Not merged with master, please install from develop branch :

pip3 install --upgrade git+https://github.com/Betree/pyMagicBlue.git@develop 

Also I can't guarantee your bulb will work as this could be a symptom for an incompatible bulb (if you have a new version for example)

Ok so first problem is fixed as some devices around you aren't broadcasting their names properly.

The second problem that you have is a bit more complicate to diagnose, have you tried following this : How-to-use-manually-with-Gatttool ? It could really help to see if it works with it.

You can also try using bluetoothctl command to send request manually.

There's still two things we can try :

• Connect with gattool using a public address type instead of random (replace MAC_ADDRESS by your bulb mac address like you did in How-to-use-manually-with-Gatttool) :
  sudo gatttool -t public -b MAC_ADDRESS -I

• (And / Or) Try a different handle to change the color (0x0b instead of the usual 0x0c):
  char-write-req 0x000b 56FFFFFF00f0aa to set white
  char-write-req 0x000b 56FF000000f0aa to set red

Most plausible cause is difference in bulbs protocol. I've never tried v8 (yours) nor ever heard of someone who did but v9 needed a special patch that may be required for v8 as well (see #7).

If that works for you the update could be pretty easy 🤞

Thank you very much for trying all of this 👍

Unfortunately I think your bulb version (v8) is currently incompatible. I created an issue specific to discussions about this version #13 and updated the README to state of this incompatibility.

Now if you need this to work you'll have to dig by yourself, I can help you with the basics but not having this bulb I won't be able to study its protocol.
A start would be to get a sniffer, Wireshark on Linux is doing a great job but you may be able to do it by directly logging bluetooth from your Android. You'll then need to see which handle is called and with which values when you change a color.
Finally you can try again using manually with Gatttool with the new values you've got and if it works then fixing magicblue will be as easy as 1-2-3 😉
