My second BLE board won't work

Post by jacobydavid »

I recently bought two nRF8001 Bluetooth Low Energy boards. My eventual use will involve reading from both at once, I hope. I have them soldered to headers and was able to get the first board talking to my Uno R2. I tried to connect the second board to other Arduinos and could not get it working. I then connected it back to the first, and found the second board doesn't function. If I take the first brakeout board off the breadboard and put in the second, it fails, and it works when I put it back.

What's the next step?

Could you post clear, detailed pictures of your board and the connections to it?

Picture of both. The one in the mini-breadboard is functioning.

Try reflowing the ground pins. Both look marginal. The problem with grounds is they are most often attached to a "ground plane" and suck heat from the connection faster than most making them harder to solder.
