Value range of nrf_modem_dect_phy_rx_params.rssi_level

Hello,

I have already implement the RSSI2 monitoring where I get the RSSI2 value with each successfully received packet via pcd-callback and its attached nrf_modem_dect_phy_pdc_event->rssi_2.

Its range is encoded from -140..1 dBm as defined/required by ETSI TS 103 636-2 V1.5.1 (2024-03) 8.3.3 RSSI-2 measurement report mapping (I have to convert it but thats no problem).

Now for my next rx-operation I want to set the expected rssi level from that previously received rssi2 value via nrf_modem_dect_phy_rx_params.rssi_level

But its range now is limited to -128 .. -1 dBm. That means I have to map the range -140 .. -129 dBm somehow.

Should I limit it to -128 or should I map that value to 0 (unknown)?

It would be nice if the nrf_modem_dect_phy_rx_params.rssi_level range would be conform to specification and therefore also would match the range of of measured rssi2 values.

 

Best regards
Rainer
