SOLVED Replace the wire with Bluetooth Module HC-05

[Laiwxn]

I have two HC-05 Buletooth module，I want to use them to replace the wire between the PanelDUE and the main board.Wow，It works very well.
But when I shutdown the mainboard,the paneldue still in standby mode，not the connecting mode.There is no heartbeat between The paneldue and the mainboard? Thanks.

@laiwxn can you Share the wiring and the Code.

You could try Resetting the paneldue with M999

@pcr the paneldue doesn't refresh the status automatically?

@Laiwxn, the connection times out and some point and get's back into connecting state. In standby tab although, the polling is interrupted.

Does this also happen in any other tab than setup screen?
