4.8 RSSI Indication (PA3)

Use the RSSI indication pin (PA3) to indicate the quality of the link based on the RSSI level. The firmware activates the RSSI indication pin to indicate the deviation of the RSSI value from the predefined threshold level using the Set Event Indication Mask (EIM,<hex16>) command. The threshold level value can be set using the Set Link Quality Indication (SIL,<1/0>,<hex8>,<hex8>) command. Whenever the RSSI value goes beyond the threshold or goes below the weak RSSI limit, the firmware activates the event indication pin. Upon receiving the link quality event, use the Get Signal Strength (M)/(M,<hex16>) command to query the RSSI value for the specific connection. For more details, refer to 5.5.5 Set Event Indication Mask (EIM, <hex16>) and 5.5.7 Set Link Quality Indication (SIL,<1/0>, <hex8>, <hex8>).
