Getting matched RSSI & Radio Frequency pairs

[jcondon]

Greetings,

I am trying to get the frequency/channel matched with RSSI values using S110. Is there a way to pull it through the softdevice functions?

If not, can I pull the value from NRF_RADIO->FREQUENCY? When/where would be the best time/place to perform that call so make sure it was used for the RSSI value returned in the BLE_GAP_EVT_RSSI_CHANGED event?

Thanks!

unfortunately there is no way you can have this mapping. Softdevice or chip do not have this info about the sampled signal channel as it does not save this.

The application will not own CPU at the time the chip is sampling the incoming signal, so it there is nowhere that you can sniff NRF_RADIO->FREQUENCY when the sample is being taken.

maybe, if this is not just for benchmarking/calculations and is applicable for a real use case. What exactly are you trying to achieve with this? your explanation will help me try to convince the softdevice team of its need.
