5.3.1.5 Query Received Signal Strength (QRSS[,<hex16>])
Format:
QRSS / QRSS,<hex16>
Use command QRSS to get the signal strength of the last communication with the
peer device. Use the signal strength to estimate the distance between the device and its
remote peer. In the case of multi-link connections, this command accepts an optional
parameter to get signal strength for a connection with a particular peer device. The
optional parameter expected in this scenario is the connection handle for the particular
connection.
The return value of command QRSS is the signal strength in dBm.
| Example: | QRSS |
// Check the signal strength of the last communication with peer device |
QRSS,0071 | // Check the signal strength with the device with connection handle 0071 | |
| Response: | RSSI
| // Signal strength reading |
Err | // Not connected |
