Signal strength and quality

If the mobile device is already registered on the network. The following AT commands can
be used to query the received signal strength and quality, thus giving an indication of the
reliability of the wireless link.

AT+CESQ
Assuming that the module is not connected to the antenna or the network cannot be
covered at all, there are:

AT+CESQ

+ CESQ: 99,99,255,255,255,255 // In this case, the module cannot be connected to the network

OK

Now, the antenna is connected to the module and the network coverage reaches the
current position. Execute the above AT command again:

AT+CESQ

+ CESQ: 17,99,255,255,26,87 // 17 is the received signal strength indicator

OK

Module registration network status query

Execute the following AT command to verify whether the module has been registered on
the EPS network using E-UTRAN method:

AT+CEREG?

AT+CEREG? // Verify that the module is registered

+ CEREG: 0,1 // registered

OK

Now, suppose there is no signal (the module is not connected to the antenna) and
execute this command again:

AT+CEREG?

+ CEREG: 0,3 // In this case, the module cannot be connected to the network

OK

AT+CEREG=2 // Enable EPS network registration and position information to report actively, the results are as
follows:

+ CEREG: <stat> [, [<tac>], [<ci>], [<AcT>]]
