Playbulb Garden #4

Open effem opened 9 years ago

effem commented 9 years ago

Hi,

I tried to test some command listed here with my Playbulb garden but it seems that they changed the command structure?

$ sudo hcitool lescan
LE Scan ...
D2:57:4B:FF:FF:FF (unknown)
D2:57:4B:FF:FF:FF PLAYBULB GARDEN
^C
$ gatttool -b D2:57:4B:FF:FF:FF --char-write -a 0x0016 -n 0000ff00
$

But the PlayBulb Garden stays white...

Is there any way to sniff the communication between the app and the device to see what data is actually send?

You can use char-read-hnd for example to read out a specific characteristic. Then change settings on the device, and see what has changed. It is possible that the color value is in another characteristic.

I looked online to find examples on how to use the char-read-hnd and found some that used the "interactive"?! interface of gatttool but im not able to connect:

$ gatttool -b D2:57:4B:FF:FF:FF -I
[   ][D2:57:4B:FF:FF:FF][LE]> connect
Connecting... connect error: Connection refused (111)
[   ][D2:57:4B:FF:FF:FF][LE]>

Then I tried to read directly via command:

$ gatttool -b D2:57:4B:FF:FF:FF --char-read -a 0x0016
Connection refused (111)

Any ideas on how to proceed?

Hi, I used the bluetooth snooping capabilities of my android phone to sniff the playbulb garden protocol:

gatttool -b 12:34:56:78:90:XX --char-write -a 0x001b -n 0000ff00 sets the color to green!

It seems that this https://github.com/Phhere/Playbulb/blob/master/protocols/color.md represents the protocol but the code is offset by 3:

0x0016 -> 0x0019 0x0018 -> 0x001b

etc.

derchrisuk commented 9 years ago

It is possible that each product has their own protocol codes. I have no Playbulb Garden so not able to confirm this.

Hi,

Just for gathering other models : Blue Label (the cheap color only) and new Sphere are using the same like Garden

kevinmost commented 8 years ago

For the record, I'm trying to use these new handles with the Sphere and it doesn't seem to be working. See my comment: https://github.com/Phhere/Playbulb/issues/12#issuecomment-238120045
