RSSI for connections - help with setRSSIHandler()

Hi @Gordon, Hope I'm not taking too much of your bandwidth, but really appreciate the help as I explore the puck with some practical applications.

I've been in contact with the Nordic folks and the SoftDevice does support getting RSSI for each handle (connection). It would be great to have a way to access this on the puck. See below:

In order to measure the RSSI on a connected peripheral, you can use
the SoftDevice functions sd_ble_gap_rssi_get(),
sd_ble_gap_rssi_start() and sd_ble_gap_rssi_stop(). Provide the
conn_handle for the peripheral you want to get the RSSI from. You can
read more about these functions
here.
