Nokia has asked the FCC for permission to upgrade the Nokia Lumia 620 (RM-846) to Bluetooth Low Energy support via a software update. The update will bring support to the Bluetooth 4.0 chip which is already shipping with the handset, with only Bluetooth 3.0 features enabled.
Going along with this news is an interesting rumour – that Nokia is releasing a Bluetooth Low Energy Accessory in the form of the Nokia Treasure Tag WS2, which can be attached to keys, luggage or other items and which can then be located from your Windows Phone.
We certainly have no evidence for the veracity of that report, but Nokia is well known to support capabilities of their handsets with accessories, so it seems likely all the work to enable Bluetooth Low Energy support will probably also being some new accessories.
