Hi,
Just to be sure the problem wasn’t on the android phone side, I established a connexion between my laptop and the bluetooth shield.
I mapped on /dev/rfcomm0 device my remote serial bluetooth shield and used minicom to transmit and receive data to/from /dev/ttyACM0 (attached to the serial port of my arduino UNO board). I configured both serial connections to 9600/8N1 without flow control. I still have the same problem, I can send data from my Arduino+bluetoothshield to my laptop but I can’t receive anything but dumb characters data on Arduino side.
Maybe there is some kind of hardware failure in my shield ? Does anyone from seedstudio have any idea ?
