Sending data continuously uart_example nrf52832 sdk 15.0.0 SD140

Helo,
Im trying to sending data from sensor between two nrf52832, SDK 15.0.0 SoftDevice S140 on both.
Im using uart central and peripheral examples on transmiter and receiver.
I set timer to read data from sensor every 20 ms and i want to send data using
ble_nus_data_send(&m_nus, accelvalue, &length, m_conn_handle);
Devices pairing very well and sending data only once with first timer event.
How can i send this frame every 20 ms continuously.

EDIT:

I think the problem is with that i dont have any hardware uart connected to my custom board and after sending one connection interval nfr reset ;/ 

I need to find and turn off no hardware uart error handler and turn it off, but how?

I know i need to wait for BLE_EVT_TX_COMPLETE  event but i comlitely dont know where and how check it...

It may be because my custom board have no hardware uart connected?

If your nrf resets it is probably because one of your function returns an error. It is then possible that your code ends up in an error handler that resets your code. You can debug this like shown here.

If this is the case, you can find the origin of the error and the error code. Then look at the documentation of the function that returned the error, and see if it makes any sense to you.
