Silvano Seva 24c4a25b2d Made "static" all the variables local to each translation unit 2024-02-01 11:07:20 +01:00
Silvano Seva 91c0965007 Module17: made M17 baseband output have correct DC bias and amplitude 
Removed an old workaround for an hardware bug of Module17 rev 0.1b limiting
the output swing of baseband signal in newer hardware revisions.

Niccolò Izzo 4697be5ea6 Fix squelch behaviour on T-TWR Plus 
On LILYGO T-TWR Plus the squelch was being controlled by AT1846s,
resulting in the squelch bar setting being completely ignored. Now we
are introducing the support for a new command of sa8x8-fw called
AT+AUDIO that controls the muting or unmuting of the speaker power
amplifier, enabling us to:
1. Disable AT1846s embedded squelch
2. Enable OpeRTX squelch
Also fixed a bug where the sa8x8-fw version was incorrectly checked.
AT+AUDIO requires sa8x8-fw version v1.3.0.r1, bumped version check in
OpenRTX.
