Assuming you can connect you could try:
```
NRF.on('connect', function(addr) { LED3.set(); });
NRF.on('disconnect', function(addr) { LED3.reset(); });
```
Just to rule it out - it'll light the blue LED if some other device tries to connect to it after the code is uploaded.

If this continues with new batteries then you can send it back if you want and I'll take a look at it?
