5.5 Verify the Received Signal Strength
The Fastrack M1306B establishes a call only if the received signal is sufficiently
strong.
To verify the received signal strength, do the following operations:
• Using a communication software such as Hyperterminal, enter the AT
command
AT+CSQ.
The response returned has the following format:
+CSQ: <rssi>,<ber> with:
•
<rssi> = received signal strength indication,
•
<ber> = channel bit error rate.
• Verify the
<rssi> value returned using the Table 5 below.
Table 5: Values of received signal strength
