OpenBCI GUI connection error
I'm using the Cyton in debug mode (serial output via SERIAL1, D11/D12 pins). After this, when I attempt to plug in the USB dongle and connect via OPENBCI GUI, connections fails. It is important to note that the dongle actually connects successfully via channel 20, but when I click auto-scan, it just skips past channel 20 and fails the autoscan! I try everything here https://docs.openbci.com/Troubleshooting/GUI_Troubleshooting/ but the problem persists. It seems that the UART window on my laptop to communicate serially with the dongle indicates the connection is perfect, but the GUI just won't open a session.

You'll have to check the firmware code, this feature is only intended for the firmware developers, not end users. I believe that once you have switched the Cyton mainboard to use the 'debug mode', it may then abandon sending on the normal pathway. Power cycling the mainboard will return to normal mode.
The two RFDuino's independently establish connectivity via their radio links. So from the dongle viewpoint the radio channel is fine.
