Hi

Thanks for reporting

We are aware of the compatibility issue between PyGaze and version 0.9.77. I have created a bug report and will report back once it has been resolved by our developers.

For now, please use version 0.9.56 until we get a patch out.

Update:

We've now debugged the PyTribe.py implementation. The reason it fails with the new server is due to stricter JSON validation.

Message sent to server from PyGaze:

Code:: { "category": "calibration", "request": "pointend", }

Upon validating with JSONLint following error is reported.

Code:: Error: Parse error on line 3: ...quest": "pointend",} ----------------------^ Expecting 'STRING', got '}'

The last comma after pointend is not allowed in JSON whereby the server rejects the message.
It's a matter of a single character.

Error when trying to calibrate with Opensesame PyGaze

2016-05-20T02:22:08+02:00

Hi, i'm trying to set an experiment in Opensesame with the ET, but the calibration phase always ends crashing. I have the ET server on and this happens even in the template pre-packaged to be used with the eye tracker.

The log of the EyeTribe brings something like this (i suppose this is the important part):

Code:: 2016-05-13 17:42:29.815|2340015440|I|Validating config chosen device 2016-05-13 17:42:42.817|2427200557|I|New connection detected [176093691904] 2016-05-13 17:42:43.853|1886814084|I|Setting up device properties 2016-05-13 17:42:43.899|1886814084|I|The device stream has started 2016-05-13 17:42:43.910|2427200557|I|Tracker started 2016-05-13 17:42:43.910|2427200557|I|Creating new connection [176093691904] 2016-05-13 17:42:47.213|2427200557|E|Invalid JSON format: [{ "category": "calibration", "request": "pointend", }] 2016-05-13 17:42:48.337|2427200557|I|Connection removed [176093691904] 2016-05-13 17:42:49.133|1886814084|I|The device stream has stopped 2016-05-13 17:42:49.137|2427200557|I|Tracker stopped

Any help is greatly appreciated!
