how to work Ganglion board by Arduino IDE?

I have tried to use CYTON board plus WIFISHIELD board, communicate with CYTON board through ARDUINO IDE and use the CYTON board SDK you gave, change the sample rate to 4000HZ, and format the SD card, then use the WIFI SHIELD board SDK for STREAM/START, to start the CYTON board and the WIFISHIELD board to collect data and record it on the SD card. This method does allow me to get the data of the 4000HZ sample rate, but the data itself has many burrs, and the data is not very accurate. So I want to use the same method for GANGLION board with WIFI SHIELD board to collect data at the sample rate 6400 HZ, but I can't connect ARDUINO IDE to GANGLION board anyway and use the SDK to change the sample rate. In fact, they are not connected at all, ARDUIO can not find the virtual serial port to communicate with it, how can I record data with SD card by changing the sample rate of GANGLION board, I have another question, if GANGLION board Can't communicate with ARDUINO IDE, so what is your GANGLION SDK for, and is there any other IDE that can communicate?

    I have another question. When I used CYTON and WIFI SHIELD to collect data, I did not follow your tutorial that the power supply of CYTON uses four AA 1.5V batteries, but rechargeable batteries four 1.2V, so there is a total of 1.2V less, and the battery of the WIFI SHIELD board, I did not use a 3.7V lithium battery, but also used four 1.2V rechargeable batteries, a total of 4.8V, so that is more 1.1V, I found that there are many glitches in the data I collected, and your CYTON manual says that the working voltage of CYTON is 3.0V-6V, and the working voltage of WFIFI SHIELD is 3.3V. I ask, the data is not good and inaccurate , Is it related to battery mismatch? The main power supply voltage of the CYTON board is 1.2V less, while the power supply voltage of the WIFI SHIELD board is 1.1V more. Does it affect the work of the two boards?

    Hi Profeell,

    The Wifi Shield is being redesigned to repair any lost packets that were happening with Cyton. However because of internal engineering priorities (Galea product), the Shield has a lower priority.

    However it did always work best and correctly with the Ganglion. Additionally the SD card slot on the Ganglion was never supported, because of timing issues with the Simblee processor. This is clarified on some of the Forum and Shop pages. Ganglion does NOT appear as a usb serial COM port. Instead it is a Bluetooth device, which is accessed ONLY through the BLED112 dongle. This dongle does the conversion between Bluetooth and serial 'command' formats.

    re: Cyton and Wifi Shield power supplies. Specific recommendations are given in some of the Forum posts regarding best configurations for operation. As I recall one suggestion was to power the Shield and Cyton with separate AA 1.5V packs, to maximize the power supply voltages. It was also suggested to use the UDPx3 mode, because power supply spikes caused by the TCP mode, were impacting packet loss.
