unable to get the dongle to properly communicate to Cyton

edited August 2017 in Cyton

I updated the USB (OpenBCI) dongle FTDI
drivers to Windows 2.12.26

Made certain the blue light is lit and
the dongle switch in in the GPIO 6 position (towards the computer).

Cyton board is switched on in the PC
position and the blue LED is lit.

I launch the OpenBCI software and
select the “LIVE (from Cyton)” option, serial/com connection
“COM4” is selected (my only option).

On the Radio Configuration section the
status continue to show “Failure: system is down”.

I have tried the changing the channel,
override dongle, autoscan procedures and get the same result as noted
above. I have shut everything down and brought things up in order
(e.g. 1- USB Dongle, 2- Cyton board, 3- OpenBCI software) and see the
same result.

I have read through the Forum
suggestions and do not see anything suggested (or in any different
order) then I have already tried. Does anyone have any other
suggestions or see anything I may have missed?

    Hi! Please close the OpenBCI_GUI.

    Remove the Dongle and plug it back in. 

    Power OFF/ON the Cyton. Verify there is no red light on the Dongle when you turn the board on, indicates your radios are not talking together.

    Launch the OpenBCI GUI, then click Live From Cyton, click your COM4, and press the ">" button at the top right of the panel to bring up the radio config panel. 

    Press Autoscan. Your radios will be aligned now. You may press "Status" and see the system is up!

    Thanks

    Hi, thanks for the suggestion. No red lights but I get the same result, as previously reported, in the OpenBCI Gui- this did not work.
  • pushtheworldpushtheworld
    No red lights? Sounds like you have version 1.0.0 radio firmware.

    When did you buy it? Is it 32bit?
  • pushtheworldpushtheworld
    Are you seeing red and green lights when you press auto scan?
  • slackconsultingslackconsulting
    Purchased this a week ago, when the dongle is plugged in and I'm not doing anything there is a blue light on the dongle and a blue light on the Cyton board, when I auto scan the only difference in lights I see is a large flicker between the transmit and receive light's (then once the communication stops so do the flickering lights).
  • pushtheworldpushtheworld
    And out of the box the device never worked? That's so frustrating. I would recommend emailing contact @ openbci . com (without the spaces) to bring this issue up to them. I'm really amazed that you can't align the radio channels. The boards are tested before they leave so I'm concerned your RFduino device radio has been damaged.
  • slackconsultingslackconsulting
    Yes never worked out of the box. I sent an inquiry to sales @ openbci . com yesterday and I will take your advise and forward that same inquiry to contact @ openbci . com.

    Thank you for assist and advice.

    @slackconsulting not sure your hardware level of expertise but you can try re programming the radios. If you don't have experience with Arduino and serial communications the reflashing can be cumbersome

    I have a similar problem, although I'm afraid this is one of many.  The FTDI drivers said that if Windows found the drivers automatically, I wouldn't have to install the CDM v2.12.  This is exactly what happened, so I tried it, but the waves were sporadic and while working didn't seem to have anything to do with my brain (there were no eye blink artifacts or jaw artifacts, some steady waves, but random surges and dead spots)  The next time day, I couldn't get the radio signal to connect.  The serial port/COM wasn't showing up.  I checked the port under "devices", and it said there were no drivers, so I reinstalled the CDM drivers, and Windows said that the proper drivers were already installed.  Back to the GUI and the same problem.  I kept going in circles because it apparently was slipping off the drivers somehow.  Now it is connecting to the USB port, but the signals are flatlined, and nothing under the FFT plot.
  • pushtheworldpushtheworld
    @brainham can you tell us more about what hardware you're using?

    Cyton 32bit?
    Firmware?
    Windows 10?
    Latency of Virtual Serial Port?

    Ugh serial port... How I dispise it! Sorry for all these frustrating problems! I feel your pain, it's why I made the wifi shield...
  • brainhambrainham
    Cyton with Daisy creating 16 channels, although I tried disconnecting the Daisy in case the extra channels were causing the instability- no difference.  I'm back to 16 channels.  Windows 7.  Not sure what latency of the virtual serial port is.
  • pushtheworldpushtheworld
    Can you please try from Windows 10?
  • wjcroftwjcroft Mount Shasta, CA
    @brainham, this describes the Latency adjustment. Absolutely necessary for proper operation.


  • brainhambrainham
    OK, I'll try these.  Thanks guys!

  • brainhambrainham
    Adjusting the latency was easy, but the problem with Windows 7 was that it was timing out trying to install the drivers.  (Although sometimes it would say the device was working properly, sometimes "drivers already installed", sometimes "no drivers," but then time out during installation.)   I tried on a Windows 10 Lenovo and the port stability was good!  It always showed up in the serial port list.  However, still software issues- difficulty starting system, cycling back to start screen, and flat-lining.  I had some glimmers of success, but I've run out of time. 
  • pushtheworldpushtheworld
    @brainham we have a new GUI coming out soon that will completely change the way Cyton serial is done, for the better!
  • brainhambrainham
    Great!

    I consistently have the equipment
    working now and wanted to share the results/findings in the event it
    helps someone else out.



    Turned out I was getting interference
    from my wireless mouse- when I turned the mouse itself off (has a
    switch) I was able to move the dongle to any usb port I wanted (usb 2
    or 3), establish communication with the Com port and radio
    communication to the Cyton board. Once I was certain I had an
    operational system I updated the latency setting with adjustment from
    16 to 1, once restarted I noticed seemingly quicker channel graph
    results.

    Thank you to all that contributed to
    this thread- the advice was very helpful, I now consider my issue
    resolved.

    @slackconsulting

    Mind blown. Can you please post the Mouse model number incase someone else has similar issues!
  • slackconsultingslackconsulting
    Indeed, just shutting off the mouse seemed to resolve my issues. 
    Mouse= Amazon Basics Model #: MG-0975 

    I will continue observations, if I run into any other noteworthy comm issues I will find this tread and update.

    Hey, I have a similar issue, my dongle gets connected for the first time though and it shows "system is up" but when I try it again, the usb port doesn't show up. I Try shutting down the laptop as well but same results even after restarting. Its around after 3-4 hours when the whole system is again started, the usb connects but again only once. 
    I'm using cyton 8-channel.
    On, ubuntu 16.04 64 bit.
    Please do tell what problem there could be?
  • pushtheworldpushtheworld
    It's the hub running? What version of the GUI are you running?
  • aarohi1510001aarohi1510001 Ghaziabad, Delhi
    Processing 3.3, none other version worked properly on linux, except this one!
  • pushtheworldpushtheworld
    Is the OpenBCIHub running? Did you run the downloaded OpenBCI_GUI for Linux with sudo?
  • aarohi1510001aarohi1510001 Ghaziabad, Delhi
    edited September 2017
    Yes it did run and used sudo for that.
    Its works fine only once, next time the usb doesn't show in the list.
  • pushtheworldpushtheworld
    Can you please upload screen shots? Not being able to see the USB is a strange issue i have not seen yet.
  • pushtheworldpushtheworld
    Is there an error on the bottom of the GUI?
  • pushtheworldpushtheworld
    Can you try running with v2.2.0 of the OpenBCI GUI? 64-bit v2.2.0
  • aarohi1510001aarohi1510001 Ghaziabad, Delhi
    Okay I will send the screenshots asap..
    What is there's some error in the drivers?
