Hello Denis,

> The 5 second timing is suspicious.  oFono core does set a timer and =
will invoke a .disable() if .enable() doesn't succeed in a given time.  =
But the default timeout is 20 seconds (see src/modem.c =
DEFAULT_POWERED_TIMEOUT)

I bet these 5 seconds are just coincidence as oFono agitated the power =
button GPIO beforehand. I saw this timeout and already increased it to =
45 seconds to check if there maybe log delays in responses from the =
modem and the original timeout would mask them.


Best regards,

Christian
