ModalAI Forum

@Omri-Eival The Zorro Blue User Manual should answer most of your questions, with a shell script to copy all of the latest data to a handset in the provided zip file. While you are there, if your firmware is out of date it may be worth going through the update process.

The M0184 ELRS receiver is able to be flashed with the ExpressLRS Configurator; however, it requires you to use our forked firmware repository. The instructions for using ELRS Configurator with our receivers are here: https://docs.modalai.com/elrs-configurator.

@latif You should be able to disable the model match feature on the same screen which displayed the "Model Mismatch" error. By setting the model match id to 0, it will ignore the model match id set on the receiver and connect. The ExpressLRS documentation has more detail about how to set up the RC connection here.

@wifa799 @Viktor-Gal You can use any CRSF (ELRS) receiver with the VOXL 2 and it will work. While we don't support flashing upstream builds of ELRS from the VOXL, if you update it yourself it will work without requiring any additional modification or patches. The patches from ModalAI just include some extra utilities for managing the receiver with the voxl-elrs tool such as the "unbind" command and pwm configuration from the VOXL. I'll see if I can provide a build for the betafpv receiver which matches the 3.5.3 version provided for our in-house M0184 receivers, but in the meantime you can definitely use firmware from the upstream ELRS repo.

@Viktor-Gal ELRS maintains compatibility between all versions with the same major version number, so a 3.x.x receiver is compatible with any 3.x.x transmitter; however, a 3.x.x receiver is not compatible with a 2.x transmitter. Because of this, you will need to update the transmitter in your handset. You can use the upstream ELRS firmware for this since we don't make any modifications to the firmware for the iFlight Commando, instructions are here. I suggest using the latest firmware version available, you can flash older firmware later if necessary. All customization and ModalAI provided models on the handset will persist through this process.

Hi @tkddnjs825,

In addition to Alex's question above, could you also please share which version of voxl-elrs is being used on each voxl2? The voxl-version command should list the versions of each installed package.

Can you also please confirm that in the voxl-px4 configuration file on the voxl2 that is not able to communicate with the ELRS receiver that the RC type is set to CRSF_RAW, like this: RC=CRSF_RAW.

Furthermore, if you could share the output of voxl-elrs --scan from the voxl which is unsuccessful that would be helpful.

Thanks,
Max
