- Topic: DF-Bluetooth V3You Reply: @admin :Yes exactly !
Top sum up the problem : reading data from arduino is ok but sending data to arduino is the problem: it only works with softserial (i.e pins 2,3).
If I plug the RX on the Tx of the Dfrbluetooth everything work fine in echo but the Rx pin of arduino cannot read from the module... (I tried with arduino uno and duemilnove)

Best - Topic: DF-Bluetooth V3You Reply: This module is really bad for writing on it.
With the virtual serial it work almost but generate many errors on the arduino IDE like this :
java.io.IOException: Bad file descriptor in nativeDrain
at gnu.io.RXTXPort.nativeDrain(Native Method)
at
and so it is unusable in other applications as it draws java exceptions
When googling this you can see many other custormer having the same problem..... but it seems that nobody managed to solve it
I am very angry for losing so much time on it, I should buy a better BT shiled at first...
If someone find a solution please send it to me

@admins please include this info in the wiki to save customers time

Best - Topic: DF-Bluetooth V3You Reply: Hi guys
I got exactly the same problem as mikedeklerk :
everything is setup correctly (pingback from BT module and from arduino serial) but i cannot send data from computer to rx pin of arduino
I tried with arduino uno and duemilnove
I hope admins can come back with a solution for this!
On the wiki the example was to read from the arduino .... If tghis module cannot write to the arduino it should be stated clearly
i will try the softserial to see if it solve something...
