(This is the subject of another issue I have raised, logging does not work in the hrs freertos sdk 16 example.) I&#39;m trying to read pressure data from the BMP280 pressure sensor over I2C on the nRF52840 using freertosen-USTelligent Community 13Mon, 04 May 2020 15:15:49 GMThttps://devzone.nordicsemi.com/thread/247960?ContentTypeID=1Mon, 04 May 2020 15:15:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:410b129d-7cb5-4dd3-949d-04c640980602J&#248;rgen Holmefjord<p>Hi,</p> <p>Have you tried <a href="https://devzone.nordicsemi.com/f/nordic-q-a/10729/my-device-is-freezing-and-restarting">debugging the application</a>, to check if there are any error codes reported? You should be able to set breakpoints, but you cannot step the code after softdevice is enabled, as this will cause softdevice asserts. I would recommend to set breakpoint in the error handler, to check if any error codes are reported.</p> <p>Are you using any of the <a href="https://infocenter.nordicsemi.com/topic/sds_s132/SDS/s1xx/sd_resource_reqs/hw_block_interrupt_vector.html">blocked/restricted peripheral used by the softdevice</a> in the TWI part of the application?</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
