I've been trying for a while to get sample rates of 3200 Hz or more on the Ganglion with Wifi Shield but I just can't get it to work.
I tried using both the Python (OpenBCI_Python > v1.0.1) and NodeJS (OpenBCI_NodeJS_Wifi > master branch) implementations with no success. That's why I'm thinking it could either be a hardware or firmware issue of either the Ganglion or Wifi Shield. I did not test with a Cyton.
The highest sample rate I can get is around 1900-2000 Hz when I set it to 25600 Hz.
Has anyone succeeded in getting 3200 Hz or more working?
These are all the different configurations I've tried in combination:
Latency: different ranges
TCP, UDP and UDP with burst
WiFi Direct and Station
Sample Rates: works fine from 200 Hz to 1600 Hz but none higher
Accelerometer: on and off
Output: raw and JSON
Channels: all 4 and even with just first enabled only
OS: Windows 10 on 2 different computers
WiFi: tried 3 different WiFi transmitters, 2 different routers (when via WiFi Station) in 2 different locations
The shop listing for the WiFi Shield mentions "With a high speed network switch, sample rates over 2000Hz are possible", could this be what I need? What is meant by a "high speed network switch"?

Thanks in advance.
