So have you added code in main() to send characters and scope the tx pin? The "yes" answer above was too ambiguous!

yes. ble_app_uart work great in original view (when uart initialize and event handler locate in main.c). Ble_nus service works (I put some SEGGER mark in ble event). But uart event handler get nothing. in debug mode I can see that uart register has correct values (baudrate, pin numbers and etc). I use SDK14, softdevice 5

Can you send some characters in the main() and scope the tx pin?

What version of the SDK are you using? I have found strange behavior in v11.0 that is fixed in 14.0.

is it correct to define m_nus in my new ab_uart.h file:

BLE_NUS_DEF(m_nus);

Disabled. I change only Macros with pin number define to numbers themselves. (For not including pca10040.h). Other from Nordic ble_uart examples

In the original example was the flow control enabled or disabled?

I didn't try. But actually it's the example code that worked, I just extruded uart things into separate file for better readable

Does a lower baud rate like 57600 work?
