CME ERROR: 529


#1

Hi ALL,

Im trying to conenct to my local network with AT+COPS commands and getting the error message “CME ERROR: 529”.

Background:
These are the commands with the status I have at the moment:

  1. I have no signal:
    AT+CSQ?
    +CSQ: 99,99

  2. Status of the network registration
    AT+CREG?
    +CREG: 1,2

  3. I have it in automatic mode
    AT+COPS?
    +COPS:0

  4. Error of only Emergency calls
    AT+COPS=1,2,334020
    CME ERROR: 529

  5. Using the list of networks
    AT+COPS=0
    CME ERROR: 529

Having this information, do you know if there is some step that is missing? And what other thing should I investigate to register correctly to the network?
Hope you can help me. Thanks a lot in advance! :smiley:

Hi jdelrio,
Which Wireless CPU you use? You can check the Band wave of wireless CPU with AT + WFM =2, and the strengh of signal AT+CSQ. You can check which band wave your operator use?
