Hello,

Yes, it is possible to advertise only on one channel in NCS.. You can disable advertising on a specific channel using the following options when you set the advertising parameters..

  /** Disable advertising on channel index 37. */
    BT_LE_ADV_OPT_DISABLE_CHAN_37 = BIT(15),
 
    /** Disable advertising on channel index 38. */
    BT_LE_ADV_OPT_DISABLE_CHAN_38 = BIT(16),
 
    /** Disable advertising on channel index 39. */
    BT_LE_ADV_OPT_DISABLE_CHAN_39 = BIT(17),

For example, if you want to advertise only on channel 37, you can do the following:

struct bt_le_adv_param *my_adv_param =
    BT_LE_ADV_PARAM(

            BT_LE_ADV_OPT_CONNECTABLE,

            BT_GAP_ADV_FAST_INT_MIN_2,
            BT_GAP_ADV_FAST_INT_MAX_2,
            NULL);
 
    my_adv_param->options |= BT_LE_ADV_OPT_DISABLE_CHAN_38;
    my_adv_param->options |= BT_LE_ADV_OPT_DISABLE_CHAN_39;
 
    err = bt_le_adv_start(my_adv_param, ad, ARRAY_SIZE(ad), sd, ARRAY_SIZE(sd));

Hope this helps.

Regards,

Swathy

Thanks Swathy for the confirmation.

I assume, scanning on one channel is not possible but sending advertisements packets on only one channel is possible, right?

Hello,

Sorry, but it is not possible to scan only one channel.
