Forum Post: RE: Carrier sense threshold setting for CC1101

Thanks a lot Martin for your quick reply.

I will try with changes in absolute threshold.

Just few questions,

1) How one can decide if to use relative threshold or absolute one? In our case we didn't know in what kind of environment RF boards will be placed.

2) Secondly in our communication network, one board(master) sends broadcast query to all other boards(slave). In reply all boards has to send packet using listen-before-talk policy. Again distance between master and salves is different i.e. one salve board might be close to master while other might be place farther. So RSSI of received signal will vary according to distance. In such cases how to decide CS threshold?
