kvantetore / igrill Goto Github PK

Hi !
I've got an iGrill Mini and I have tried with all keys found in the latest apk but I always end up with "Invalid device challenge" (I've set correct MAC address too of course) :

Authenticating...
encrypted device challenge: 954410c3d04a945fb4e986b4e18bb7cb
decrypted device challenge: 1a8659a80d5d5a89ca3fc549efad0544
Invalid device challenge
Traceback (most recent call last):
File "monitor_igrill_v2.py", line 18, in
periph = IGrillV2Peripheral(ADDRESS)
File "/home/pi/igrill-master/igrill.py", line 130, in init
IDevicePeripheral.init(self, address)
File "/home/pi/igrill-master/igrill.py", line 46, in init
raise RuntimeError("Unable to authenticate with device")
RuntimeError: Unable to authenticate with device

Is there sopmething obvious that I am unable to see missing here for me to be able to connect ?

Cheers & TIA !

Has any of the newer releases been tested?

Maybe someone can give me a hand here. I've got an igrill2 I'm trying to use with this library using an raspberry pi. Following the instructions above, I did decompile the idevices's app apk file I found in the web and did find the .plist files under the assets/device/igrill_bundle directory. Although I can sorta follow along were you found the UUID's for firmware, etc. I still can't figure out how you determined the encryption key. Please point me in the right direction.

Note: using the Pi, I am able to see the igrill to and obtain its MAC address. I did plug that into the library.

Hey nice work. Not too familiar with Python, what protocols are you using to talk to the Igrill? I'd like to re implement some of your work in my lanauge of choice.

Where did you get the encryption key here:

Is that something that comes out of bonding with bluetoothctl or something you managed to find elsewhere? I've got an iGrill2 I'm trying to toy around with but reading your code the step of finding that key is non-obvious.

Followed instructions and all I get is

Hi

I'm attempting to get igrill setup to monitor my iGrill Mini.
I've setup a virtualenv with all the required libraries, I've also edited main.py with my device's address, but I get this error when running:

# python main.py

Any idea what I'm doing wrong?

Hi,

I've been very noisy on this project-issue page in the last few hours...

So far I'm now able to connect my Raspberry Pi to my iGrill V2 (with some startup-problems).

My last problem is now that it seems, that the values are read wrong (I'm always getting a temperature of 202 or 190 something) - which is even in imperal-system crap... ;-)

Can you provide me some hints, how you identified the data-fields for your iGrill mini?

Thanks
