Hi all,

I've gotten stuck in safe mode and want to do a firmware upload so I can upload a good config.  V 3.0 VEMS so Bluetooth only and no serial port.

I keep running into a Comm error where the VEMS disconnects from my laptop as I try to use either the firmware upload wizard or if I skip that step and just try to upload firmware.  I've tried maybe 20 times, and I have occasionally been able to begin the firmware upload, but in those cases, I get to the end of the 8 or so minute process, and then VEMS disconnects with a "Port cannot open" error message and I'm back to square one.

Any ideas? 

I know there is a reset that can be done by jumping serial port pins, but I don't have a serial port.

Thanks

Where is the serial port Kamuto?  Do I need to open the VEMS box?  Externally I only have EC36 and EC18.  Thanks.

Bluetooth is built into the VEMS and I am communicating with a Levono laptop with built-in Bluetooth.  The VEMS has no external serial port, so no external Bluetooth adaptor.
