PanelDue - no signal from board
I have a problem with my paneldue running on atmel2560 board with the last version of repetier firmware (0.92.9). The panel is connected on TXD3 and RXD3 serial port of my board. With BLUETOOTH_SERIAL 3 and JSON_OUTPUT 1 the panel can drive the printer but don't receive any data from board like nozzle temp, files from SD...
I have do something wrong?
