Thingy:52 BLE advertising data

Hello

I'm trying to use the NordicThingy52 sample app to connect to a 3rd party (micropython) device posing as a thingy device.

So far I'm not even getting past the scan filter:

if( contains( result.getServiceUuids(), _profileManager.THINGY_CONFIGURATION_SERVICE ) ) {
    broadcastScanResult( result );
}

I have 3 entries in my BLE advertising packets:

That is: flags, service UUID (128 bit) and short-name.

Still the device is not recognized by the NordigThingy52 app (Devices: 0/0).

Any help as to how the thingy-device advertises or how the watch parses the advertising data would be greatly appreciated.

I have a simple app that shows the data the way CIQ sees it. I'm thinking that the UUID isn't the same as an actual thingy52:

The "thing17" screen shot is what I see with a thingy52, and if you press select, you can see the raw data in the packet.

nRFConnect on a phone can also be helpful.

Thanks for the pointer to the BleScan app - it's really useful.

Turns out the NordicThingy52 sample actually looks for another service than the one it connects to:

THINGY_CONFIGURATION_SERVICE vs. THINGY_ENVIRONMENTAL_SERVICE

Now it hangs on the pairing - but I am a bit further I guess.

Thanks

Yes, the thingy52 advertises the config service - in addition to the env services there are a few more. See

for more details.

If you are building your own sensor, you may want to use your own range of UUIDs - that's what I've done with my raspberry pi based stuff.

Also, here's the breakout from the summit about BLE in general:
