I finally found a compatible, low price, worldwide available bluetooth dongle. The brand name is “Pluscom”, it’s quite unknown, and the model name is “BT-20″. The chip inside this dongle is a CSR Bluecore4-rom, and what’s even more surprising is that it’s written “CSR BC4″ on the product package.
This dongle is available on ebay: link. The price is good and the seller is in the UK, which should provide a faster delivery than China to people living in the EU or the US. No longer available 
The shape of this dongle is exactly the same than my Peabird PEAB-BT-SM04C-100M (CSR Bluecore4-rom). It’s not a very common shape for bluetooth dongles, so that I think it’s highly possible that these dongles come from the same factory.
I want to use a script (bash, Perl, Python, or anything) to send keyboard keypress events to the Sixemugui. I have tried xdotool and the Python module virtkey, but Sixemugui ignores my simulated keyevents. I am using Ubuntu, and the Sixemugui works fine with physical button presses. Do you know how I can programmatically create keyevents that Sixemugui will respond to?
Did you tried the macro tool?
I think xdotool generates events for the keyboard named "Virtual core XTEST keyboard". You have to configure mapping for events from this virtual device.
Yes, I tried the macro tool, but my understanding is that I still have to press a physical key to start the macro, so that wasn't what I was looking for.
However, your suggestion to configure mapping from the virtual device worked perfectly. Thank you for your quick response!
Hi. This GIMX is wery interesting! But as I’m trying to find a suitable bluetooth dongle, I opened the ebay link in this post. Is 142$ (USD) really a good price for a USB bluetooth dongle??
Found it here: http://www.amazon.co.uk/Quality-Bluetooth-Wireless-Receiver-Adapter/dp/B005FVZZV8/ref=lh_ni_t
for only 5.91USD
A SmALL difference in price there.. 
It seems the seller doesn’t want to sell this dongle anymore…
