I will try lowering the baud rate in tomorrow's run. In the meanwhile, I've been able to narrow down the exact symptoms of the problem.
Sequence: 1. AT+CMGL=4 times out because it did not receive the terminating OK 2. Subsequently, the KeepAlive or Watchdog thread gets a CMS Error 512 and marks the modem for restart Question: Is the CMS Error 512 the underlying cause of the timeout or just a symptom of timing out and aborting the AT+CMGL? --Nizam On Dec 10, 2:06 pm, "T.Delenikas" <[email protected]> wrote: > Hi, > > This Siemens MC35 issue used to come up in the forum in the past.
