https://devzone.nordicsemi.com/f/nordic-q-a/109222/new-nrf52840-kit-softdevice-programmingI just ordered some new nRF52840 developmenmt kits, PCA10056 3.0.2. They behave very differently from the older kits that I have. They displayed 2 JLINK ports instead of one. I also have problems using nRFGo Studio to program the Softdevice.

You should only have 1 J-link port though.&nbsp;</p> [quote user=""]I also have problems using nRFGo Studio to program the Softdevice.[/quote] <p>nRF Go Studio is very outdated and has been deprecated for a while. Use nRF Connect Desktop instead.</p> [quote user=""]Where can I find the instructions to work with the latest development kits? The older kits are so much easier to set up.[/quote] <p><a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/boards/arm/nrf52840dk_nrf52840/doc/index.html">Here</a>,</p> <p>Also see the Quick start guide in nRF Connect Desktop application,</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
