I already commented on a thread about this topic in the YUN-section (http://forum.arduino.cc/index.php?topic=219682.0 ), but somehow no one over there is interested in making a bluetooth 4.0 usb-module work properly with the Yun. Thats why I'd like to ask you guys.
I've bought this module (IOGEAR GBU521W6): http://www.amazon.de/gp/product/B007ZT2AXE/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
..because: 1. its compatible with the Yun, as you can read on this site: http://fibasile.github.io/arduino-yun-ibeacon.html 2. I want more than one bluetooth device connected to the yun (!!) +I want to free sketch space (by using the linino)+ free pins on my YUN (currently occupied by my HC-05 on the Yun; Connection to a UNO which also has a HC-05) + save space and money (imagine 3-4 hc-05 hooked up to the yun)+ ... so that dongle would be perfect
I installed it this way: http://wiki.openwrt.org/doc/howto/usb.bluetooth
And it really works up to a certain degree: hcitools and hciconfig inquire/scan properly, find other devices etc., my android phone pairs with it (not the other way round...the phone has to start the pairing, else it won't work)......
But I don't know how to pair the HC-05 to it..., because the connection command
hcitools cc XX:XX:XX:XX:XX doesn't work... it always returns nothing with the HC-05... and it always runs into the timeout with my phone...
I already set a HC-05 to "slave" and to 9600,1,0 and followed the steps to connect a dongle as it is described here (for raspberry): http://myraspberryandme.wordpress.com/2013/11/20/bluetooth-serial-communication-with-hc-05/
I thought it might be because of the passkey so I created the necessary pincode-file with
echo "xx:xx:xx:xx:xx 1234" >> /var/lib/bluetooth/yy:yy:yy:yy:yy:yy/pincodes...but still no luck
