I am using Telit HE910 modem,
After sending AT+CMER=3,0,0,2 I always got "sim card is busy".
The followoing is the part of log:
ofonod: Aux: > AT+CMER=3,0,0,2\r
ofonod: Aux: < \r\n+CME ERROR: 14\r\n
ofonod: +CMER not supported by this modem. If this is an error
please submit patches to support this hardware
My question is :
How important is this command.?
I mean what the worst consequence will be if I just ignore this error
CMER is used to set the appropriate CIND mode. For Telit this is mainly
used for signal strength reporting, so if this is not set correctly
there might be some side-effects in that area.
