Serial port only works when debugging

When I test ble_app_uart here, RTT works, and nRF_LOG has the following settings:

The log is set to DEFERRED mode, and the LOG is processed in idle_state_handle(). idle_stat_handle_should look like the following for correct processing of the log (bug in ble_app_uart SDK15):

static void idle_state_handle(void)
{
    if (NRF_LOG_PROCESS() == false)
    {
        nrf_pwr_mgmt_run();
    }
}

Hello I have the same Problem. I use nRF52840, nRF5_SDK_15.0.0_a53641a, nrf5_SDK_for_Mesh_v2.0.1, Python3.5.2 64bit on linux mint 18 64bit. JLink_Linux_V633f_x86_64.

In aci_uart.py I set : def __init__(self, port, baudrate=115200, device_name=None, rtscts=False):

In Debug-mode it works:

Activating auto-logging. Current session state plus future input saved.
Filename       : log/18-178-8-46_interactive_session.log
Mode           : backup
Output logging : False
Raw input log : False

State          : active
Python 3.5.2 (default, Nov 23 2017, 16:37:01)

IPython 6.4.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: send(cmd.Echo("test"))

In [2]: 2018-06-27 08:46:48,476 - INFO - ttyACM0: {event: DeviceEchoRsp, data: {'data': bytearray(b'test')}}

But if i plug out plug-in the device i get :

In [2]: 2018-06-27 08:49:12,153 - INFO - ttyACM0: cmd Echo, timeout waiting for event

in examples/serial/include/sdk_config.h there are a lot of definitions with UART what exactly should i set to 1, if this is the problem ?

I'm new in this topic and my aim is to receive all the packets in the mesh and to send them to the host pc but first i whant to understand how to work with UART and this Board.

When the chip is running in debug mode, the HFCLK (HF crystal) is constantly running, could the problem be related to the HFCLK?

Yes the examples work fine, it's definitely something I ( or actually the previous developer did, as it has never worked right )

I see. Just for reference, does the UART logging work normally when using one of the examples in the SDK?

My custom app does not use sdk_config.h like the examples, the defines are set in the compiler definitions.

From SDK 12.0.0, the defines for using logging should be set in sdk_config.h, could you check the log settings in sdk_config.h?

oops, SDK 13, S132

If I program an example hex from nrfgo the serial port works fine. I tried the peripheral serial example and the multiprotocol example. I have other projects that work, and Ive been through the #defines.

This is very weird.

Which version of the SDK do you use? Do you see the same problem if you run one of our examples in the SDK?
