Cyton signals only for 15-20 minutes?

Hello @wjcroft @retiutut and @evaesteban
My daughter and I are using the electrode cap with the Cyton board for her high school project. We noticed that the signals are seen on the GUI only for 15 - 20 minutes of a session, then no signals are detected on the GUI. Are we doing something wrong? or is there a configuration we are missing? We want to experiment for few hours at a stretch monitoring waves when a subject is being entertained.
Please advise.

Keyur, hi.
I assume this is a recent purchase and you are running the latest GUI, latest Cyton firmware, up to date FTDI usb serial driver, etc. Please try running your experiment on another computer, to eliminate any OS, hardware, usb port issues.

Hello William @wjcroft,
Yes it is a recent purchase. I have tried it on two different macbooks. I assume the firmware on the Cyton is latest as I received it only a few days back. I have not updated the firmware on it.
So you confirm it freezes on both MacBooks? You might have a defective dongle or mainboard. Could you possible try it on a Windows machine, just to eliminate a possible issue with the macOS or mac hardware? You have the latest firmware.
I will run it on Windows and let you know.
@wjcroft Yes it freezes on both Macbooks.
It sounds likely that it will freeze again on Windows, but worth a try.
When it freezes, is there any action you can do on the GUI to restart the data stream? Or is it required to power cycle? Do you need to power cycle both mainboard and dongle? Or is the mainboard alone enough?
Assuming it fails the same on Windows, send an email to contact @ openbci.com and explain your defective hardware. They should be able to send a replacement.

Actually there are two possibilities: bad dongle or bad motherboard. You can try unplugging / plugging the dongle first. Then see if GUI can talk with Cyton. Then power cycle mainboard. If dongle power cycle fixed it, possibly a replacement dongle may fix. But customer support would likely want to replace both at same time.
There is a very remote possibility the firmware is suspect on dongle or mainboard, but I don't think so. Because the time to failure varies.
@wjcroft Unfortunately on windows the GUI did not recognize any data stream to start with. The same thing happened on the mac also. No signal was detected after yesterday for a brief period of time even after powering the board off or by removing the dongle.
