- Maybe integrate a TNC Modem with KISS interface? (I am not sure if that is worth the effort)

## Notes on APRSdroid
|
||||
Although theoretically not an issue, currently APRSdroid is not supported due to the following two issues:
|
||||
- According to https://github.com/ge0rg/aprsdroid/issues/156 the sample-rate is fixed to 22050 Hz.
|
||||
Currently, only 48000 Hz is supported (and 24000 Hz would be possible to implement).
|
||||
However 22050 would require a different timebase and is thus not possible unfortunately
|
||||
- Currently APRSdroid does not support any PTT control via a serial interface.
|
||||
Currently, only 48000 Hz is supported by the AIOC (and 24000 Hz or 12000 Hz would be possible to implement).
|
||||
However the required hard-coded 22050 Hz would require a different timebase or resampling and is thus not possible unfortunately
|
||||
- Currently APRSdroid does not support any PTT control via a serial interface. See https://github.com/ge0rg/aprsdroid/issues/324
|
||||
However my previous experience is, that the Android kernel brings support for ttyACM devices (which is perfect) so implementing this feature should be no problem.
