You can solve this problem by following this link (<a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.EngB.errata%2Fanomaly_832_89.html">http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.EngB.errata%2Fanomaly_832_89.html)</a>.</p> <p></p> <p>I solve this problem by uniniting TWI after the communication finish. Like this;</p> <p>nrf_drv_twi_uninit(&amp;m_twi);<br /> *(volatile uint32_t *)0x40003FFC = 0;<br /> *(volatile uint32_t *)0x40003FFC;<br /> *(volatile uint32_t *)0x40003FFC = 1;&nbsp;</p><div style="clear:both;"></div>
