The codes used to work few days back but now, it no longer works properly. After loading it for multiple times, it works only once.

The issue was with the softdevice application. I have used nrfjprog to retain the board.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/113652?ContentTypeID=1Wed, 20 Dec 2017 12:27:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:298a9db9-c489-4c59-8fe8-cd4ebb722dabJ&#248;rgen Holmefjord<p>Have you tried <a href="https://devzone.nordicsemi.com/question/60125/my-device-is-freezing-and-restarting/">debugging</a>, to see if any function calls return an error code? I suspect you are using some of <a href="https://github.com/Martinsbl/nrf5-mpu-examples">these</a> examples/code? Are you using SPI or TWI interface to the sensor? Please check the serial lines with a logic analyzer, to see if any data is transmitted/received.</p><div style="clear:both;"></div>
