FrySky Smart Port (Telemetry) - Object Available?

Thanks in advance for any help provided!

Attempting to send global variable data from a P1 FLiP 32123 to a FrySky X20R using SmartPort.

Once received on the FrySky I'll use Lua and Ethos to create a custom telemetry display screen.

I'm pretty close ... I can provide Saleae Logic Analyzer screenshots and my current code if needed. But ... maybe someone has already done this? Can't find an Object on OBEX.

Relevant info provided...
-TD SR12 is actively polling

  • FLiP is receiving SPort traffic
  • Inversion, Baud Rate, Parity, Stop Bit are correct (or at least seem correct).
  • 4.7K Ohm pull-up on the in/out Pin. Pin shifts from input to output during half duplex comms.
  • Code is trying to respond...
  • Keep getting a 0x00 framing error after the initial poll of 0x7E 0x1B. Perhaps a stop bit error or timing isn't correct...?
  • Transmit byte routine is not producing a clean UART frame on the S.Port line ... not the receive side.

Thank you!
