Unable to resolve a network EEG stream from EGI Amp Server #28

Open GoogleCodeExporter opened 9 years ago

Dear all,

I'm unable to resolve a network stream from an EGI Net Amps 300 neither with 
the ReceiveData Python nor MATLAB example scripts.

First I have tried to connect to the Net Amps 300 via a provided GUI "EGI Amp 
Server Connector". This program crashes a second after pressing the "Link" 
button. The resulting error message is "EGIAmpServer.exe has stopped working". 
I use default settings with the IP address of the Mac host.

Second I have attempted to use the OpenVibe Acquisition Server GUI to establish 
a connection to the Amplifier. As described in your Wiki page I change the 
AmpServer host name to its IP address, press "Connect" and "Play". I see the 
device drift bar moving. After that I try to launch Python or MATLAB scripts to 
resolve the network stream. Neither the standard "resolve_stream("type", 
"EGI")" nor the generic "resolve_streams(5)" work. 'streams' structure is empty 
and I'm unable to create an inlet.

On the other hand using the OpenVibe's pair of AcquisitionClient--Signal 
Display I can receive and display the data.

I would appreciate any guidance in resolving the EEG network stream. Is it 
possible you tell me the basic steps performed by EGIAmpServer program that I 
could try to reproduce them manually? Thank you. 

Software used:

Host
-----
Mac OS X 10.6.8
Net Station 4.5.4
EGI Net Amps 300

Client
-------
Windows 7, x64
python 2.7.9 x64
