First time startup of HL7648 purchased from US distributor.
LTE type.
Both antennas are connected.
CREG reports it is connected to the network.
When I try to dial ATD[number] it immediately returns “BUSY.”
The following commands result.
xxxxxxxx means edited identifying info.
+CREG: 1,“FFFF”,“52xxxxxx”,7
+CGREG: 1,“FFFF”,“52xxxxxx”,7,“00”
According to the AT manual:
“FFFF” means the is location area code is invalid.
“00” means routing area code is invalid.
More command results:
+KSUP: 0
+PBREADY
+COPS: 0,0,“xxxxxx”,7
+CPIN: READY
+KCELL: 1,5,13xxxx,52xxxxxx,167,36xxxx,36,23,0
The codes signifying invalid parameters are related to the permanent BUSY when dialing. What is causing it?
