Nope... wifi only... Why you you want to use Bluetooth when wifi is so infinitely better? Faster, longer range and with a more stable connection to boot....

Because I'm trying to control two different robots, the other one can be connected via bluetooth. So I was thinking if I could connect EZ-B controller so that I can transmit data between.

If it's connected via wifi, is that doable?

Are you trying to connect to the robot's existing connection and expecting to be able to use the EZ-B to send commands to it? If so that isn't how the EZ-B works.

The ezb4 is a slave device... Meaning it can only communicate with your PC. It can't communicate between another ezb...

You can connect up to 5 ezb4s to ARC at a time... As I said however, the ezbs can only communicate with your PC and not each other...

OK, I see, thanks very much.
