Hitec protocol using the CC2500 RF component
Protocol number: 39
Sub protocols:
- Optima (0): the TX must be really close to the RX for the bind negociation to complete.
- Minima (1): untested
Optima supports basic telemetry using the FrSky Hub format: RX volt, TX RSSI,&LQI
Implemented debug output on uart1 for stm32
Replaced hardcoded eeprom offsets with documented constats
Fixed a bug affecting telemetry on Atmega328p using the invert_telemetry flag.
This feature will not activate the selected protocol unless a bind is
requested using bind from channel or the GUI "Bind" button. It is only
enabled if bind from channel and autobind are set since I think they are
working well together.
The goal is to prevent binding other people's model when powering up the
TX, changing model or scanning through protocols.
There is a new blinking pattern associated to it as well as a new status
"Waiting for bind".
This feature is enabled by default in _config.h .
- rewritten the handling of the incoming over the air telemetry packet
- rewritten the TX_RSSI calculation (link frame[4])
- added RX LQI and TX_LQI information in the link frame (frame[5] and
frame[6])
This allows the multi module to tell the TX software (e.g. OpenTX) which telemetry protocol is in use. Also Status of the module and signaling binding/invalid protocol
Changed telemetry configuration and validation for AFHDS2A and HUBSAN
Added default Bayang telemetry from Silverxxx:
- Option=1 to activate telemetry (option=0 -> standard Bayang protocol)
- Value returned to the TX: RX RSSI, TX RSSI, A1=uncompensated battery
voltage, A2=compensated battery voltage
