AT#CSURV without simcard

  1. Hello,

     

    I’m trying to perform a network survey without sim card inserted, that function should be possible as mentioned in the datasheet, but when i perform the CSURV function, the module only says:

    AT#CSURV

     

    Network survey started …

    ERROR

     

    what do i have to change to enable this feature? Could you please give me the complete command set to make it work after power on? My Module is a GE-864 Quad.

     

    Thx,

    1. But you need to have antenna and signal, do you?

      Set AT+CMEE=2 before in the hope of a better error message.
