Does A21 Bulb support Alljoyn Onboarding ?
I have an A21 and I checked the onboarding is not supported yet.
Then when it will be available. I dont wanna buy White one just to test onboarding, please guys make it 
You are correct, the A21 bulb does not currently support Alljoyn. I do not have an ETA for when it will.
Does it supports now ?
Nope. There has been no movement on this so far.
