BLE advertisement

[Gilson]

Hello all,

I would like to understand advertisement packet more.

if I add the following to my packet my firmware causes nrf51822 to crash.

advdata.include_appearance      = true;
advdata.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]);
advdata.uuids_complete.p_uuids  = adv_uuids;

this only happens when I add manuf_specifi_data.

manuf_specific_data.data.p_data = (uint8_t *) m_beacon_info;
manuf_specific_data.data.size   = APP_BEACON_INFO_LENGTH;    // 6 bytes      
advdata.p_manuf_specific_data   = &manuf_specific_data;               // byte_array[6]

if I allow one or the other; it does not crash only when I add both.

So I must be exceeding the packet size when I add both. How can I calculate my discovery packet size?

what happens when advdata.include_appearance = true ?

Thanks, GM
