Troubleshooting

The nRF8002 on the SoC module (nRF2748) does not respond when I try to contact it. What has 
happened?

Verify that the jumper 

JP5

 is connected.

LED D0 on the µBlue

 

Master Emulator (nRF2739) does not light up when I plug in the USB cable. 

What has happened?

Verify that the Master Emulator (nRF2739) has been plugged into a USB port on your computer.
