ble_app_buttonless_dfu reset on pin interrupt

[Rajneesh]

Hello Nordic team

I am working on nRF52832 Dk, SDK v15.2, example "ble_app_buttonless_dfu".

Following code snippets is the GPIO configuration for pin interrupt:

ret_code_t err_code;

err_code = nrf_drv_gpiote_init();
APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_LOTOHI(true);
in_config.sense = NRF_GPIOTE_POLARITY_LOTOHI;

err_code = nrf_drv_gpiote_in_init(ACCEL_INT_PIN, &in_config, in_pin_handler);
APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_event_enable(ACCEL_INT_PIN, true);

ble_app_buttonless_dfu working correctly (OTA update). I have added support for accelerometer when any pin interrupt received on gpio pin as soon as board get reseted and print following message on serial console:

<warning> app: System reset

Any suggestion why board reset after received GPIO interrupt?

Any help will be appreciated.

Hi, 

Please try to debug that. You may want to follow this guide and look for the error code and which function causing the assertion.

Hi Hung, Thanks for the response. Here is the detail of error. devzone.nordicsemi.com/.../nrf52-sdkv15-2-nrf_breakpoint_cond-strange-behavior

[Hung Bui]

Please avoid creating duplication cases for same error. 

Please find the line number and the file name when you have error_code = 8. You may want to define "DEBUG" in the preprocessor symbols as mentioned in the guide.

Hi Hung

app_timer_start return error in APP_ERROR_CHECK(err_code);

[Hung Bui]

Okey, so if the error_code is 0x08 then it means  :NRF_ERROR_INVALID_STATE : If the application timer module has not been initialized or the timer has not been created.

Please make sure you have initialize the timer.
