https://devzone.nordicsemi.com/f/nordic-q-a/45282/how-to-program-nrf51822-prior-to-mounting-on-a-pcbHi, I just finished prototype using nrf51822. I programmed my part while it&#39;s mounted on my PCB. I am preparing for mass production. So I need to program the parts quickly before I mount the part. I bought a standalone socket for the part, How can Ien-USTelligent Community 13Mon, 25 Mar 2019 15:38:01 GMThttps://devzone.nordicsemi.com/thread/178171?ContentTypeID=1Mon, 25 Mar 2019 15:38:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d4e6a7d8-f765-49c4-b0b2-2d73613a7227Hung Bui<p>Which connector do you have on your socket board ?

Again, talk to your supplier, and your assembly house for suggestions/recommendations.</p> <p>Doing it manually in a socket is not a practical proposition!!</p> <p><span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f62e.svg" title="Open mouth">&#x1f62e;</span></p><div style="clear:both;"></div>
