I’ll try that, but for now, I’ll just use a second arduino. Now my next problem is that I can’t correct my earlier mistake in setting the parameters for serial communication. I incorrectly configured the RX and TX pins as 9 & 8, but I believe they are 7 & 6 (if i have read the pinout diagram correctly). If I use the client.meshtastic.org interface I always receive a error message when I press save (an unhelpful ‘there was an error in the save’ message), and if i use the phone app, it does not give and error when i save, but changes nothing. Is the device just quirky, or is this user error, or do I only get one shot at doing this right and modification is just not supported?
