Failed to connect to GVRET at that com port

[jannerboyjohn]

Guys, I have the ESP32 board connected to the laptop with the Windows driver for Silicon Labs installed to recognise the device and com port. Installed the ESP32RET_Updater firmware ok. I am at my wits end with this trying to get the device to connect to SavvyCan. I use the Serial Connection GVRET. Doesn't matter what I try just getting the following type of error and continously scrolling data in the device console window.
Connecting to GVRET Device!
Write to serial -> e7 e7 f1 c f1 6 f1 7 f1 1 f1 9

I must be missing something for this to work/connect? Hopefully I have ! :-)
Appreciate if someone could help me resolve this.

Cheers, John
