Usb-≫Serial Adapter

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?

Hey Niek,

Is the LED on the board pulsating?

If not, i think i know what it may be. Gimmie a few hours and i'll send you something to try.

No, it's solid.

When i mess around a bit (swapping bluetooth with USB) and it starts pulsating THEN it works but once i restart it wont pulsate again:(


Thanks in advance:D

Hey DJ,

While we are on this subject (I hope you get your TTL) going Niek, does EZB respond to any AT commands to self check to see if the COM connection is online? Trying to hyperterm to the EZB via my wifi TLG.....virtual com port says it is sending and receiving but no luck with EZB.

staying tuned as this may be the same issue I am having.

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.
