Sporadic Sleep

Hi there,

one of our customers noted, that their sensors are sometimes not discoverable the next morning after they lock them away at night.

They can get them to advertise again by powering them via USB, but they immediately have an almost full battery, so we do not think that they ran out of battery over night. Instead we assume that they somehow entered sleep mode.

We do neither reset the boards, nor do we request sleepModeOnReset / powerSavingMode at any point.

Could it be possible the boards enter sleep mode on their own? Can we somehow prevent that?

Thank you and best regards,
Marcus Georgi


  • Plugging in the USB cable will show the board at full charge. Given that, this behavior sounds like the board is out of battery, not entering sleep mode on its own.
