GL61x0 Product Technical
Specification and User Guide
Communicating with the GL61x0
8.2. Verifying the Received Signal Strength
The GL61x0 only establishes a call if the received signal strength is strong enough. Using
communication software such as HyperTerminal, enter AT+CSQ to check the received signal
strength. The response returned will follow the format +CSQ: <rssi>, <ber>
where: <rssi> = received signal strength indication, and <ber> = channel bit error rate.
Refer to the table below for the description of the <rssi> values returned.
Table 30. <rssi> Value Description
<rssi> Value
Description
0 – 10
Received signal strength is insufficient.
11 – 31
Received signal strength is sufficient.
32 – 98
Not defined.
99
No measure available.
Refer to document [7] Firmware 7.42 AT Commands Manual (Sierra Wireless Software Suite 2.32) for
more information regarding the AT+CSQ AT Command.
8.3. Verifying the Network Registration
To check the network registration, make sure that a valid SIM card has been properly inserted into the
GL61x0.
Note: When using the GL6100 with Embedded SIM, ensure that the device has been registered by the
network provider.
Using a communication software such as HyperTerminal, enter AT+CREG? to verify the network
registration of the GL61x0. Refer to the table below for the list of main responses returned.
Table 31. AT+CREG Main Reponses
AT+CREG Response
Description
+CREG: 0,0
Not registered.
+CREG: 0,1
Registered on the home network.
+CREG: 0,5
Registered on a roaming network.
If the GL61x0 is not registered on the network, do the following:
Check the connection between the GL61x0 and the antenna.
Verify the signal strength to determine the received signal strength (refer to section
8.2Verifying the Received Signal Strength).
Refer to document [7] Firmware 7.42 AT Commands Manual (Sierra Wireless Software Suite 2.32) for
more information regarding the AT+CREG AT Command, and other AT commands relating to
network registration in GPRS mode.
