Custom service vs UART service

[leonhart88]

Hi All,

A very general question here.  I understand that using pre-defined services like the battery service help standardize the way peripherals send data to the central device.  However, if I'm designing a device with a proprietary command structure, what is the benefit of using a custom service over a pre-defined UART service?  The latter is easier to get up and running from both the firmware as well as app point of view.

Thanks!

none.  UART service is a custom service with its own hardcoded uuid.  If you want a better one, see this blog about BLE custom service in a few lines of code.
