I have NM setup with ModemManager and GSM modem, and can bring up the

I can see that the modem is being unlocked ok, and is indeed
registered afterwards. And a retry of the 'conn up' also works.
I wonder if there's some sequence/timing issue on the first time,
when the modem has to be brought out of locked state. (I leave the
enabling to NM/MM; with the PIN in the NM connection settings).

NM log is below. I *think* the point at which it goes awry is
indicated by the
 'enabling' --> 'disabled' (reason: unknown) @ 12:51:37
Unable to spot at the MM end of things [these logs omitted here]
what's triggering this change. Could it just be a timeout? (circa

Can you grab MM debug logs for this sequence too? I can't see what it
would be from the NM side, maybe having both together would help.



I also notice that at 12:51:36, "enabling_started(): Flashing primary AT port before enabling..." is 
occurring *twice*..?
