[bull]

I use it. nRF52832 PCA10040 Vesion12.2.0

I am working on the ble_app_uart example as a base.

Just in case, is it possible to change the UUID?

And, what can be the addition of HID UUID?

You want to change the 128 bit UUID used for Nordic UART Service? You can, but why? I don't understand what you mean by "And, what can be the addition of HID UUID?". Please try to explain.
