Frequency hopping with S132 v3

AmiguelS

Hello! I'd like to know if S132 v3 implements the frequency hopping scheme defined by BLE.

I've read some documentation on Gazell, but from what I understood, that is a completely different protocol, not a superset of BLE. I require BLE communication, so If my understanding is correct, Gazell is not an option.

    Of course it does implement frequency hopping. You don't have to think about such a low layers - this (among other features) is what softdevice is written for. You can however control which channels are used for advertisements.

    Yes, Gazell is something completely different.

    @wojtek I'm asking this because the behavior I'm seeing does not match what I expected to happen when frequency hopping is used. I may have the wrong idea though. I have two BLE devices and a strong Wi-Fi signal that overlaps some the of the BLE channels. What I observe is that sometimes I get huge interference from the Wi-Fi signal. This expected when the channels are overlapped. However, I expected the hopping to solve this issue by moving the BLE connection to a different channel, and that doesn't seem to be happening.
