Version 6 compatibility

[dragonxtek]

Why version 6 is not compatible? I try to connect to it with gattool, but it doesn't connect:

sudo gatttool -t random -b EA:9C:0F:A6:A0:22 -I
[EA:9C:0F:A6:A0:22][LE]> connect
Attempting to connect to EA:9C:0F:A6:A0:22

Does it have an incompatibility with gattool library or something else?

I never tried with a v6. Did you order it recently ?

Try connecting with a public address type :

sudo gatttool -t public -b EA:9C:0F:A6:A0:22 -I

I tried with -t public with V8 and it doesn't works. (only works with -t random). With v6, I can't connect with both of them. I bought it through aliexpress 6 months ago. For v8 I use handle 0x000c and for v6 handle 0x0043, but as I said you, I can't connect throught gattool to test it without the official Android application.

I tested bulb v6 with your app and it works, but only on interactive mode:

sudo python3 magicblueshell.py                                          
Magic Blue interactive shell v0.4.2

> connect 1

> set_color green

When I tried to change the color without interactive mode, it doesn't work:

sudo python3 magicblueshell.py -c 'set_color blue' -m d0:39:72:c8:16:d6

bluepy.btle.BTLEException: Failed to connect to peripheral d0:39:72:c8:16:d6, addr type: random

Do you know why it doesn't works? What is the difference between interactive connection and non-interactive connection?

I tried with MAC but it doesn't work, but if I use the ID it works. Why is it?

I solved! I don't know why, but version 6, is equal to version 9 or 10.

read device_info
INFO:__main__:Received device_info: {'r': 0, 'effect_speed': 0, 'brightness': 255, 'device_type': 21, 'version': 6, 'on': True, 'g': 0, 'effect': None, 'effect_no': 65, 'b': 0}

If I choose any of these versions, it works sudo python3 magicblueshell.py -c 'set_warm_light 1.0' -m d0:39:72:c8:16:d6 -b 9

Do you know why it doesn't works? What is the difference between interactive connection and non-interactive connection?

Interactive mode auto-detect address type during scan. We don't do this when connecting directly or using the library for performance reasons.

However setting version to 9 or 10 forces address type to be a public address, that means v6 uses a public address type too. I'll make a commit to officially support this version with the info you provided.

Thanks for your feedback 👍

Merged with master, will be included in next release. You can continue to use -b 9 or -b 10, it won't have any other impacts.
