To transfer the error code to the PC, you can use the log module. If UART is already in use, you should use RTT instead. RTT is also supported by the LOG module.

The main function is to advertise the beacon in general and perform the serial communication when the uart connection is made, and advertise the beacon again after the communication is finished. Probably it is caused by a part of APP_ERROR_CHECK (err_code2) code. Currently, it is not observed that the beacon is terminated because it has been completely modified. I am deeply grateful for your advice. .. How can I leave an error number? In case uart connection or usb connection is not available, how can I get error number to pc when error occurs? Do you know a good way?

What else than advertising does the device do? If it is only advertising, it shouldn't be any difference between being in the field and debugging at a desk. An alternative to debug mode is logging over UART.

Approximately, how often does the error occur? I'm a little confused: "It happens very rarely..... It is hard to find in debug mode...... " and "We are constantly observing that beacons are going down. ".

It happens very rarely..... It is hard to find in debug mode......
This is an error that occurs when using the actual field ... Debugging is hard to observe.... However, as of now, it is assumed that ..... at power_manage(void) function .... APP_ERROR_HANDLER(err_code); It is estimated that the correction has been made because there is less complementary correction. ... APP_ERROR_HANDLER(err_code); so.... We are constantly observing that beacons are going down. Thank you very much for your response.

If you run the chip in debug mode and set a breakpoint in the error handler, you can find the error code and use the callstack to find where the error occurred.

I have not found it yet.... Because sometimes it happens ...
so I set it to reset when an unexpected error is detected.

Which error code do you get?

thanks answers about my question..... my error handler code is below.....

// Build advertising data struct to pass into @ref ble_advertising_init. memset(&advdata, 0, sizeof(advdata)); advdata.name_type = BLE_ADVDATA_FULL_NAME; advdata.include_appearance = false; // advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE; advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE; // sleep모드 끄기

memset(&scanrsp, 0, sizeof(scanrsp)); scanrsp.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]); scanrsp.uuids_complete.p_uuids = m_adv_uuids;

ble_adv_modes_config_t options = {0}; options.ble_adv_fast_enabled = BLE_ADV_FAST_ENABLED; options.ble_adv_fast_interval = APP_ADV_INTERVAL; options.ble_adv_fast_timeout = APP_ADV_TIMEOUT_IN_SECONDS;

err_code = ble_advertising_init(&advdata, &scanrsp, &options, on_adv_evt, NULL);

but form time to time.... occasionally....... sometimes...... just stop beacon advertisement.............

Did you change advdata.flags in advertising_init() to BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE instead of BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE ?

Unfortunately, there is no way for the application to check if a device is currently advertising. If the advertising timeout is set to '0', there is no advertising timeout. It therefore has to be another reason why the device stop advertising.

Does your device at some point gets connected to another device?

How do you do error handling? If an error is caught by APP_ERROR_CHECK() and the "DEBUG" flag is set, the error handler will go into a infinite loop.
