Ah, so good. Especially with the module and tablet. This build still needs external Battery or just the save()?
Nice link at the end. Lots of tinkering options :)
As a backchannel, eg for a software on the host, reporting certain state values, can one grab and use the console's serial port on the Espruino side for that so that data sent to the USB modem dev on the host would end up in some serial buffer on the Pico? I remember switching console from back then, but I don't know if that's still possible. I could of course set vars via the console via JS, but it would nice to define limited protocol on the board side.
