The LG-made Nexus 5 smartphone - one of Google's worst-kept secrets - has appeared on an official site suggesting that its launch is around the corner. The Bluetooth Special Interest Group is the organisation that approves devices if they want Bluetooth compatibility and a phone with what is believed to be the new Nexus's model number has been listed as being awarded certification.

From information gleaned from a leaked service manual, the model number of the device is widely understood to be LG-D821. That very same model number is noted in the Bluetooth SIG listing too. It's all starting to add up.

Needless to say, the phone has passed certification for Bluetooth 4.0. And LE too, we fully imagine, so it'll be compatible with smartwatches and the like.

In addition to the certification notice, other rumours suggest that we may see the phone sooner than many expected. CNET UK claims that "whispers around the campfire at Google Launchpad" say that the Android 4.4 KitKat-sporting Nexus 5 will be announced on 15 October. Next Tuesday.

That is also the Pocket-lint sources claim the HTC One max will be launching. Interesting times.
