Question

is there a way to replace bluetooth with usb cable

DJ Sures · Answer

If you use a TTL usb adapter, yup Connect the RX and TX lines off the TTL usb adapter to the EZ-B plug and voila

Excuse my ignorance Will EZ B still connect to ARC for programing i want my bot to be autominous so i don't mind not having BT control over it

Niek · Answer

Yes, My omnibot has a USB->TTL adapter i got from SparkFun and it works just like the Bluetooth.

Niek ----What is the part number or link for the USB->TTL adapter you got from Sparkfun? Do you need to also hook up the USB->TTL adapter GND to the EZ-B GND? Or are you only using the Tx and Rx?

Niek · Answer

You can use DEV-09716. Connecting ground is necessary, you can see how i connected mine in my omnibot video part 2 at (1:35):

Thanks Niek! I appreciate the help. So the Sparkfun board Rx goes to Rx on the EZ-B and the Tx goes to Tx on the EZ-B and GND to GND. Will I need to use 3.3V or 5 V?

rgordon · Answer

Niek,

Did you have any problems, or have to make any modifications to the Sparkfun Board you recommended? I am ready to order it now but I read through the comment section and it seems many people have had issues with it.
