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 TCP Server stopped TCP Server stopped TCP Server stopped TCP Server stopped Attempting connection on COM8 Comm Err: ????? ???????? ???????? ???????. !(it says about time out) BbytesToExpect: 1
Received: Disconnected 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.
You shouldnt be starting ARC at Step 5 just pairing the Bluetooth with your PC/Laptop
If it did pair ok try the firmware updater as in step 6 1st
As @winstn60 said, make sure it's paired and updated.
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
Thank you all for replies. 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.
Do the lights flash on the bluetooth board and the main board when you power up?
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?
I think the original poster is having confusion with the part about lowest com port. The statement was never "lowest com port" on any tutorial. The statement is "lowest of the two com ports that were detected".
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.
With each Bluetooth device windows remembers you can right click and choose properties , second tab I believe shows the assigned com port. I recommend naming the the blutooth devices so you can tell which ezb is the one your trying to connect if you have more than one. - Josh S
Thank you guys for replies. 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. http://s019.radikal.ru/i626/1304/e5/99ca10e55b32.jpg http://i069.radikal.ru/1304/d0/1c5509422713.jpg
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?
Again, do not select the lowest COM port available in ARC. That's not what the tutorials say.
Please watch the Adding Bluetooth tutorial video. Link is here: https://synthiam.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?
