BLE Generic UART service, is there?

[djqtsg]

For conventional Bluetooth, if two devices are connected, we can send and receive text/bytes to and from each other. It is generic since the two devices can be from different vendor.

For BLE, if we run nRF UART application on one device, the other one must also run the same application so that we can send and receive from each other. Is there a generic UART service defined in BLE? If no, why is that?

[RK]

No there isn't a generic UART service defined in BLE because the Bluetooth SIG hasn't defined one. They don't really go for generic services, they specify targetted services and profiles aimed at specific well-defined functions.

Thx, got it.
