• Ah that's super interesting - all my modules were purchased in the past month, from a mix of Adafruit and Amazon (I needed next day, so I bought the kit).

    • The official Espruino boards were just flashed up to 2.08_189 with NRF Connect
    • The bare modules were SWD/J-Flashed with espruino_2v00_mdbt42q.hex, then NRF Connect flashed up to 2.08_189

    But interestingly, I also got it running on an MDBT42V (the super tiny new one from Raytac) using the same method, and on that board I do manage to get ~20uA sleep!
