Ez-B Hardwired To Pc?

While Bluetooth is the standard for connecting a PC to the EZ Board and V4 is on the way (WiFi) is it possible to hardwire (USB, etc) for those builders who have room for an onboard PC. Perhaps there is a way to emulate the Bluetooth connection thru hardwire/software? I know there is a Type2 with a stronger signal but that is only one part of the connection circuit. Any thoughts are greatly appreciated.

Just google USB ttl serial. You will find the very simple communication usb port and shows up just like a bluetooth. COM 3, 5 , 7 ect.

I had a tutorial on this for replacing the Bluetooth with cable to the PC.

What I am interested in now is if the V4 can be done the same way as I will have a Mini ITX MB on the robot.

We know that the v4 will have a UART, but I haven't seen anything that clearly states whether that is only for having the EZ-B control other serial devices or if it will accept commands through it as well.

I can't find the thread, but I think DJ said it is also possible to remove the WiFi module and connect another TTL device but that he doesn't recommend it.

I take it that the WiFi is a much more reliable connection than Bluetooth?

I would expect WiFi to be rock solid, particularly with devices physically near each other. Much less susceptible to interference and better error handling than Bluetooth.

Thanks Alan. That's good to know. I will have two EZ-B V3's and one EZ-B V4. I hope it will be ok to have the two old ones hard wired and the new one WIFI. If I remember....somewhere I think I asked this before and I think Rich said it would be ok to have them like that. I just found that even with the Bluetooth right beside the computer, I still had issues with it dropping the connection. But all was solved when I went to cable connection.
