 - 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.
