Hi,

I try to use nrf51 dougle as a sniffer.

My nrf51 dongle not show up when connected to PC, when press the reset button, it  only shows the boot-loader.   

I try to find "nRF5x-OB-JLink-IF" file, but I can't find it, I try to install "J-Link OB-SAM3U128-V2-NordicSemi 170724.bin ",but no enough memory (only 100k available).

Please tell me how to make it works,

Thanks,

Junp

Hi Junp, 

Could you take a screen shot of your bootloader drive ?

I tested using the .bin file here: https://devzone.nordicsemi.com/f/nordic-q-a/41192/where-to-download-j-link-ob-firmware-j-link-ob-sam3u128-v2-nordicsemi-170213-bin and it worked for me.
