## Notes on APRSdroid ## Notes on APRSdroid
Although theoretically not an issue, currently APRSdroid is not supported due to the following two issues: 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. - 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). Currently, only 48000 Hz is supported by the AIOC (and 24000 Hz or 12000 Hz would be possible to implement).
However 22050 would require a different timebase and is thus not possible unfortunately 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. - 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.
