I can see appropriate date being written to the SD card when I manually command the Cyton to stream to the SD card using the serial cable with putty.

For debugging, I hardwired to the serial port on the Cyton with a FTDI chip USB serial cable/putty. All of the Cyton hardware is working. I can issue commands, configure hardware, stream to the SD car

2) 'Write to SD Card' is set to '12 hour maximum'

I believe the CytonDaisy sample rate is 125 Hz, regardless if you are saving the data to GUI folder or to microSD card.

I did a few of experiences and I found that the same issue cause using another SD or CytonDaisy board but Gelfree did not cause the issue.

Thank you for your help. I see. I will try to use my cheaper SD card, it's normal quality.

I'm stumped regarding why your 250 Hz SD card recordings are lower amplitude than GUI streamed recordings.

So please confirm. You are saying that there are NO amplitude differences (streaming vs SD card), when using the default sampling rate of 250 Hz. The weaker amplitude SD card signals only show up when

re: higher sample rates with SD card

I suggest you email (contact at openbci.com), which is customer service. As you can see from the previous links, support for higher sample rates to the sd card WAS implemented, but for a previous firm

In the docs you link above for the SDK, it says

I've seen that the max sampling rate is 250 Hz over Bluetooth, but over WiFi, it can go as high as 16kHz. Is it possible, then, for us to disable Bluetooth, and instead save our data to an SD card sam

I'm uncertain if there is support for higher sd card sample rates, in the default Cyton firmware. This was implemented as a custom user-created option in the DISTANT past, with an earlier firmware ver

I think we bought it a year ago. We are using the recommended SD card on https://docs.openbci.com/Cyton/CytonSDCard/. We haven't tried changing the SD card because it just happened once after using US

We turn off the board when data collection is over and then we take the sd card out from the board. just wondering if we are removing sd card properly? or do we have any a proper SD card removal metho

We are having some issues with SD card files being empty after the data collection. This had happened to us before when we didn't use USB extension cable for dongle. However, after using USB extension
