https://devzone.nordicsemi.com/f/nordic-q-a/30436/programming-custom-board-from-ebayHello, I have recently bought a couple of boards from eBay that come with the nRF58232: https://www.ebay.com/itm/Wireless-Bluetooth-Transceiver-Module-NRF52832-Development-Board-1-7V-to-3-6V/332128757335?epid=851397440&amp;hash=item4d546aa657:g:VUgAAOSwhf1Zm93oen-USTelligent Community 13Mon, 12 Feb 2018 14:24:59 GMThttps://devzone.nordicsemi.com/thread/120586?ContentTypeID=1Mon, 12 Feb 2018 14:24:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3b386965-019c-4325-835a-122475669712AmbystomaLabs<p>The FTDI cable does USB to UART communications and will not work for programming an nRF52832. The nRF uses SWD communications for programming. If you have SWD you can erase the chip and load any code you wish.</p> <p>The only way for uart programming to work is if the board has some sort of custom uart bootloader on it. This is not standard.&nbsp; You would need to ask the board manufacturer specifics about how they configured it.</p><div style="clear:both;"></div>
