto S8 which is a FYT based Android head unit.
MCU Version:
2021.04.26 13:48:17 YUF_53_L6315_G32P64F64_Ver: 1.0
CPU: UIS7862 Octa-core
I was wondering if anyone knows of or has an .apk of an FM radio app compatible with the FYT head units? I tried every app around and none of them work. The Navradio developer is still porting his app to this platform, so I was wondering if there's something else I might try meanwhile.

There are re-skins, but AFAIK the radio bits are part of the proprietary MCU

But if I got an .apk from a Joying head unit, it might work no?

I'm not so sure about that.
I think you would have to do some hand editing of some files at the very least. (To put in your fyt build number)
There is more info on it at the other forum.
I looked into it for a second weeks ago, but then I bought Poweramp and haven't really used anything else.
I agree that the fm radio all looks like crap though on my Mekede

Poweramp works with online radio?

Apparently it does. That's not what I meant, though.
I procured some 15-30 gigabytes of songs from different playlists from another source.
(I have to be vague because of forum rules)
Anything else I want, such as podcasts, I just stream via Bluetooth.

If your Atoto S8 is indeed a FYT unit, it might work.
What you carefully need to look at is the name of the apk. It has to be exactly the same as the one on your Atoto unit including installed libraries.
And then you need to write the corresponding lsecupdate.sh file and use the corresponding lsec6316update binary
and off course: make a backup of your current one.

I'm working on porting NavRadio+ to FYT units.
This last weekend, after 2 months of tries, i was finally able to get sound out of my app.
I already have control of the radio commands and infos so it's just a matter of put things together in the right way and iron out all bugs. Then i could release a first FYT version probably in the first days/weeks of the new year

I did not know you were working on this.
Please take a look at this github from lbdroid. It contains a lot of useful "reverse engineerng" information for the MCUradio for the FYT. It is still from the Sofia3GR but as far as I know hardly anything changed.

The original fyt radio app now contain code for all the platforms and each platform use different approaches. The hard part was to understand which part of code is used by each platform and how.
Sofia units control radio and audio through MCU.
UIS7862 use the native jni libs to control the radio and audio is started by MCU.
Right now I'm working only on more recent UIS7862 units, i don't think I'll adapt it to Sofia or other older units.
I know that units with canbus use another APK too (com.syu.carradio) but it's not totally clear to me what it does exactly. Can somebody explain me it?
To make my app to work, because of the native libs, is mandatory to install in OEM folder a copy of NavRadio apk (not necessarily the full apk, even a fake app with same package name is enough to set NavRadio as system app).
To do this i have 2 ways:
- directly from NavRadio for rooted units with some root commands
- downloading a zip update package to flash manually the APK in OEM folder
If you guys have other/better ways to do this, please tell me, I'm new to these kind of units..

I did "some" checking on this app a couple of years ago as I had a Skoda with Canbus. The standard radio in the Skodas (and I assume in all VAG concern cars) are partly controlled by the CANbus. The Skodas use an extension on the standard CANbus commands to switch on/off the radio in the cars when ACC is switched on/off. This is NOT a direct wired coupling of power, but really a digital on/off signal from the CANbus.
My Skoda had a simple Swing radio (hence another Android unit), but other Skodas had the MIB1 Amundsen/Columbus unit (navi/media/phone/radio/tmc and car menu). The car menu inside the radio is also controlled by the CANbus. My guess at that time (not having a MIB1 amundsen/columbus unit) was that that was also "streamed" through the carradio app.
Note: I am only sure for the on/off, the rest is an educated guess. And I assume other cars with CANbus displaying/changing "stuff" via the radio, instead of dedicated hardware buttons, do the same.
Maybe other users having a VAG (Audi/VW/Skoda/Seat) car with previously an MIB1 (or MIB2, but why replace that one?) unit and now an Android unit might have more info.
Please share.

And another question: RDS-AF on all FYT units is incorrectly implemented and already since early 2016.
Does your app has a properly working RDS-AF?
If I drive in the Netherlands from North to South (or the other way round ), I sometimes go through 7 (!) frequency regions depending on the station, but at least through 4.
Working RDS-AF functionality would really be THE reason to switch to it.
Edit: I know it works for Topway and the like, but I want to know whether it also works for FYT.

Normally AF is handled directly by radio chip. I still haven't investigated how it work on fyts.
My app can only enable/disable AF and on some units you can set the sensitivity of reception.
On MTC units that also receive the radio station ID (PI code) i added a function to merge the alternative frequencies in the same station preset in an array so that you can easily switch between them sliding up/down on the screen.
I can see in the logs that also fyt units receive the pi code but only at native libraries level (c++), i cannot handle it in java.
I know that we can change sensitivity and read the signal strength so probably something is possible to improve AF.
We'll see...

A lot of Philips TEF6686 radio chips are used and RDS is part of the chip. Some of the cheaper units use a TEF6851 which does not have RDS. Or the budget STMicroelectronics TDA7786x which does not have RDS either.
But it is still the software that "should know" how to retrieve and use the RDS info and in this case specifically the RDS-AF. The FYT software is not doing that correct.
That's why I switched in my other "deceased" car to a DAB+ module using @realzoulou's DAB-Z which uses proper "service following" (as RDS-AF is called in the DAB+ world).
That was a great solution, but I still prefer not to have extra hardware connected when it is not necessary.

I looked a bit at the logs during RDS-AF and it definitely is working wrong:
AF should search for an alternative frequency of the same station (identified by the pi-code), but somehow,after a while, if the signal strength is ok it switch to a station with a different pi-code.
All this seem to be controlled by the native library fmjni.so but i have no idea how to modify a c++ lib (maybe a revers engineering?)
Maybe I'll find some other way to handle AF using the logs but i can't promise anything right now.

I now think it even works differently for the standard FYT radio. My experience so far is only on Sofia 3GR (2 models), a PX5 and a sc9853i, no experience with the uis7862. Hopefully the uis7862 will arrive this week.
The RDS-AF only works for memorized stations. If I want to follow one station, for example NPO 2 FM, through the Netherlands, I need to add 4 frequencies (or more) and memorize these as presets.
It seems the radio app/mcu does not interpret the RDS-AF signal itself, but it seems to check (part of) the RDS data it has for a certain station, with RDS-data from other memorized stations. If part of it is equal (which part? only the station name itself?) with that other station (which you have to have memorized, otherwise it can't compare) and that station is stronger, it will switch to that station. If it can't find a stations from its memorized stations it seems to just select the strongest "whatever" station. This means that I have to blindly save 4 "NPO 2 FM" stations in the presets. And this for some other preferred stations as well. And of course: 1 frequency is what you can easily hear and set, but the other frequencies you have to google or so, because at the moment of adding it to a preset, you don't not have (sufficient) reception for that station.
"Real" RDS-AF should check the alternate frequencies inside the signal. Not do a "does some of the data look like a station I already have in memory".
I am a "restless" listener and listen to multiple stations. I switch when there is talking I don't like, a song I don't like, etcetera. I can't even memorize my five preferred stations in 18 presets.
In the Netherlands we have another deal breaker: FM frequencies are sold every five years and anyone can pay to it. It really means multiple different frequencies, whereas in some countries you only have one frequency for a station through the entire country, like in some countries in Azia.

I believe that standard radio receivers have a double tuner to handle the AF: one that keep the station tuned and one that scan all the frequencies to find the better one with same pi-code.
On MTC devices even if it's not perfect, it work correctly, the station is kept while the second tuner scan silently all frequencies until a new one is found.
On the FYT device i can hear changing frequency continuously until a stronger one is set.
I don't know yet if it try to tune the preset ones or try to find some other but anyway it's definitively not working correctly.
I'll dedicate more time to it after the first release of NavRadio app.
Right now on my app work like original app (so it doesn't work).
