The Lumia devices are listed as having Low Energy Controller 
capabilities. This means they can act as a host to, and retrieve 
information from, Bluetooth low energy devices, and would be branded as 
"Bluetooth Smart Ready" devices.



Bluetooth hardware in the Lumia 920 and 820

The Bluetooth hardware in the Lumia 820 and 920 is part of the SoC 
(system-on-a-chip) provided by Qualcomm. The specific version of the 
Snapdragon S4 used in the Lumia devices is the MSM8960 (dual core 
version), clocked at 1.5GHz. Specific Bluetooth support is provided by 
the WCN3660 "Combo Chip", which also provides WiFi and FM radio 
functionality, and is a piece of companion silicon to the main central 
processing unit. Both Bluetooth 3.1 and Bluetooth 4.0 are supported by 
the WCN3660.

As an aside, thanks to the WCN3660 chipset, the WiFi functionality in 
Nokia's Lumia 820 and 920 devices is improved (compared to first 
generation Lumia devices), with support for WLAN IEEE 802.11 a/b/g/n 
(previously only b/g/n), WiFi Channel bonding and WiFi Direct. WiFi 
Direct provides a way for two devices to connect with each other without 
the need for a router, thus allowing direct data transfer with greatly 
reduced setup. WiFi Direct holds some intriguing possibilities for 
accessories (e.g. printers, media servers etc.), but at least initially 
is likely to be used for device to device transfer, with the set up 
facilitated by an NFC tap.

Incidentally the WCN3660 chipset also provides support for both FM 
transceiver (FM transmitter) and WiFi Display (streaming video) 
functionality, but Nokia is not, currently, using this in its Lumia 
devices. That seems a shame, especially in the case of FM transmitter, 
as it is a much loved feature on some on Nokia's Symbian devices and 
might help Nokia convert its existing customer to its new smartphone 
line up.
