You have already declared several variables to store RSSI and LQI at the
receiving side (base station). The other thing you have to do is to put
those values into the payload of the message_t.
An example of defining your own message structure is:
#ifndef SAMPLEMSG_H_
#define SAMPLEMSG_H_
enum {
AM_SAMPLEMSG = 10
};
typedef nx_struct SampleMsg {
nx_uint8_t txpower; // Current tx power
nx_int8_t rssi; // RSSI
nx_uint8_t lqi; // LQI
} SampleMsg;
#endif
About the current tx, you have to get it at the sending side NOT the
receiving one.
Hope this helps.
