Multiprotocol v1.3.2.61

Change Log since v1.3.2.58

• Multi core
  • Fixed a bug preventing the module to boot when there was an existing signal on the telemetry pin (ie the internal module sending telemetry on the shared telemetry pin on FrSky radios).
• HoTT
  • Fixed the Text menu when using Sync mode.

Multiprotocol v1.3.2.58

Change Log since v1.3.2.30

• Multi core
  • Loads of code optimization with a total of 5KB saved!
  • All protocols have been touched in a way or another. Lot of tests have been done but if something is broken please report.
  • Protocols using the XN297 emulation @250Kbps use the CC2500 if the RF component is installed (no more switch from NRF to CC2500 based on the RF frequency tune value), if no CC2500 is installed then the NRF24L01 will be used.
  • More protocols are available on the CC2500 only modules: GD00X, KF606, OMP (no telemetry), Q90C, SLT, V911S...
  • MULTI_STATUS is gone: erskyTX and er9x must be upgraded to the latest test versions.
• Trainer through RX protocols
  • By default Multi uses the telemetry line to send the received channels using a RX protocol (FrSky, DSM, AFHDS2A, Bayang) to the radio. But this does not work on FrSky radios since the telemetry lines of the internal and external modules are shared (hardware limitation). On a STM32 module and with a simple hardware modification, you can go around this limitation using CPPM to send the trainer information to the radio.
  • 2 different hardware mods available:
    • CPPM to module bay pin 2 (heart beat): supported by erskyTX, not yet by OpenTX
    • CPPM to trainer jack which is supported by all radios
  • FrSky RX, DSM RX, AFHDS2A RX, BayangRX now have the CCPM sub protocol.
• M-Link
  • Telemetry is now forwarded by default to OpenTX to be decoded by the radio. Need the latest OpenTX nightly. By changing the config file the telemetry can be sent using FrSky Hub telemetry format and be decoded by other radios.
  • Previously excluded from the T18 5in1 build but now it fits and included.
• Devo
  • Full telemetry is available if the RX supports it: TX_RSSI, A1 (set the ratio to 12.7) and A2 (set the ratio to 12.7), VFAS, RPM, temperature 1&2, GPS position/speed/altitude/time.
• MT99xx
  • Added the sub protocol Dragon for the Eachine Mini Wing Dragon plane: the protocol timing might not be correct and telemetry is not supported, I need access to a TX and RX to finish this protocol...
• JOYSWAY
  • New 4 channels protocol.
• WFLY
  • Failsafe added.
• FlySky AFHDS2A
  • FS-X6B telemetry issue fixed.
• SX1276 based protocols
  • Added the option to change the RF power settings (not on the T18 due to hardware limitations). Need OpenTX latest nightly. The power displayed is the output power of the SX1276 itself and does not take into account an external power amplifier.
