Bluetooth support is a missing feature on most Arnova G2 tablets, apart from the Arnova 7c G2 which has a different hardware.
Missing support in the device kernel and system can be added thru kernel modules, to make some external USB Bluetooth dongles work. Fenice57 already did that a while ago on his custom firmware for the Arnova 7 G2.
Bluetooth and GPS support on the Arnova G2 tablets with a custom firmwareWe have started to adapt our custom firmwares for the Arnova G2 tablets to include Bluetooth support on the devices that offer an USB Host feature. These firmwares should be published shortly, starting with the Arnova 10 G2.
Here is a video of an Arnova 10 G2 connected to a Royaltek Bluetooth GPS using a Daffodil Bluetooth USB dongle (ref. 06M)
Hardware requirementsThe setup to support Bluetooth on the Arnova tablets requires an USB Bluetooth dongle to be connected to the USB plug on the tablet, directly if the device has full size USB connector or using an USB Host cable.
USB Bluetooth dongle
The USB dongle must be based on a chipset made by CSR (Cambridge Silicon Radio, the company has actually been bought by Samsung two days ago), other chipsets are not supported at the moment.
We successfully tested the Daffodil 06M dongle below to be compatible.

USB Host cable, sometimes named USB OTG cable is used to connect the Bluetooth USB dongle (full size USB) to the tablet micro USB port. The Arnova 9 G2 and Arnova 10 G2 already have a full size USB Host connector and do not require the USB OTG cable.

Software setupAs you can see on our video, once you have loaded our custom firmware (to be published soon) you will need these two applications to use a Bluetooth GPS on your tablet. Both applications are available for free on Google Play.
You can then use any application that supports a GPS, including Google Maps.
Custom firmware updates with Bluetooth GPS support
LimitationsSo far we have only tested GPS support with this Bluetooth setup, we will update this article when we discover more possibilities.
The tablet does lock up when going into sleep mode when the Bluetooth / GPS module is being accessed.
