AT (ATtention) commands can be used to test a UE (User Equipment) in a telecommunication network.
Here are some commonly used AT commands for testing UE:
-
AT: This command is used to check if the UE is responding.
-
AT+CGSN: This command is used to get the serial number of the UE.
-
AT+CGMI: This command is used to get the manufacturer name of the UE.
-
AT+CGMM: This command is used to get the model name of the UE.
-
AT+CPIN: This command is used to enter the SIM card PIN code.
-
AT+CSQ: This command is used to check the signal strength of the network.
-
AT+CREG?: This command is used to check the network registration status of the UE.
-
AT+CGACT?: This command is used to check the PDP (Packet Data Protocol) activation status of the UE.
-
AT+CGATT?: This command is used to check the attachment status of the UE to the GPRS (General Packet Radio Service) network.
-
AT+COPS?: This command is used to get the network operator’s name and information.
-
ATD: This command is used to dial a phone number.
-
ATA: This command is used to answer an incoming call.
-
ATH: This command is used to hang up a call.
Here are some useful links to AT command references and resources:
