I recently got a smart meter device with BC66 chip but cannot communicate to device from server or vice versa. Manufacturer of device says I need to register the IMEI with local operator who upon consultation does not register the IMEI. How do I solve this?
hi,Maizs:
Can you execute the relevant query instructions through the serial port?If possible, I suggest you execute the following “AT Command” to check whether the device has registered with the network. According to your description so far, the most likely problem is that the device has not successfully registered with the network
AT+CFUN=0
AT+CFUN=1
AT+CEREG?
AT+COPS?
AT+QENG=0
AT+QENG=1
AT+CESQ
AT+QBAND?
After the query, I suggest you upload the results, and I will judge the relevant situation according to the results
