https://devzone.nordicsemi.com/f/nordic-q-a/15600/using-peripheral-examples-with-soft-device-bleI can run peripheral examples in SDK folder like GPIO, Timer, Scheduler ... but when I want to Add somethings like GPIO to peripheral_UART_ble or timer or scheduler It didn&#39;t work well and timer or GPIO doesn&#39;t work at all. this my code: consten-USTelligent Community 13Mon, 08 Aug 2016 15:21:10 GMThttps://devzone.nordicsemi.com/thread/59514?ContentTypeID=1Mon, 08 Aug 2016 15:21:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8636b9c1-3253-4b67-9992-ecca8990aaeaStefan Birnir Sverrisson<p>Hi Ali</p> <p>To see what is causing your reset or where the reset comes from, you can set up debugging like described on <a href="https://devzone.nordicsemi.com/question/60125/my-device-is-freezing-and-restarting/?answer=60126#post-id-60126">this thread</a> and <a href="https://devzone.nordicsemi.com/blogs/821/an-introduction-to-error-handling-in-nrf5-projects/">this thread</a>. For reference on how to use timer with softdevice, there is an <a href="https://github.com/NordicSemiconductor/nrf51-ADC-examples/blob/master/ble_app_uart_adc_scan_mode/main.c">example here</a>, see function adc_sampling_event_init.
