If the device is blocked from getting signal, it will not acquire a signal again. CSQ is always returning 99,99 in this case and was tested for up to 5 minutes without restarting the radio. This is a showstopper for our application.
This is running FW 5.5.23
Place the device into a something that can block RF completely. We used an ESD bag [instead of an RF box which still had some signal (CSQ returned 1,99 typically in the box). In the bag, we were able to get it to 0 or 99. Taking it out after the 0 or 99, CSQ never improved even though it was in free air at that point.
What is the proper sequence after having no RF? Should we try using CGATT in hopes of getting a connection?
More details. If COPS=0 is ABORTED, it seems CSQ ALWAYS comes back as 99,99
What is this cause, is it a bug in the COPS command when the network is low? Should ABORTED be an unacceptable response putting the radio in a funky state?
