Hooray! I found another device and it flashed fine. I guess the one I was using to start with had a flakey BT radio or something. Used nrfConnect to flash everything except the initial DaFlasher .bin file, thanks for the tip on that. Now have a watch with @jeffmer's Watch build of Espruino on it 🙌
Thanks for all your help @fanoush, and for the Magic3 build of Espruino!
