i just recived my JY-MCU V1.06 but i can't figure out how to pair it with the phone...I load the sketch (with the TX,RX pin disconected) search it with the phone pair it (1234) then open the app and it say Unable to connect device" , and Led wont get solid
I guess it is not compatible with the V1.06 
....any ideeas
