AT*PSNTRG? equivalent for HL7* HL8*

IoT Modules Legacy HL Series
1

Hello,
HL series is theoretically interesting in term of hardware upgrade from GPRS up to 4G.
Problem is that some AT commands of HL6528 are not available for HL7 and HL8 namely AT*PSNTRG

At+CREG is giving part of the info from PSNTRG but not “Current PLMN Name in long alphanumeric format” for instance. Do you know how to get this info?

Best regards,
Thomas

Hi hestia,

For ”Current PLMN Name in long alphanumeric format”, you can check AT+COPS=?.

The syntax is:
AT+COPS=?
+COPS: , long alphanumeric , short alphanumeric , numeric ,< AcT>

0 unknown networks
1 network available
2 current (registered)
3 forbidden network

E.g.
AT+COPS=?
+COPS: (2,“CHN-UNICOM”,“UNICOM”,“46001”,2),(3,“CHINA MOBILE”,“CMCC”,“46000”,0)
OK

Hi sierra_klin1,
For me equivalent to PSNTRG most valuable infos are:

  • +CREG # *PSNTRG (value 6: egsm missing)
  • +COPS # *PSNTRG
  • +KBND # *PSNTRG
    I’m not sure regarding *PSNTRG state whether it is equivalent to +CGREG because *PSNTRG also indicate if GPRS is available or not on a cell. CREG will just tell us that we are registered or not but not why…

Best regards,
Thomas

Hi Thomas,

To know the registeration failure reason, I suggest you check with AT+CEER. e…g
ATI
HL7539
OK
AT+CEER
+CEER: “No report available”
OK
+CGREG: 3
+CEREG: 3
AT+CEER
+CEER: “EMM reject”,15,“No suitable cells in tracking area”
OK
