Lego EV3 Bluetooth connected with DX-BT12 weirdly

I am working on Arduino demo application, try to connect Lego EV3 main brain brick to a dual-mode bluetooth BT12.

On EV3 brick, the operations (searching and pairing) are going well, but after I click "connect", it shows "connected" and my bluetooth module is keeping flashing its red LED light, which means not connected well.

I tried to use another bluetooth module HC-05 which is a bluetooth 2.0 module. The code is working fine.

I am not sure if it's because of the dual modes of bluetooth.

The default channel for DX-BT12 is 3, not 1 which has been set in RN-42 or HC-06. You can get access to BT12 by typing :

sudo rfcomm bind 0 XX:XX:XX:XX:XX:XX 3

and 

cat /dev/rfcomm0
