Hello,

I was wondering about the measurement units of output, In the README file it says "Channel 8: -0.00001875 Volts." as an example of output. So I would assume the output would be in Volts. However the output scale for simulator and actual device is obviously different.

For simulator is something as in example: -0.00001875
But actual device gives measurements which look more like: -0.1875

So I was wondering what is the reasoning for this difference and what is the actual measurement unit for the device output?

Sincerely,
Agne

Hello,

there seems to be an issue with impedance test for daisy module because this.options.daisy seems to be undefined.

openBCICyton.js line somewhere

Is that only me who has this issue?

Sincerely,
Agne (@agneg)

The python handoff.py is is a totally great interface between OpenBCI Node_JS for real-time BCI. However, it currently looks like it only supports BLE and not wifi. This is quite limiting under the BLE data bandwidth for 16 channels (128Hz)

Please can you bring in the wifi capabilities.

Thanks so much.

Problem

Running the get streaming example (modified) on windows does not work because the Serial port is being closed too fast.

Expected

To be able to connect to the board on windows and stream data from the cyton!

The only get streaming function uses the auto find port function which only works for mac and linux.

A new example should e made for windows or the auto find function should be removed completely.

Hi,
I get the following error:

Failed at the [email protected] install script.
This is probably not a problem with npm. There is likely additional logging output above.

Trying to fix this issue, I installed [email protected] with the instruction :
$npm i serialport@latest

Any ideas will be appreciated.

Hi, I'm working with my university with the Cyton board, we're trying to build a webapp to get data from the board and do some elaborations.
I'm trying to install the package by npm install @openbci/cyton but I keep running into this error:

How can this be solved?

Similar to #15 where the auto find is being used,
