Hi DJ & EZ-Robot community,
I have a problem with the firmware update. I got back the following error message below:
Attempting connection on COM6
Connection Failed: System.IO.IOException: The semaphore timeout period has expired.
at System.IO.Ports.InternalResources.WinIOError(Int32 errorCode, String str)
at System.IO.Ports.SerialStream..ctor(String portName, Int32 baudRate, Parity parity, Int32 dataBits, StopBits stopBits, Int32 readTimeout, Int32 writeTimeout, Handshake handshake, Boolean dtrEnable, Boolean rtsEnable, Boolean discardNull, Byte parityReplace)
at System.IO.Ports.SerialPort.Open()
at EZ_B.EZB.Connect(String hostname, String tcpPassword)
Disconnected
My system is a Windows 7 / 64 bit PC, I'm using latest ARC version 2013.01.05.00. I changed my bluetooth to windows bluetooth stack.
Please help me because this kit is a christmas gift to my stepson.
Thanks from Norway
All we can really tell you is what's been repeated in previous firmware related posts.
If none of that solves the problem, copy the debug message from the firmware upgrader and use the Contact Us page to send it to EZ-Robots.
My test results are the following:
- Battery voltage 9,1 V (6 x 1,5V AA Varta)
- I have tested the EZ-B v3 Bluetooth Robot Controller with Digital Multimeter according to the tutorial video and everything was ok!
- Blinking lights are working good (blue light fast pulsing, red also pulsing fast)
- I have changed my Bluetooth stack from Broadcom to Microsoft Generic Bluetooth Adapter.
- The com port is the 6
- I have changed the COMPORT many times, but not worked
- I have reinstalled the device, but not worked
I have Microsoft.NET Framework 4.5
What can I do now?
I am using a Samsung RV520 laptop. Inbuilt bluetooth adapter.
Also, I believe DJ updated the firmware upgrader today to fix an issue some were having that hadn't cropped up before, download and install the update and see if that's of any help.
Thank you for your efforts. I was lucky because today I have checked Kalinox posts. He posted in yesterday. DJ Sures solved the problem. Just I realised in Kalinox posts. He is Canadian-French. I am Hungarian, but I live in Norway. We also use comma insted of . in our culture as the french culture. And DJ Sures posted in a print screen how can we change this setting. Holy Ghost... Update sucessfull. Everybody is happy after 3-4 frustrating days.
Thank you again in my stepson name. He can turn his energy to build up a robot. :-)
The latest release will warn if the decimal digit is not correct.
