Use command M or 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 M or QRSS is the signal strength in dBm.
