Hello,

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:

Syntax:
^SMONI:
ACT,ARFCN,BCCH,MCC,MNC,LAC,cell,C1,C2,NCC,BCC,GPRS,PWR,RXLev,ARFCN,TS,timAdv,dBm,Q,ChMod
Example:
^SMONI: 2G,673,-89,262,07,4EED,A500,16,16,7,4,G,5,-107,LIMSRV

BCCH:

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?

Best regards,
Sebastian
