Hi I am having a bit of an issue which I hope you can help with.

I have an ME360 ecu which connects just fine via the serial to USB cable however I am now trying to move over to Bluetooth.

I have an Irxon bt578 v3 serial to Bluetooth adaptor which after some time I managed to change the BAUD rate to 115200 which i think is correct. The issue I am having is that realdash keeps cycling the connection so I cant get it to work.

Any ideas on what I need to do?

Cheers
