Hi.

Bluetooth Low Energy advertises by hopping between three different channels, that is channel 37, 38, and 39.

If you want to advertise on a single channel, you simply have to turn off two of the three channels.

You can find this in the infocenter here.

Example:

    ble_gap_adv_params_t adv_params;


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