[bruce]

I Want Control ibeacon Channel 37,38,39 Hope only one channel 37 or channel 38 or channel 39 What should I do

With the newest SDK and the sd:v8.0.0, use the sd_ble_gap_adv_start function, set

    adv_params.channel_mask.ch_37_off = 1;
    adv_params.channel_mask.ch_38_off = 1;

Then nrf51822 will only adv using channel 39.
