@TheSomeMan This code is meant to use together with the data format C5. The change adds Service UUID field into advertisement package. The end goal is that user application can filter for Bluetooth advertisements by Service UUID.

The code works by holding the desired service UUID and a flag to include the UUID in advertisement in a global variable in src/nrf5_sdk15_platform/communication/ruuvi_nrf5_sdk15_communication_ble_advertising.c. The ble_advdata_t structure will have the information Nordic SDK uses to build the final advertisement binary data, if the include UUID flag is included the UUID is included in the structure.

If the data cannot be encoded e.g. because user tries to include UUID with the original data format v5,

err_code |= ruuvi_nrf5_sdk15_to_ruuvi_error ( 
  ble_advdata_encode (&advdata, p_adv->data.adv_data.p_data,
                                         & (p_adv->data.adv_data.len)));

will return an error and advertisement contents are undefined - practically one or more fields are cut off, but nothing guarantees it.
