Hello,

how can I set the RSSI threshold? It is always set to -96 on my Device Control panel (RSSI Offset: 96).

Hi,

the number 96 is the RSSI offset and is not a threshold. The value in the RSSI registers is a raw value and to get the correct level of the applied signal a offset has to be added. For CC1120 this number is 101, the current version of Studio (v1.5.0) has a bug here, this will be fixed in v1.6.0 out next week.

In the AGC_CS_THR it is possible to set a carrier sense threshold, other threshold is also possible. Could you please elaborate what you are looking for?

I wish to accomplish maximum sensitivity in transparent serial mode.

As a starting point use the 1.2kbps settings from Studio given that you are going to work with low datarates.
