Can't replicate this I'm sorry... using the current nightly and TX16S, ELRS3 Lua is working for me at 400k (which is good as I almost always use 400k) for HM24TX @ v3.0.0, HM915TX @ v3.3.0-RC1, BetaFPV 2.4 Nano @ v3.1.2 What firmware version is your module running? |

It would be interesting to know if flashing that module back to 3.2 fixes it... as 3.3 includes a change to the autobaud calculation used in the ELRS firmware to connect with the handset... maybe you have a edge case where it doesn't work/makes it worse? It would at least rule that out as a possibility. |

additionally on TX12MK2 the ELRSv3 lua script does load forever with 3.75Mbaud but it works with higher 5.25Mbaud and lower 1.87Mbaud and also 400kbaud. |

It might be related to some timing that are now slightly different either on our or on ELRS side, thus making it a bit wonky. Most of the time, achievable speed on half-duplex external link is .... well.... based on a combination of available hardware options (rx/tx DMA), interrupt load on that particular radio, etc. Not something we can change that easily. |

Just quickly checked this on my Zorro as well. 3.75Mbaud does not load there either now but hardware is likely very similar to TX12 in this regard. As @raphaelcoeffic already said, I also believe this is strongly related to the hardware/software combination with timing/oszillators/interrupts etc. Maybe it is a good idea to just give somewhere a prominent hint that ELRS lua loading issues can be related to module baud rates and close the issue with this? |

Yeah, because my RM nano module works on Zorro at all speed above 921k (didn't bother testing bellow), so it is really a combination issue sometimes |

Maybe I can add to the confusion. Setup: I was wondering about spurious telemetry lost messages for no apparent reasons while bench testing with moderate distance (not too close) between radio and receiver. Made a debug build (remove Trying to narrow down the problem I found 400k to be stable with no logged errors. Anything above 400k will show the occasional Crossfire errors in the logs. Of course I tried to exclude faulty hw on my side. Same behavior on NV14, BetaFPV nano RX, BetaFPV micro module. The obvious question: ELRS or EdgeTX? Given the changes in the serial API I'd try to start searching in our own house. Sending bat signal to @raphaelcoeffic Log 1, 921k: Log 2 921k: |

We might be dealing with different types of errors here. CRC errors can be caused by basically 2 thing:
