BlueNRG-LP: Get rssi value and channel of GATT connection

[rm87]

Hi,

Is it possible to get the used BLE data channel of the last connection interval?

I would like to more or less create a bar chart containing the 37 data channels and rssi values of the GATT connection for quality comparisons. 

Reading the rssi value with hci_read_rssi() works fine, but I don't know which channel the value belongs to ...

I know from other BLE chip manufacturers that this is possible by reading from a special register or memory address, but I could not find anything similar on the BlueNRG-LP module.

Thanks, BR
