Unable to see nRF51822 on nRFGo St

[William Yap]

Hi all, I'm using MDBT40Nano from Raytac corporation with nRF51822 chipset. I tried to connect to my Segger J-Link Base but I'm not able to see the motherboard in nRFGo studio. I've done my setup according to the datasheet from Raytac. Can someone enlighten me please? Thanks in advance!

Have you made sure the board is powered and that you have installed drivers for the SEGGER J-Link programmer?
