[Q] Using CDMA like a GSM telemetry link? - General Questions and Answers

Hey guys, wasn't sure where to post this but I figured I would start here.
I want to know if I would be able to use something like a remote desktop or another way to retrieve data from a serial cable to a computer over the network.
I am on a Formula SAE team for my school and a member from last year had built a car computer for use of a telemetry link. I know he attempted to use his GSM network but T-mobile capped him so low to where it didnt really ever work right.
Right now I have a Sprint Epic 4G Touch. I was wondering if there was a way to link my phone to either the car computer or the actual CDS data acquisition system just to see live data coming from the car as opposed to logging the data and viewing it later.
I still have to boot up the car computer and see whats all on there as far as specs go but I did snap a few pictures.

Basically its just a serial port out from the data acquisition unit to the computer. Just seeing if there was a way to go from the computer to my phone for the telemetry option. Or if there was a way to fab up a serial cable or unit directly to my phone so I can see the raw data at a computer nearby.
Any information regarding telemetry would be much appreciated. Thanks!

Let the social be with you.
Launch WiFive application and immediately start chatting with whose who is using it too within your Wi-Fi network. No Internet needed. Also, there is no need to set up a server. Simple, eh?
But of cause there are some conditions.
In order to receive messages your device should not ignore broadcast UPD packets (as long as I know some devices are doing it, for example HTC)
Your Wi-Fi network should not block UPD packets (as long as I know some network managers are doing it). But it's OK if you are creating Wi-Fi Spot yourself. Google it, it's pretty straightforward.
Also, be aware of some possible message loss.
Have fun with unlimited communication!
Application is also available in Google Play.

I believe you can't make that open source..?
Hi your application is exactly what I need. I want to built a rover controlled by an arduino that is connected via usb to the first android phone. With the second one I want to send the control data (speed, direction). I've already implemented the control of the arduino and i can stream the video to my controller application. Your application would be the perfect way for exchanging the control variables between my phones.
If you could post the source code it would really help me a lot!

Some app named System tries to connect various IPs...need help in figuring it out

I got a Moto G phone running Oreo. I have a firewall installed, and its logs show an app with the name "System" trying to connect to various AWS hosted addresses. The phone is not rooted. I am trying to find out which process this System actually is, and what is its purpose. I am trying to somehow capture some traffic and find something.
If anyone knows what exactly this is and whether I should be worried or not, please let me know.
Here are some of them:

I found some more information using logcat:
[ 10-19 17:12:33.467 1229: 1309 E/LocSvc_xtra2 ]
connect:204] connect to 54.230.93.211 failed
This is one of the IPs that System process is trying to connect. Some googling tells that this is Location Service being used probably. I have GPS turned off completely when I don't need it. I have also given access to GPS only to OpenMaps application which isn't running at the moment. All google apps are in disabled state.
I also noticed that these connection attempts happen every 5-6 minutes.
I cannot use strace as don't have root. I am trying to route the traffic from the phone through my PC to be able to capture network traffic.

How to see the devices that are connected to my hotspot in Android device?

So, I've been looking all over the internet for 2 years (approx.) from time to time for this query.
My device: I have a Motorola X(4) device which came with near stock Android.
My question: how can I see who is connected to my hotspot.
What have I tried so far: I see apps in playstore for scanning Wi-Fi and not what I want (which is to see devices connected to hotspot). I've search for web with no helpful answer, everyone seems to confuse about Wi-Fi scanner. I don't want a Wi-Fi scanner
In few answers I see people showing steps to do this, but I don't see the last option 'View Who is Connected' in my device. I have attached screenshots for reference.

Hi there,
Although motorola is close to stock Android, they have the annoying manner of removing very little, yet useful features like that. You're supposed to have a menu to see what device are connected, like me (I'm using OxygenOS, and even with their "overlay" they left the feature).
Unfortunately I don't know how to help you on this one. When I had a motorola (Moto E 2015 LTE) it didn't have the "enable wireless display" option for screen casting m. I've search a long time, and finally found out about that annoying manner motorola has. The solution was to modify one or two line in the build.prop file.
Hope you'll find out one day

GT-P3113 - Data Cable - Pinout/Wiring Diagram?

I have P3113 - Tab 7.0 Wifi/IR blaster. The cable that came with it (ebay) does not seem to support USB data connections. charges just fine. I bought another wire online (this was years ago) to no avail, still no data connection.
In comparing to the image here: https://pinoutguide.com/visual/gen/samsung_galaxy_tab.jpg (with pins being numbered 1 on the right and 30 on the left, I have pins:
3USB_DP_CON I/OUSB Data +4USB_DM_CON I/OUSB Data -
7V_BUS_1 P 8V_BUS_1 P
15Gnd P 16Gnd P
30Gnd P
Which seems like it should (?) work for data transfer with a computer. (make a lot more sense than the inverse)
I've looked around and have seen a lot of pintouts to modify things to support audio or whatever else, but does anyone know if the pinout I have is valid for USB data transfer? Is there something I can do to get the data connection working? Or do need to play some roulette with cable buying? (Any recommendations?)
I've popped the casing off the plug and it seems like wiring there should be mapped correctly, though it does look like it's cheap for sure, but there's no resistors or anything, wasn't sure if there needs to be for "standard" data usage.
Any thoughts would be great. I'm not looking to do much more as to hardware hacking right now, just getting it rooted and then more or less a simple controller.

Hi guys first time posting,
So before I start I’m sure this type of topic as been asked millions of times and I’m not posting this blind, I have put in some research into it albeit with my limited knowledge. I’m 90% certain this is a lost cause but here’s to hoping this community can help.
My mother has given me my uncles old phone after he passed away with the task of retrieving old family photos. It’s PIN locked and despite trying lots of possible combinations I’ve had no luck.
There is no custom roms installed and I doubt debugging is turned on, when plugged into a laptop it’s not recognised by the system (I believe the mode needs switching, but requires PIN to access that)
The phone in question is: Motorola G9 Plus
The phone does have a SDcard slot.
Any advice/help would be greatly appreciated.
Do a Google search for "Motorola G9 Plus FRP Unlock Tool".

Does this not require factory reset? I’ve watched a couple of the videos and read a few articles, they all seem to start from a fresh install.
I’m currently locked at the PIN screen and don’t know how I would get to that stage without factory resetting
