Using the Heart Rate Collector example, the COM port is able to be opened but the NRF52 doesn&#39;t seem to respond.

For the nRF52832, you need to use&nbsp;connectivity_4.1.2_1m_with_s132_5.1.0.hex, where UART is the transport (then the onboard debugger on the DK acts as a USB-UART bridge).</p><div style="clear:both;"></div>
