  @MaBe: No, the default sensitivity was too high with the way I originally had my wires. So I had to shorten some wires and bend others to have them apart as much as the limited space allows.

  @Robin: oh, nice! might try this one day. Would be curious if I could get that to work more reliable than the ESP32 touch pins I tried initially.
  For now I'm pleased with the setup I have :)

  According to the datasheet of the CAP1188 chip: "50uA quiescent current in Standby (1 sensor input monitored)". I will investigate more, if i find that the battery drains too fast.
  But at least the cap1188 can send an interrupt, so that Espruino don't have to check the touch values continuously.
  I definitely can recommend the cap1188! At first I implemented the remote with the touch pins of an ESP32, and that did not work very reliably

  Sure,
  it's a BLE remote:
  Previous, Play/Pause, Next, Volume Up and Volume Down

  Hi Robin,

  thanks for your reply :)
  I managed to get away with the default sensitivity, by rearranging the wiring even though it's all in a very tight space.

  Hi there! :)
  I recently bought some MDBT42 breakout boards and love them :)

  Now I hooked up a Adafruit CAP1188 touch board to one of them and it works (with the https://www.espruino.com/CAP1188 module), but I would need to change the sensitivity of the board and I have no clue how to do that.

  In Arduino this would work:
  uint8_t reg = cap.readRegister( 0x1f ) & 0x0f;
  cap.writeRegister( 0x1f, reg | 0x6F );

  Can anyone point me to the right direction?
  Thanks,
  SiFu
