Hello from Russia. I'm trying to connect with my ez-robot.
Step 5 from the video tutorial is going fine. But when I'm trying to connect to my ez-robot (the lowest port is COM8) form the ARC I'm getting error:
EZB 0:
EZB 1:
EZB 2:
EZB 3:
EZB 4:
TCP Server stopped

Attempting connection on COM8
Comm Err: ????? ???????? ???????? ???????. !(it says about time out)
BbytesToExpect: 1
Received:

Connection Failed: System.Exception: Controller Not Responding
? EZ_B.EZB.Connect(String hostname, String tcpPassword, Int32 baudRate)
Disconnected
Does anybody know what is going on?
Thanks in advance.
If it did pair ok try the firmware updater as in step 6 1st
I took a bunch of screen shots when I updated one of my EZ-Bs which hopefully will aid you in connection. Take a look at this topic
To @winstn60: I don't start ARC at step 5. I'm starting it at step 11.
I did pair laptop with EZ-Robot and I did update the firmware. Still getting the same error. And even more. Now I can't connect to the EZ-Robot from Firmware Updater, getting the same error as from ARC.
I've tried to delete Bluetooth and pair it again. tried to pair it with another laptop, pairing is ok, but then the same error.
Also make sure you have fresh batteries or a power supply plugged in to power the EZ-B
If it pairs ok but wont connect its some sort of controller issue also check every pin is correctly soldered to the main board
There are tutorials on this site to check the voltages etc at various points on the main board
Here
Hope this helps?
So if you already have com8 and you added com9 and com10, the ez-b would be com9.
Original poster is connecting to the wrong com port.
What com ports are listed on your system? Type us the list that appears in the drop down for ARC ports.
I'm selecting the lowest port from available in the ARC.
I tried to delete and add EZ-Robot in the bluetooth devices several times. Each time when I add EZ-Robot bluetooth device, it starting to use next port numbers. Last time, I've deleted all ports that was used previously and ez-robot bluetooth device. Then I've paired laptop with EZ-robot again, it starts to use COM3 port, still the same error.
Here's some screenshots of the ARC and bluetooth device.

Really can't understand what am I doing wrong. I'm starting to suspect maybe can it be because of language of operating system is Russian?
Please watch the Adding Bluetooth tutorial video. Link is here: http://www.ez-robot.com/Tutorials/Default.aspx?id=5

Step #9 reads:
I do not think I can re-word that any different.
As for your original post, you mentioned that the Firmware was successfully updated. Can you verify that the red light flashes, and the blue light pulses?
I'm sorry, when I say the lowest, I'm talking about the lowest number, not the lowest position on the screen.
Anyway, I've tried to connect to COM3 as well as to COM5

Click Start --> Devices and Printers
Right click on the EZ-B --> Properties --> Services
Both of mine only show the one COM port which is the one to connect to. If it shows 2 it's the lower of the 2 (i.e. if it shows COM10 and COM11 choose COM10)
Check if you are using the Microsoft standard bluetooth drivers You have an odd looking bluetooth device in your system tray. I would delete all Bluetooth devices and Drivers and start again with just the EZ-B. It looks like you have a bluetooth dongle device plugged in does your laptop not have BT built in? unusual nowadays it maybe a conflict
Its unlikely to be a language issue as others have been succesful in Russia
I'd like ask you, maybe any of you could connect to my laptop remotely and try to help.
It was supposed to be a present for my son, who actually has found ez-robot web-site. He really wants ez-robot work.
