@FiiO: About my M11 Plus ESS reboots... I managed to find a reboot from logs... IMO it seems to be related to wakeup from sleep i.e. sometimes M11 Plus ESS loses power or crashes completely when waking up.
Seems to happen only when wakeup reason is this:
6,15009,1320293335,-;[soft_i][98989111625][08:26:25.087413] wlan: [0:F:WMA]
WLAN triggered wakeup: BPF_ALLOW (39), vdev: 0 (STA)
and never when wake-up reason is:
6,965604,39926801612,-;[soft_i][2674815812739][07:01:26.811502] wlan: [0:F:WMA]
Non-WLAN triggered wakeup: UNSPECIFIED (-1)
