When I first got the nRF51-DK board... I was able to see this board on nRFgo. I then added the s130 hex file to it.. Since then when I connect this board, it does not show up in the nRFgo.
I see the device as a D: mbed -drive in the windows explorer.
So, Why am I not seeing the device on the nRFgo?
Whey is the purpose of chaging the softdevice? do I need to do this everytime? I have added this as softdevice first time.
