@rahulnrf From the schematics of that board, it looks like you should connect 3vo to VTG, and power the board from 5 V Vin, if programming using the SWD interface pads on the back.

Hi @Jørgen on the Adafruit circuit they do not have VDD should i connect VDD to VCC? I am interested in programming this learn.adafruit.com/.../25156

Yes, you can. You need an SWD debugger for that, and you can either use an nRF51/52-DK for that, or consider using a blackmagic probe - a much cheaper option:

Hi,

There is pads for the SWD interface (SWDIO/SWCLK) on the back of the Adafruit Feather Bluefruit LE board, making it possible to program it using an external debugger.

It seems there is also a DFU bootloader on the device, allowing you to update the firmware of the Bluefruit LE module OTA.

Best regards,

Jørgen

I believe SDK is incompatible with Arduino. It is better to use the SDK with other IDE such as CrossWorks, KEIL or Eclipse GCC.

If you wish, you can follow this blog to quickly get Eclipse running with nRF5x SDK.
