This is a confirmation of the behavior of the CYW43438 + STM32F412 when making a BLE connection to a smartphone.
The CYW43438 supports Bluetooth 5.1 and I thought that Channel Selection Algorithm #2 would be applied during the connection.
However, when I checked the sniffer, I found that Channel Selection Algorithm #1 was applied.
In CYW43438, would it be Channel Selection Algorithm #1?

Hi @hiko_4316286 ,
CYW43438 chip does not support CSA #2 feature of BT 5.0. Therefore you are seeing CSA #1 in the sniffer logs, which is correct.
