Bluetooth: Xiaomi temperature/humidity

Hamtaro · November 16, 2020, 7:24pm

Oh! And what does it do?
I saw that it decrypted the data sent over Bluetooth, but apparently, you can run your own programs on it?

So, this should simplify Bluetooth data retrieval.

guim31 · November 18, 2020, 8:55am

Out of curiosity, can this service be used to retrieve information from this Xiaomi sensor?

AlexTrovato · November 18, 2020, 6:25pm

I can’t confirm that for you, I haven’t studied the matter, but to not forget, you can always create an issue on the GitHub of the small program.

I would tell you to try it, but there are a few manipulations to activate Bluetooth under npm, so I need to complete the documentation and fix a first bug.

In short, this tool (me) will be used to test and validate that a Bluetooth device is properly integrated into Gladys.

This is not a super generic Bluetooth tool that does everything, we are really on a case-by-case basis.

guim31 · November 18, 2020, 6:30pm

Got it, thanks for the details!

AlexTrovato · November 21, 2020, 7:05pm

Ok, I have updated the library related to error logs.
You will need to follow the instructions according to the PC’s OS.
Once the instructions are up to date, you will need to update the tool locally with git pull (for those who have already cloned the tool).

I will try to improve it gradually.

I will try with others.
It detected 3 on the first attempt, then 2 on the second, out of 4 (1 is out of range I think and 1 is on the limit)

Same response on another one.
The third one is random in terms of its presence…
Do Bluetooth repeaters exist?

AlexTrovato · November 21, 2020, 8:14pm

Have you tried several times with the LYWSD03MMC?
You should know that Bluetooth is not an exact science
However, if after 3 or 4 attempts (which you’ve done, as far as I understand) you still get nothing, it means I don’t have the right technique for this device. I will therefore look at other sites to find the right way to connect to the LYWSD03MMC.

It seems like the protocol isn’t very stable.
I have a lot of variations in the scans. Do you think flashing them could improve it?

AlexTrovato · November 21, 2020, 8:26pm

Nothing is flashing.

It sometimes happens that devices are not visible, because the scan is done in 5 seconds, which may be a bit short if you scan in a loop.

It’s mainly the NPM library that is not ultra stable.
That’s exactly why I insist on using the same one as Gladys, so as not to have any surprises.

But we’ll get there, keep up the good work

AlexTrovato · November 21, 2020, 9:16pm

@Hamtaro I just delivered a version to scan the device in a more generic way.
It will scan all the visible ports of the device
However, in addition to git pull, you will need to run npm install again

Hamtaro · November 22, 2020, 12:12pm

There is now a generic service, what do you want me to go through?

Try with the generic mode to list the available services, from there I could try to fix the Xiaomi mode.
