Can someone help me or point me to a tutorial on how to use two EZB v3s together? Can't seem to come up with much searching the forum.

Thanks

I have found a few conversations, tutorials and activities that may help with your question. Take a look at these links. I've sorted them by what I believe to be most relevant but that is not always the case as I'm still learning.


Also, consider reviewing the Learn section for informative lessons and activities. Check it out!

Short of an actual cable (since ezb3 can't receive serial, so not sure how useful this would be) it would have to be done through ez builder... The bluetooth on both ezb3's is already in use to connect to your pc... It could work like this... One ezb3 sends info back to ez builder then ez builder conveys that info to the 2nd ezb3...

Hi Gwen,

In EZ-Builder, you have seen how to connect to 1 single v3, correct? And you have seen in the connection settings there are 5 (0-4) available connections? Well to connect to another ezbv3 you simply repeat the steps and select another connection - meaning if 0 was used for your 1st ezbv3, then use connection 1 for the 2nd ezbv3.

Then as you'll see in the configuration menu of any control you add, there is an option to select which board (0-4) it is connecting to.

You may need a second usb Bluetooth dongle to support another virtual serial connection though.

Guess I didnt even consider ez builder could connect via bluetooth to more that one bluetooth device at a time since i didnt know that was even possible with windows...

Second bluetooth dongle, duh... Gotta get out of the box in my head.

Thanks guys!

That is too simple if it works. Winky

It's not called EZ-Robot because DJ liked the letter Z and E Winky

You shouldn't need a second bluetooth dongle unless you find that the comms is bottlenecking due to scripts running too fast. It's not been an issue with only 2 EZ-B V3s before that I have seen though nor have I experienced it when running 2 from one EZ-Builder, 1 PC and 1 BT dongle.

One thing to bear in mind, one EZ-Builder means only one Movement Panel (which controls ports on board 0 only).

Gotta love EZ Smile

Thanks!

One additional note (I always seem to have just ine more). If you really really need two Movement Panels, and don't need much or any coordinaruin between what the two EZ-Bs are doing, you can run two instances of EZ-Builder on the same PC, each controlling one board.

The main limitation woukd be if you have speech recognition in both projects, only one is likely to work at a time.
