Table 10, Wi.232FHSS Reset Circuit Specifications
3.6.6. Receive Signal Strength Indication (RSSI)
The RSSI pin contains an analog voltage proportional to the signal strength present on the channel at the
time. In normal operation, the module is hopping rapidly from channel to channel looking for valid data. In
this case, the RSSI value does not provide much in the way of useful information. However, it can be used to
keep a module awake. For instance, if you are preparing to put the module to sleep, you may sample the
RSSI pin to determine if it is processing a packet.
The Wi.232FHSS-250-R module has an internal, digital RSSI indication of
good packet
state of the packet engine.
RSSI level is dependent on the power of the signal received at the antenna port and the mode the LNA is in.
