ruuvi_interface_lis2dh12.c:175 FATAL: SELFTEST

[rinat-enikeev]

I've faced the problem with 2 of my RuuviTags - in connected state they were restarting with the

ruuvi_interface_lis2dh12.c:175 FATAL: SELFTEST

error. Re-programming didn't help. Next morning the issue was "fixed". Without any action from my side.

The tag advertised ok, but didn't heartbeat.

The LIS2DH12 lacks a proper soft reset, I've seen some bus related to LIS2DH12 survive reboots and reprogramming tags. I'll start by checking that a failed selftest cleans up the state of LIS2DH12.

My 06DC (B7.1) tag after reset reports:
