https://devzone.nordicsemi.com/f/nordic-q-a/63669/heartbeat-example-hangingHi All, I am having a problem trying out one of the examples provided by Nordic. It is the &quot;ble_app_hrs_pca10056_s140_uart&quot; running on an nRF52840DK board. i programmed the S140 softdevice first and then compiled and downloaded the example softwareen-USTelligent Community 13Tue, 14 Jul 2020 08:45:59 GMThttps://devzone.nordicsemi.com/thread/259832?ContentTypeID=1Tue, 14 Jul 2020 08:45:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3f34a03d-c707-47b9-b770-dd50a23b46feSusheel Nuguru<p>How are you driving the UART from the PC side? Are you running the <a href="https://github.com/NordicSemiconductor/pc-ble-driver">pc-ble-driver</a> to drive the UART commands for the serialization?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/259633?ContentTypeID=1Mon, 13 Jul 2020 08:40:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7e931b5b-2190-4765-bc9e-3c16d5afec42Hugo Habicht<p>Hi,</p> <p>yes, thank you, I had assumed already that it should work. But it does not.</p> <p>Uart is connected to PC. What has the UART connection to do with the embedded side hanging?</p> <p>Can you answer ANY of my questions above?</p> <p>Kind Regards,</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/259627?ContentTypeID=1Mon, 13 Jul 2020 08:18:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:312562f7-41be-4950-b901-2ac1109f62d8Susheel Nuguru<p>If you are using serialization example then it should have worked out of the box.&nbsp;</p> <p>What is the configuration of the host device that is driving the UART? Is it anothre MCU or PC?</p><div style="clear:both;"></div>
