state-request works but control doesn't work

[andy2301]

I followed exactly the steps to set up. The state request returns correct information, but the control doesn't work.

Each time I set the color, I could see that the lamp sets the color to my requested one, however it reverts it back to the original color right away. The same happened to setting temperature and setting brightness. It made the change and immediately reverted back.

I also tried turning on and off, but neither worked. Nothing happens with turning on/off.

The following is the debug output.

I'm running the official Raspian Jessie on my Raspberry Pi 3.

Note that, the following command doesn't seem to work.

pi@raspi3:~ $ setcap cap_net_admin,cap_net_raw+eip bluepy-helper
unable to set CAP_SETFCAP effective capability: Operation not permitted

You need to run setcap as root (e.g. with sudo) for it to work, as said by the error message (Operation not permitted).

From the sound of it, I think your lamp is in a mode where it itself adjusts the settings and will directly override the setting. If so there's not much the library can do (without trying to deactivate such modes).
