https://devzone.nordicsemi.com/f/nordic-q-a/26721/custom-nrf52832-board-not-recieving-data-in-central-roleHello , I am using nrf52 Dk and nrf52832 custom board for testing ble communication. I am using ble_app_uart and ble_app_uart_c examples to test ble communication. In my custom board , I connected P0.6 to Rx of CP2102 and P0.8 to Tx of CP2102 for seeingen-USTelligent Community 13Sat, 11 Nov 2017 13:29:03 GMThttps://devzone.nordicsemi.com/thread/105083?ContentTypeID=1Sat, 11 Nov 2017 13:29:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1a628af8-26b7-4aec-94dc-64039f20cc13SaiTeja<p>My problem solved :) I coneected P0.7 of nrf52832 to RTS of CP2102 and P0.5 of nrf52832 to CTS of CP2102. I am able to see the logs in serial terminal.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/105080?ContentTypeID=1Fri, 10 Nov 2017 15:52:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a222b9dc-8863-48ce-98db-fa4ed708a25eSaiTeja<p>I am using CP2102 for debugging. I am flashing code into my custom board from nrf52DK. My custom board is in central role. And it is getting connected to peripheral. In my setup nrf52DK is in peripheral role. If I transmit data from central to peripheral, I am able to see the data received by peripheral in serial com port. But if I transmit data from peripheral to central I am unable to see data in the serial com port.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/105079?ContentTypeID=1Fri, 10 Nov 2017 13:26:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2f077d3f-3144-4a1d-b652-c3ffb46ea604Petter Myhre<p>RTT is Real Time Terminal. It is an alternative to doing printf over UART, using the debug interface instead. It is a Segger/J-Link feature.</p> <p>But have you done any debugging? Using a debugger, or by printing over UART? Does your application start? If it does, how far do you get in main()? Are successfully starting to scan? Are you receiving advertisements? Which SDK version and SoftDevice version are you using? Which example?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/105082?ContentTypeID=1Thu, 09 Nov 2017 05:55:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b2f77d62-3bb7-4d56-8c5e-a0976fc6e60eSaiTeja<p>Thank you for your time. My custom board contains only CP2102 and NRF52832. I am restricted to use this hardware for my application. What do mean by RTT? I am unaware of it. Can you please explain?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/105081?ContentTypeID=1Thu, 09 Nov 2017 03:46:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7387a8eb-a6dc-40be-a478-8c5cde86b40cMatt<p>Can you use RTT to debug this issue?</p><div style="clear:both;"></div>
