several time we receive a bad value of "144" dbm in the BCCH field of the AT^SMONI AT-Command during 2G data connections:
AT TX ( 8): AT^SMONI AT TX ( 1): <cr> AT RX (11): <cr><ln>^SMONI: 2 AT RX (11): G,986,144,2 AT RX (11): 62,03,C7D7, AT RX (11): 32A1,58,58, AT RX (11): 3,1,-,LIMSR AT RX ( 3): V<cr><ln> AT RX ( 1): <cr> AT RX ( 5): <ln>OK<cr><ln>
Syntax according to the manual:

BCCH Receiving level of the BCCH carrier in dBm (level is limited from -110dBm to -47dBm)
What is the reason for this out-of-range value?
In AT^SMONI response the BCCH value of 144 can be sometimes observed in 2G, in special circumstances, e.g. when the command is called when our module performs network measurements or during cell reselection. Please ignore this value in your application and BCCH value will change back to a correct value afterwards.
thanks for the reply. We will handle the case as you proposed.
