Niccolò Izzo 2dabacebd8 ttwrplus: Implement power control on SA8x8
Implemented power control in T-TWR Plus by using the embedded switch
(RADIO_PWR) that controls the H/L pin of the SA868.

Niccolò Izzo c276fc5a51 ttwrplus: moved all the SA8x8 code in a dedicated translation unit. 2023-09-20 21:08:35 +02:00
Niccolò Izzo eeb05bcc0f ttwrplus: fix unstable baseband startup
A proper baseband reset is now issued at each startup. Now OpenRTX check
for SA868 responsiveness before proceeding with radio initialization,
eliminating unstable behaviour at boot.

Niccolò Izzo dc84908fbc ttwrplus: enable TURBO mode on SA868S
Enabled AT+TURBO command on SA868 that switches the baud rate of the
serial communication from 9600 to 115200 to get a more responsive
baseband. Bumped up the required baseband firmware version to
v1.1.0.r20.

Niccolò Izzo 4c035bbf16 ttwrplus: enable Tx capability
Enabled Tx capability on T-TWR Plus.
Since Tx requires the SA8x8 to disable the Rx stage, we check that at
least firmware v.1.1.0.r14 is present on the baseband, otherwise we
don't initialize the radio.

Niccolò Izzo c60f580396 ttwrplus: add support for SA868
Add support for initializing SA868 and querying its firmware version,
created a new instance of the AT1846S class that leverages the SA8x8
serial connection as an i2c implementation.
Rx works! In the sense that the RSSI bar behaves as expected, still no
audio.
