Description
Right now the signal meter (S-Meter or RSSI) is always displayed in the app, on both the voice and APRS chat screens. This is usually desirable. However, there's some hardware defect in the SA818S/DRA818 radio modules whereby nearby transmissions somehow overpower it and corrupt the rx audio (causing a click) whenever RSSI is sampled. This is not normally a problem out in the field, almost only in a "bench test" scenario.
However, if someone has some special use case where they DO need a kv4p HT to be near to a strong transmitter (or near another HT), this setting would let them turn it off and remove the clicking, although they also lose the S-Meter display. This would almost certainly only be for things like specialized packet radio use cases where multiple node smight be near each other.
- A new setting needs to be added to the in-app DB.
- Here's the code to show/hide the S-Meter UI and tell the microcontroller to start/stop using RSSI:
Turn it off:
radioAudioService.setRssi(false); findViewById(R.id.sMeter).setVisibility(View.GONE);
Turn it on:
radioAudioService.setRssi(true); findViewById(R.id.sMeter).setVisibility(View.VISIBLE);
