Channel Selection Algorithm S132 SoftDevice

[Dresse]

Hi Nordic,

I am working on NRF52 DK, with the example program ble_app_interactive, SoftDevice S132. I am trying to connect to peripheral board, but I can't establish an connection. It gives me the error code 0x3E. I think i have found the problem, the Channel Selection Algorithm is #2, which I believe comes from the SoftDevice S132 please correct me if i'm wrong. But the device I am trying to connect to, can't handle this Channel Selection Algorithm. It can only handle #1. Can i change it back to #1? Or are the any other way to work around this?

Best Regards Andreas Hansen

I think i have misunderstood Channel Selection Algorithm. After reading about it in Bluetooth Core Specification, and this other topic on DevZone https://devzone.nordicsemi.com/f/nordic-q-a/27479/chsel-algorithm. If one of the devices has ChSel field set to 0, then Channel Selection Algorithm #1 shall be used.
