I'm running out of ideas, I finally got a connection to a Bluetooth Barcode Scanner via SPP, but once I'm listening to the connection with
sudo cat /dev/rfcomm0
It's repeating the scanned code, everytime prepending some ^JJJ values:
^J^JJ^JJJJ^J^4000539103766
^J^JJ^JJJJ^J^4000539103766
^^J^JJ^JJJJ^J^4000539103766
^J^J^JJ^JJJJ^J^4000539103766
^^J^J^JJ^JJJJ^J^4000539103766
J^^J^J^JJ^JJJJ^J^4000539103766
and this continues, sometimes till it stop by itself or till I kill it.
Anyone has ever seen this?
