advertising custom data in standard services

[Cyril Hruscak]

We need to send some custom data in advertising packet. Is it possible to use 'ble_advdata_service_data_t' with UUID of a standard service (e.g. battery service or device information service) or is it necessary to get our own 16-bit UUID for this purpose?

Regards, Cyril.

If you just need to send data in the advertising packet and don't need to create a service and characteristics you can also use the manufacturers specific data field allowed in the advertising packet. We do this to allow our mobile app to display information from our device without having to perform a connection.
