https://devzone.nordicsemi.com/f/nordic-q-a/1630/what-is-nrf2739Hi, I have nRFStartet Kit, nRF51822DK and EK. What is nRF2739? I am just following the setup section in nRF51SDK and it says to connect Master Emulator to PC. Is it referring to a piece of hardware? I have used PCA 10000 USB dongle before whileen-USTelligent Community 13Mon, 17 Feb 2014 12:57:08 GMThttps://devzone.nordicsemi.com/thread/7184?ContentTypeID=1Mon, 17 Feb 2014 12:57:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:78df7f5a-b3d8-4053-bc08-19f1b042c95fH&#229;kon Alseth<p>Hi,</p> <p>The nRF2739 is an older master control panel dongle that was based on the nRF8001. To use the MasterEmulator, you should flash the PCA10000 dongle with the mastercontrolpanel firmware, as described in the development kit user guide (page 13): <a href="https://www.nordicsemi.com/eng/nordic/download_resource/18799/4/72571168">www.nordicsemi.com/.../72571168</a></p> <p>Best regards Håkon</p><div style="clear:both;"></div>
