Bought a pair of these on Amazon (Store page) with the intention to install Meshtastic on them. One of the reviews suggested that the correct firmware to install was the Lilygo T-Lora V2.1_1.6, so I used the web flasher to install it.

I’ve gotten as far as the screen above, but there’s no select button. There are two controls, a momentary switch labelled RST on the store page, and an on/off switch. The on/off switch doesn’t seem to do anything at the moment, and the RST switch just reboots the device.

Is it looking for something connected to a particular GPIO pin?
