Channels 7 and 8 have a problem that data from the board doesn't change
When I started recording normally with Cyton and the Bluetooth dongle, channels 7 and 8 had the problem that data from the board didn't change, but other channels had no problem. There was the same problem on Cyton+Daisy.

Would anyone have any insight into this? I wonder whether the problem is related to hardware.
Thank you!

The ADS1299 chip has a '-6' suffix.
Right, you are using a fake 'clone' board not manufactured by OpenBCI. Sorry.
