https://devzone.nordicsemi.com/f/nordic-q-a/13961/nrf51822-3rd-party-module-programmingHello everyone, We want to develop a wearable product using nRF51822, we found there are 3rd party module mentioned on the Nordic Semiconductor. And there are some development kit available on the website for nRF51822 , nRF51- Dongle and nRF51-DK.en-USTelligent Community 13Thu, 19 May 2016 12:26:25 GMThttps://devzone.nordicsemi.com/thread/53322?ContentTypeID=1Thu, 19 May 2016 12:26:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8ebe9738-951a-4723-b939-e8e507719152Ole Bauck<p>Hi,</p> <p>The nRF51 DK has an on board debugger/programmer that can be used to program other chips as long as the debug interface is accessible. The nRF51 dongle does not have any debugger/programmer and can not be used for this purpose. See for example <a href="https://devzone.nordicsemi.com/blogs/803/programming-and-debugging-custom-nrf5x-devices/">this blog post</a> on how to program custom nRF5x devices.</p> <p>Ole</p><div style="clear:both;"></div>
