How shall i define Service Data in BLE Scan Response Data ?

[Deep Patel]

This is the implemenatation spec for GATT server database (reader) firmware i am working on.

I have implemented advertisement packet using nRF Connect SDK latest.

Not sure how to declare 8-byte Service Data ? 

I have the 8-byte value with me.

This is how i have implemented

            uint8_t reader_serial_number[8] = some value;

            const struct bt_data service_sd[] =

            {

                BT_DATA_SVC_DATA16, 8, reader_serial_number

            };

But in the mobile app it shows like

Service Data: UUID: first two bytes (flipped bytes) and Data: Last 6 bytes correct order

Not sure what is wrong. Please explain and correct my implementation.

Thanks.

Are you configuring this in the ad data or scan response data? 

Looking at other samples the could be something like this

 uint8_t reader_serial_number[8] = some value;

            const struct bt_data service_sd[] =

            {

                BT_DATA_BYTES(BT_DATA_SVC_DATA16, 8, reader_serial_number);

            };
