Hello good people,
I have two identical puck.js v2. They both fully functional untill one of them stopped appear in the bluetooth dialog when connecting to web IDE, while I see second device in the dialog just fine.

I did a reset and a hard reset, when I insert a battery a red light blinks as expected I can even connect to this puck via USB serial and write code to it via web IDE. Only bluetooth is gone.

Any ideas how to investigate this problem further?

Hi - if you can connect by USB serial, please could you run:

• reset(1) - this will clear out any saved code
• NRF.getSecurityStatus().connected - this will return true if the Puck is connected to another device

The most likely situation is some other device is auto-connecting to the Puck - especially if you ever configured the Puck as a BLE HID device, some operating systems decide that once connected they will just keep connecting whenever they see the device - and that stops any other devices getting connected

Hi Gordon,
Thank you for your response.
This is make sense, but in my case NRF.getSecurityStatus().connected returned false.

My steps were:

1. Connect via USB
2. upload reset(1) + out put the NRF.getSecurityStatus().connected
3. disconnect from USB
4. insert the battery
5. search via bluetooth dialog in Chrome on my mac then search in the webble app on ios.

I also tried to run

var devices;
NRF.findDevices(function(d) {
  devices = d;
  console.log(devices);
}, 50000);

I started with 1000 then raised the time to find. No devices found. I expected it to find second Puck nearby.

Maybe I can somehow debug bluetooth module itself, run diagnostics, get more info?

I also tried to run NRF.findDevices

Wow, and nothing at all?

Please could you try and take a picture of the area where the aerial is? (the white thing on the blue module) I guess it's possible the aerial on the Puck got damaged?

Yep, empty array.

I guess it's possible the aerial on the Puck got damaged?

Could be, it happened after I was taking Puck in my jeans small pocket, but I can not detect any visual damages on the device.
Please see attached.

Thanks, that's a great photo!

Honestly, I think in that case it might be best to return it and swap it for a new one. It'd be the first time it's happened but it sounds like maybe something has gone wrong internally.

But first, just to be sure - if you do NRF.findDevices on the other Puck, how many devices does it see? A lot?

Thank you for this, where do I send it?

Yes, it found couple of devices around (same spot as a first one).
