RTOS/CC1310: CC1310 Wake on RX "CarrierSenseMode_RSSI" mode RSSI threshold

Part Number: CC1310

Tool/software: TI-RTOS

Hello,

I have used "rfWakeOnRadioRx" project. 

I have changed the "carrier sense mode" from "CarrierSenseMode_RSSIandPQT" to "CarrierSenseMode_RSSI" mode.

The default RSSI threshold in this project is -111 dBm. So if i am using only RSSI sense wake up only then is it safe to keep -111 dBm threshold 

or shall we keep it better than that like -100 dBm.  

My concern is at -111 dBm receiver shouldn't wake up due to any other noise. 

Regards,

  • When using only RSSI compared to using both RSSI and PQT you will experience to stay in RX more often due to noise (meaning an increase in current consumption). To avoid this, you can increase the threshold like you suggest. The drawback is that you then also reduces the sensitivity. Setting the threshold to -100 dBm means in practice to reduce the sensitivity to -100, since you will exit RX for all packets with a lower signal strength than the threshold. In other words, what you should set the threshold to depends on what is most important to you; low current consumption or good sensitivity (long range).
