Android app reading data from rs232 - canbus - Android Software/Hacking General [Developers Only]

Hi!
We're going to start the development of an exciting project, and I've got some doubts which I want to ask them out here.
We've got a canbus info grabber hardware (intendia ureader) which monitors buses. That device has a rs232 port to connect other stuff.

The intention is to have an android application "listening" to that rs232 port for information provided by the canbus. To accomplish that, we'd connect the phone using an USB OTG cable + usb 2 rs232 converter to the ureader. Would this arch work? There's a github project which provides mechanism to make use of rs232 ports.
That'd be the production environment. To make tests and further development, we modify a little bit that architecture that way. As we won't have a bus in our offices (it'd be funny :laugh, we need to simulate with a computer the transmission of data from intendia ureader. So we would connect the rs232 port (intended for connection to the ureader) to another rs232 to usb converter connected to the computer. Within the computer, we'd send data using hyperterminal or similar software.

Would this architecture work?
Thanks for your help!!

should this thread me moved to another subforum?

TV Output

I was wondering if someone had a .cab for the TV Output. the ROMs i tried don't have TV Output included. Nothing happens when I plug in my Topaz to the TV even after I edit the registry
The topaz doesn't have TV out(nothing you can do will make it work). What are you using to connect?
oh damn alrite. It use to work on HTC Fuze i thought it would of worked on the Topaz.
thanks
depends on how you have connected the phone to the tv...
you need a orginal cable
or
cable adaptor from usbmini to mini-jack + mini-jack to phono + changing the reg key
cant remember if its left or right sound cable that the tv-signal sends out
depends on the need for showing the mobile on the tv.
many flatscreens have usb and you can mount the mobile as a drive for viewing pictures and recorded videos
There was a very long thread on this way back - nothing will make it work. If the TD2 doesn't have the hardware inside, which it doesn't seem to, no amount of registry editing or cab instals will make it work

[App] Rendezvous Reminder- Seeking your feedback

Hello Everyone,
I am Omkar Bapat and want to present my idea for your feedback.
Rendezvous is an Android app concept that grew out of a personal need. As I go about spending my day at work I often recollect different tasks that I would like to do when I connect my Android phone to my PC via USB cable. However I often forget these tasks when I connect to the PC.
These tasks are things like backing up the data files of different Android apps that I use, the songs and videos I want to download on my phone, cleanup of my memory card, saving the photos etc etc.
So I thought of creating a simple app that will popup everytime I am connected via USB cable and show me the pending tasks. I have created 2 prototype screens. I am seeking the feedback of the Android community before I proceed further. Looking forward for your comments!
1) The main popup screen that fires up when USB is connected

[Completed] Selfie stick compatibility with tablets

Hie all i am working on an automation project and one of the aspects of it is to take a photo of s rock samples using a hacked selfie stick controlled by a micropocessor like raspberry pi. The hacking only involves the button of the selfie stick only.
My question is, can a selfie stick/bluetooth remote work with android tablets? i would like to know before i commit funds to buying. If there is any means of controlling it via remote control (without use of cables- has to be wireless) please let me know. The tablet is a generic Industrial tablet used on microscopes but it has bluetooth it was supplied to us by the project manager so its the only one we have to work with unfortunately.

Hi there and welcome to Assist,
There's no dedicated forum for your device here and I didn't find any info related to your problem. Try searching about on Google.

Program android device to display car information?

Hi all,
I'm considering / planning an android project to upgrade my car stereo system/screen, and I need your opinion regarding an aspect.
So as for today, my car has an old school stereo and an old school screen that displays basic information, and I'm wondering if I can remove these two modules, and replace them with a single android device that will provide same functionality.
The following picture shows the desired transformation:

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
as you see in the upper picture, lower part of the dash has the stereo, and above it is the screen,
I'm sure that an android device can fully replace the original stereo and provide same functionality.
As for the car's original screen, this is the tricky part for me. This screen shows information such as the configured AC temperature, AC fan speed, fuel consumption etc. and I'm wondering if there is anyway to develop some android application to read all of this data and display them on the new android device?
anybody done something similar?
Thanks.

Question USB Network via cable

I have a question.After an upgrade of my head unit with a PX6 I have no WIFI or Bluetooth. The question is, is it possible to connect the headunit via USB-Ethernet adapter direct via UTP-cable to my router in-house. I can realize a test setup for the unit in my office, but am not sure if this will work? An experience with this setup?

If you have a PX6 you are in the wrong forum.
If you have FYT now after your PX6, then the answer is: No, this will not work. The USB stack is blocked to only allow the "FYT approved" USB devices and a USB ethernet dongle is not one of those devices.
I'm using an FYT/Atoto device with USB-to-ethernet dongle. It won't work while you're using USB debugging however.
If you're in developer options, once you select the second option, it'll disconnect your dongle.
