RE: Restart Advertising after changing device name

Thankyou, calling sd_ble_gap_adv_set_configure with advdata non-null was the key.

I was using a mix of example code and sdk calls to reset / restart.

The example code initialise function called set_configure without the adv data. Calling ble_advertising_start, after initialising again, makes another call to sd_ble_gap_adv_set_configure with the advdata pointer passed correctly

void ble_app_restart_advertising(void)
{
    // Stop
    bool erase_bonds = false;
    uint32_t err_code = sd_ble_gap_adv_stop(m_advertising.adv_handle);
    NRF_LOG_INFO("Stopping advertising");

    // Re-init
    advertising_init();

    ble_app_advertising_start(&erase_bonds);

    NRF_LOG_INFO("Starting advertising");
}

Hi,

You will also need to update the advertisement data. This can be done using the Softdevice call: sd_ble_gap_adv_set_configure

Or if you use the sdk advertisement module by using the SDK function ble_advertising_advdata_update
