I'm not quite sure what you are asking for here. If you mean can EdgeTX make it so the builtin RF be used as ELRS, then that is well beyond the scope of the EdgeTX project. EdgeTX is not responsible for the RF link, that is the responsibility of the built in (or external) RF module. If you mean for an internal module to be able to be replaced with an ELRS module, then assuming it is wired up correctly, EdgeTX already supports this. |

Did you think it will work without any modifications? I can try it after 7.10.bcause vaccation |

The whole concept of what we are doing is a modification. I can't tell you to be honest. My last PCB revision came in a week and a half ago and I've spent most of my free time since troubleshooting and getting help from others. It was only last night that I finally got it to work. I am leery of using the 5V lines for power because I would hear weird sounds coming from the handset's speaker. Instead I ended up taking power from Vmain on the main board and using one of the 5V lines as an enable source for a 3.3V step-up step-down regulator. |

The "weird sounds" are most likely due to RF - it's normal even for recent radios to have noise, which is why they often hard-kill the speaker/amp when not actively playing sound. Simply because they didn't want to add the extra power filtering or regulator 😆 |

Is it them, or us? Cause when I used to use the OEM internal RF module, those sounds weren't a thing. |

If it didn't buzz/noisy before, probably us/the mod. ;) However, in the case of some of the radios I have, particularly as they get a bit beefier with the internal ELRS, have noticeable noise in the background while the speaker is active. So probably not enough shielding or power filtering. |

And to help out even more, maybe he just didn't find the option for it. In 2.7 the setting for internal module type was moved. Press SYS button, go to Hardware tab, scroll down to Internal RF. You can change there to internal CRSF, it will let you use Crossfire / ELRS modules internally in the radio, either via official modules (Radiomaster ELRS module for example) or hacked in (you can put a Crossfire Nano TX inside the radio and just wire it in). |

For the old FRSKY transmitter, is there any way to support built-in CRSF or multi-protocol, can we support full-duplex URAT function in the vacant IO port of MCU? |

@caixiaohai0 theoretically, this is just about defining the proper pins/UART in |

It's working as internal Module (Hardware - internal Module Crsf)

Is there an existing issue for this feature request?
Is your feature request related to a problem?
The popular use of elrs now makes the built-in RF modules of some remote controls deprecated. Most of the built-in interfaces can be DIYed into built-in elrs social-level modules. I hope EdgeTX developers can add the built-in crsf protocol, thank you.
Describe the solution you'd like
Turning on the built-in crsf protocol makes the player DIY still the built-in tuner of his own elrs
