Epoc+ How to identify if decryption is working?

[minifiredragon]

I have a new EPOC+ with a manufactured date of Jan 03, 2016. With some tweaking I managed to get the headset to start working in the current branch of Emokit. However, the values coming out of the kit do not seem right. I have no electrodes attached to the headset, however the readings are extremely varied and I am not quite sure what I am looking at. But in the pure.eeg software package, they are mostly flat lined.

+========================================================+ | Sensor | Value | Quality | Quality L1 | Quality L2 | +--------+----------+----------+------------+------------+ | F3 | 2068 | 753 | Okay | Nothing | | FC5 | -5321 | 11677 | None | Excellent | | AF3 | -6884 | 16269 | None | Excellent | | F7 | -7062 | 7162 | None | Excellent | | T7 | -2848 | 9569 | None | Excellent | | P7 | -3045 | 9731 | None | Excellent | | O1 | 4394 | 4742 | None | None | | O2 | 519 | 8387 | None | None | | P8 | 2643 | 12962 | None | Excellent | | T8 | 3402 | 2828 | None | None | | F8 | 3949 | 108 | Nothing | Nothing | | AF4 | 139 | 2870 | None | None | | FC6 | -527 | 14005 | None | Excellent | | F4 | -3407 | 14177 | None | Excellent | | X | 63 | N/A | N/A | N/A | | Y | -10 | N/A | N/A | N/A | | Z | ? | N/A | N/A | N/A | | Batt | 227 | N/A | N/A | N/A | +--------+----------+----------+------------+------------+ |Packets Received: 4775 | Packets Processed: 4774 | | Sampling Rate: 192 | Crypto Rate: 192 | +========================================================+

I also had to hard code the battery value to 0 as it kept tossing up values that were not found in the battery.py.

And put a catch in the render.py for "None" as occasionaly the color value would come back None.

I have looked at emofox and emokit fork and need to check the numbers with the EEG software. emofox being the more interesting since the emokit fork does not have any writing out. I have a 1 month subscription to the Premium SDK and I may be able to extend it to 2 to get this all working.

The headset I have is have set the sampling rate to 256, and as you can see above, I am not quite making it to 256, however, it holds steady around 192.

Another thing to note for those using USB 3.0, I have found (atleast on my Win7 Laptop) that it introduces alot of dropped packets on the pure.eeg software, where the good old 2.0 did not.

And lastly, I have a moderate (a bit Webserver based) programing skillset, and I have been looking at the .edf standard. Once I figure out the formating, I was looking to write a python to output in .edf to be used in other software. If I couldn't write it in python there would be a web applet you could load emotiv csv into and get back an edf at the very least.

One final note, the EPOC+ has 16 sensors from what I can tell. 14 of them are the sensor nodes, 2 are reference. There are 2 more at the base of the ear bone which are rubberized. But I think these are reference nodes as well.

Probably need to set is_research=True

[ghost]

A semi-good test, if the headset is not moving, the x and y values should be 0.

[minifiredragon]

I have the is_research set to true (also tried false). X and Y are all over the place as well.

[minifiredragon]

I did some messing around with the emofox creation of emokit. In the code there was something set as a packet loop counter, and I noticed it was set to 127 (which I assume is 128 sample rate of the epoc) I have my headset (and it came out of the box preset) set to 256 samples. So I changed that number to 255 and the timestamp error the unit was reporting disappeared and the battery indicator went to 0 instead of jumping around (If I read correctly, the battery is not always reported). The senors (atleast from what I can tell) did not steady out (X and Y were still moving), but I think this is a step in the right direction.

I was trying to find a similar function within emokit, but I could not find it, but as I noted before my sampling was at 192 on the emokit test. Perhaps if I could find the loop counter I can adjust I can get the battery error in this build to goto 0 as well?

[ghost]

The counter is the first value in the packet data. Set verbose=False, display_output=False and where we have this in packet.py, ~line 30:

        data = self.raw_data
        self.counter = data[0]

Add:

        data = self.raw_data
        self.counter = data[0]
        print(self.counter)

You should see it looping.

[minifiredragon]

Ok, looking at the output it goes from 0 to 255. I changed the if self.counter > 127 to 255 and the battery error stopped and the battery now reads 0 all the time. I am not sure what this means exactly, I am assuming the sensor outputs have been remapped to different byte addresses or mixed in the the 9 new senor outputs.

[ghost]

The battery level is calculated from the counter value, by changing the if statement you are essentially telling it to never calculate the battery level until the counter is greater than 255, which will not happen.

[ghost]

So, the battery level is calculated in some other way now and probably everything else.

For a quick fix I would see if you can change the sampling rate to 128hz.

If you could though, post the raw data with the 256hz setting.

Set write=True and write_decrypted=True, it should generate the file.

[ghost]

The good news, decryption is working it seems.

[minifiredragon]

I tried all 3 settings of the Epoch+, which is Epoch, Epoch+ 128hz, Epoch+ 256. Each one gave the same battery error.

I will try it with the battery forced to 0 and post all three setting results.

And yes, I realized that (about the battery) after I went back and looked at the code regarding the battery level. :)

Alright, looks like we got a bug, I'll get that fixed so we can proceed.

[ghost]

Bug should be squashed, hopefully.

If you could pull the latest master, I included a export decrypted example file.

Did you want me to do all three tests or is this one sufficient?

What is the error? None of these show the counter looping.

You said earlier that it was looping though?

Thanks, ok so with the latest master you should be able to write encrypted.

[ghost]

Also, if you change the mode on the headset does the hid_info.py output change?

[minifiredragon]

I am running out for a little. when I return I will post the encrypted data as well as check to see if the hid_info changes when I change the headset.

[ghost]

Great, we'll get this thing figured out ;)

Ok, thanks for all the data. I will now attempt to create an encryption key solver.

I have no idea how long it will take, but since we know the data format for the normal Epoc, we have the encrypted data and a working headset/key it should be fairly easy and dare I say... fun. lol

[minifiredragon]

Always fun. I wonder what I did with my gpu powered crypto breaking software I had bought years ago. It let you put in a salt and it would run until it was solved. I will have to see if I can dig that up somewhere.

[minifiredragon]

Keep in mind I also have pure.eeg as I have also bought the subscription which will return headset data in edf (though not a valid edf) and CSV.

[ghost]

Nice, once I/we figure out this encryption we're definitely gonna put that to good use.

[ghost]

Alright, so I started on the solver. It hasn't found it yet, but might eventually.

I'm going to add brute force and multiprocessing later, feel free to hack on it, it is in the latest master.

[ghost]

The counter check piece of it is good, made sure with my headset.
