Hi DJ,

For my omnibot, i am using a USB to Serial converter from SparkFun.

However, since the newest firmware update, i haven't been able to connect.
I've tried multiple converters but all fail...


Did you change anything?

I'd love to have it working next week so i can demonstrate it at the open house of our hackerspace:D

Allright so now i'm trying to update (over bluetooth of course) but i get this notification:

Code:

EZ-B reports EZ-B Firmware V15,7
Connected
Press the UPDATE button to start upgrade

Failed to load bootloader!
Have you selected the correct EZ-B COM port? Use the Help menu option to view the online help and watch a video demonstration.


I tried multiple times, different COM ports, different PC's, different bluetooth dongles....:(

The tutorial page explains that you have only 3-4 seconds to begin the upgrade after a connection.
