I want to send data through UART
Did you end up figuring this out? I'm trying to do the same thing. I was able to establish a connection between the devices, using "examples/ble_central/ble_app_uart_c/", but haven't figured out how to send data from nrf52832 to HC-08.
That's the Nordic UART Service (NUS).
As the name suggests, it's a Nordic Proprietary service - so you'd have to implement it yourself at the HC-08 end...
EDIT
Alternatively, implement whatever proprietary service(s) the HC-08 has on the nRF end.
The point here being that there is no standard "UART-over-BLE" service defined by the Bluetooth SIG - so everyone does their own proprietary thing.
I thought that might be the case. Thank you for your help!
