RSSI Reading
The RSSI (Received Strength Signal Indicator) gives an indication for the
received power level.
It could be accessed with AT commands.
The RSSI level is only an indication. Use this level with care due to the
dispersion between components.
The schema above could be modified from one to another product. The
operating temperature could also have an impact on these dispersions.
The RSSI level could also indicate the potential presence of jammer in the
used channel.
The RSSI is a necessary but not sufficient condition to obtain a
correct reception.
Transceiver operating mode
Two operating modes are available :
Command mode (usage of AT commands)
