How to readout RSSI

[djdehaan]

I have created a nRF52840 BLE central communicating with several nRF52840 BLE sensors (servers) using Bluitfruit. I use my owh service, and a number of BLEClientCharacteristic to share various data. It all works nice and uses very little power!! My question is this: how do I read the Rssi signal level? I find various functions and a callback that seem to share Rssi, but this number is 0 all the time. How can I read RSSI?

I found a way using sd_ble_gap_rssi_start and sd_ble_gap_rssi_get, outside Bluefruit.
