hi, i am using sdk 10, with s120.

i want to advertise data on a single channel with frequency say (2426). is there any sample code or something, with which i can play with.

Hi,

If you meant BLE advertising you can look at Kristin's answer on this post: devzone.nordicsemi.com/.../

It's for S110 v8, but I have tested it in S110 and S130 v9 and it should be in SDK 10 too. You can look for ble_gap_adv_params_t --> ble_gap_adv_ch_mask_t in infocenter.nordicsemi.com/ for more information.

A tutorial on simple BLE advertising is also in devzone.nordicsemi.com/.../.

Hope it helps, FA

If you define:

static ble_gap_adv_params_t m_adv_params;
static ble_gap_adv_ch_mask_t ch_off;

Then in your advertising_init function you should have something like:

// Initialize advertising parameters (used when starting advertising).
    memset(&m_adv_params, 0, sizeof(m_adv_params));

    m_adv_params.type        = BLE_GAP_ADV_TYPE_ADV_NONCONN_IND;
    m_adv_params.interval    = NON_CONNECTABLE_ADV_INTERVAL;

You can now just add:

	ch_off.ch_37_off = 0;
	ch_off.ch_38_off = 1;
	ch_off.ch_39_off = 1;
	m_adv_params.channel_mask = ch_off;

This will only advertise in channel 37
