I’m using usb ports 2 and 3 for communicating with my EG25
Port 2 is used only for commands and reposnes (including URC)
Port 3 is only used for data connections.
I’m setting my SMS notification parameters as below and it works as expected. I get the full SMS notification with the full PDU.
Once I go into data mode on port 3 I no longer get the +CMT URC but instead get the +CNMI notification with the index (sometimes -1) that a notification is received.
After I shut down the data connection there is no change to this behavior and a query to AT+CNMI?
results in +CNMI: 2,1,0,0,0.
Is there a way that I can prevent this change in behavior?
ABORT “NO DIALTONE”
ABORT “NO CARRIER”
ABORT “NO ANSWER”
