Switched to int32_t for RSSI representation to allow running the code also
on devices with limited resources. Defined a new ad-hoc type to still keep
the possibility of using floating points on more capable devices.
General code optimization allowing to reduce the overall binary size, especially
for devices without hardware floating point support. On the MD-380 (which has the
FPU) the .text size has been reduced of 4'928 bytes.
The "revisions since last tag" version field is now accurately named and no longer checked. Extra parentheses also added to reduce compiler warnings.
Fix#217
Fixed error in compuation of values for AT1846S frequency registers
causing the output frequency to have an effective resolution of 1kHz
instead of 62.5Hz.
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.
TG-553
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.
TG-553
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.
TG-553
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.
TG-553
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.

TG-553
Given that each radio driver loads its calibration data when initializing
and that the radio driver is strongly platform-specific, there is no strong
need for an intermediate redirection layer through the platform API.
