RE: Measure the length of the advertisement buffer

Hi,

Usually that happens because you entered the app_error_fault_handler(). If you are using SES, use the Debug configuration:

[quote user=""]How do I measure the length of the created advertisement buffer?[/quote]

As far as I know, there is no function to get the current length. If you try to add too much data, ble_advertising_init() will return NRF_ERROR_DATA_SIZE.

[quote user=""]This does not work. If I comment out the second UUID, then only it works.[/quote]

Try adding the UUIDs to the scan response data instead of advdata, snippet from advertising_init():

    init.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.srdata.uuids_complete.p_uuids  = m_adv_uuids;
