BB9E - play_animation gives TimeoutError

[mjuchno]

I played around with basic movement and LEDs and all work great.

However, I wanted to test build-in animations and play_animation() gives me TimeoutError().
I don't see play_animation() in the documentation so I'm not sure if this is really implemented and if it works how I understand it.

Any help would be greatly appreciated.

Was the animation being played? If no, then I think BB-9E does not support that animation (or any animation at all).

When I code this, I remember that animations on some droids are actually just a bunch of coordinated movements. Only R2-D2 and -Q5 are for sure equipped with a dedicated animation command, but I forgot whether BB-9E supports that dedicated animation command or just the former case.

When I have time I will look into the code again.

Thanks!

The animation was not played but it also did not return "Animation cannot be play by this toy" like it did when I was using IntEnum the wrong way.

The list of Animations(IntEnum) in toy/bb9e.py resembles expressions that are available in the official Droid app so I though that the sequence sits in the firmware and it is trigger by an app.

If this is not the case I will try to reproduce these with raw_motor() sequence but it doesn't seem so responsive as expressions in the Droid app.

This is frustrating when it comes to the BB8 model. It doesnt seem to run off the same code as the BB9E and enums for animation dont seem to be relevant although on the app they work just fine.

[superfashi]

I remember BB8's animation is just a bunch of movements hard-coded on the app side. Check the js file, inside it should have a mapping of an animation to a list of movements.

[Cole1220]

Given BB8 and BB9E are so different, I wont be able to further test BB9E until I can get my hands on one. Updates have been made to the class if that helps. BB8 changes are in pull request

I found this (I think) and this is going to be a while... but it WILL happen

Hi,

I have the same issue with R2-D2...

@opasco What is the problem?

[opasco]

when I call play_animation() nothing happens and I get a timeout error.

[superfashi]

when I call play_animation() nothing happens and I get a timeout error.

does any other command works? Can you try with sphero EDU app and see if it works?

[opasco]

yes, the sounds and lights commands I tried work and the animation commands work fine with Sphero EDU.

[superfashi]

Ok, can you send the stack tract of the timeout error here?

[opasco]

Sure:

[superfashi]

thanks. can you post your entire code and uncomment this line?

spherov2.py/spherov2/toy/__init__.py

Line 76 in 2f11b4e

# print('request ' + ' '.join([hex(c) for c in payload]))

and then post the entire output as well.

[opasco]

Here is my code:

import time

from spherov2 import scanner
from spherov2.sphero_edu import SpheroEduAPI
from spherov2.sphero_edu import Stance
from spherov2.types import Color
from spherov2.toy.r2d2 import R2D2

sleep_timer = 5
r2_stance = Stance.Bipod

print("Connecting to Droid...")
toy = scanner.find_toy()
if toy is not None:
    print("Connected to " + toy.toy_type.display_name)
    with SpheroEduAPI(toy) as droid:
        droid.play_animation(R2D2.Animations.WWM_YOOHOO)

        print("Disconnected from " + toy.toy_type.display_name)

And here is the output after uncommenting the line:

Ok I don't see anything particularly wrong... I don't have an R2D2 with me so I can't test. One thing you can try is to use b124fe0 this version. (pip install spherov2=0.8.2) which I know is working.

[opasco]

I actually get the same error after installing version 0.8.2

[superfashi]

Okay, then I suspect it's model issue, because I knew 0.8.2 was working. You said it works with the Edu App, which is very peculiar. I don't know if you can debug it by yourself, but it looks like your R2-D2 just straight up not accepting the command.

[opasco]

Any guidance on how I could debug it?

[superfashi]

one thing you could try doing is to have a BLE packet debugger/interceptor on a Android device, and compare it to the packets sent by python.
