How to get signal strength and quality of a BLE connection?

Firmware

Hi,
is there a way to get the signal strength and quality of an ongoing BLE connection?

I see that one can get the RSSI (The signal strength of the advertising message) when scanning, but is there a way to update this value after the connection is established?

Thanks!

PS: since I cannot find any reference for signal quality, I'm thinking that this metric does not exist on BLE.

There is no way to get the RSSI of BLE connection that is already open. It's only available during scan.

There in no qual, which is typically a cellular data thing. It's based on the signal-to-noise ratio, so in theory it could exist for BLE, but the BLE hardware doesn't measure it.
