Extract Channel List Info

[danbujak]

Is it possible to somehow get access to the channel hopping data from BLE. We're trying to trace some interference from an external device, and want to be able to see when and how the soft device stops using certain channels when interference is present.

You can use sd_ble_opt_get() with the option ID BLE_GAP_OPT_CH_MAP and a parameter of type ble_gap_opt_ch_map_t to fetch the current channel map. I can't find an event generated when it changes however, so you'd have to poll it on an occasional basis to get the current one.
