Hi
I want to receive a radio signal on my smartphone. I am using a DVB-T stick with a RTL2832U chip. In Google Play store I found a RTL2832U driver. What do I need to do in B4A to connect to the USB port and read in the data? And how can I store these data in order to process it?
A little bit of background: I am a gider pilot and instructor. Most of the gliders today are equipped with an anticollision system called Flarm. Flarms sents on 868.3 MHzand it transmits a certain set of information. My idea is to use the SDR approach (e.g. SDR Touch) and try to receive the Flarm signal. The signal contains the glider ID and also the GPS data. If that works, then I could use a little map in order to visulize the glider position in the vicinity of the airfield.
My main problems are now:
Thanks a lot for any help, hints and comments.
Kind regards
René

My main problems are now:
- connect to usb
- read in and store the data
- understand the signal
- find out which "sentence" Flarm uses in his transmission
- decode the signal
- visualize on a Googlemap
Thanks a lot for any help, hints and comments.
