#Win PC and Airport mode and other misc questions.

Hi All,
I have a Win10/11 PC with "Mission Planner" (MP) running. I want to control my plane using MAVLink and upload flight plans etc. Basically do some grid mapping etc.
Toward this end, on the test bench I have configured a RadioMaster Tx and Rx module with ExpressLRS installed and enabled Airport mode.
I have performed Loop back comms tests at 9600 baud, verified the link works, then tested MP to plane link using MAVLink and this also worked, albeit extremely slowly, however I do not require high performance flight control.

Note: I wish to replace the Tx and Rx modules with my own developed boards.

Now to the questions:

  1. Using a PC and a purpose built app (I'll write), how do I set various parameters that are typical configured in the Lua file, example being Transmit Power e.g. 250mW, 500mW, 1W etc?

  2. How do I adjust the power of the Rx module? Hopefully from the PC and via the ExpressLRS link.

  3. Do ELRS commands still get conveyed between the Tx and Rx radios when in the Airport mode? Could this be a way of updating the Rx RF power.

  4. When Airport is enabled on the Rx module, is there a way to get it back into normal pairing mode with AP functionality, without reprogramming the firmware?

  5. I note the Tx module can have an OLED display and navigation joystick for toggling menu options including changing back to AP mode Airport mode.
    Does the Rx module have any support for OLED display and navigation joystick and PB's?

  6. Where can I find documentation regarding the Lua script and it's parameters?

  7. Where can I find documentation regarding the comms between the Handset and the Tx module? This gives the handset information like Packet counter, connection indicator, Packet rate, Telem Ratio, RF Power etc.

Thanks,
Neil.

Hi All, No respnses to my questions. Should I be asking these questions in another part of discord?

  1. As far as I understand, the lua isn't structured in a way where each parameter is changed by a command sent to the module, but rather all is sent is menu inputs and the tx responds with the menu entries. Maybe you can look at the work done here https://youtu.be/Ubkx9XPAR6A for web based LUA interaction through usb.
  2. You might want to consider using #mavlink-rc instead if you want normal rc operation too. (check pins)
  3. I do not believe there is any support for rx joystick and oled.
  4. There is no code documentation that I am aware of.
  5. Part of this is just CRSF telem otherwise, for how the lua menu is handled probably here https://github.com/ExpressLRS/ExpressLRS/tree/master/src/lib/LUA .
