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.

The BT SIG specifies a set of standard UUID's for predefined set set of services and characteristics which is 16 bit.

But if we has to advertise a custom service or custom characteristic we have to use the 128bit custom UUID's for this.

For example of adding 128bit custom UUID ,refer to the example \nrf51822_v5.2.0\Board\nrf6310\device_firmware_updates\bootloader\

and have a look at the service ble_dfu.c
