Updating Advertising Service Data

Good afternoon,

I'm running advertising with a uint16_t service data associated with a 16-bit service UUID.

I would like to update the service data regularly without the need to update the whole advertising package.

Is there a way to do this similarly to the flags_set() function in the BLE Advertising Module? When I try to accomplish it by recurring to "uint8_t * p_service_data = ble_advdata_parse(p_advertising->adv_data.adv_data.p_data, p_advertising->adv_data.adv_data.len, BLE_GAP_AD_TYPE_SERVICE_DATA)" I can never return the correct offset in the advertising data related to the Service Data field - it always returns 0 offset - and therefore can't access the actual Service Data to update it. Any suggestions to accomplish this?

Thank you,

João

  • Hi Martin,

    Thank you for your reply.

    I'm totally sure the advertising packet contains the ServiceData and it is working as expected. I'm updating the whole advertising data everytime I need to update the ServiceData and it works perfectly.

    Any queues what might be wrong?

    Thank you,

    João
