Still can't get control over the USB serial interface to work. This is the full output I get in minicom after resetting the Heltec V3, after which the port is no longer responsive. #Meshcore #LoRa

Having trouble figuring out how to #Meshcore on the Heltec V3 I got. Everyone is all "web installer" this and "web installer" that, but I'm not using Chrome. >:(

#lora #MeshCore

#meshcore reshared this.

Can't use the web flasher. I refuse to use Chrome.

The MeshCore UI comes up just fine on the device's display, by the way. I don't think it's a problem with the flashing process here.

@enot
if using any companion, serial on a minicom can only be used to get some logs, if enabled (and you shouldn't get logs if using usb_companion) ...

To interact with the node you'll have to use a client that talks companion radio protocol (android client, web client or meshcore-cli) over usb or ble depending on the firmware you installed

Thanks! That took care of it for me. :D
