Using the script in "reconnecting mode" leads to crash the bluetooth service

[BlueMorph]

Hi @all,

I've tried the new version of @AnthonyKNorman blemqtt.sh shell script (with the added -c 1 argument at the call of LYWSD03MMC script to support more than one sensor).

After some connections (I only use one sensor) the connection the the xiaomi sensor can't be established. The python script tries to reconnect endlessly. In this state i manually have to reset the bluetooth service by sudo systemctl restart bluetooth.service after this call, the re-execution of the blemqtt.sh script works for some time, before the described error appears again.

Do anyone have the same issues?

[AnthonyKNorman]

I am also experiencing some errors. I will look into it.

[AnthonyKNorman]

I am trying a new tack. I have changed the python script to accept an array of mac addresses. I'll run it overnight and report back.

Hi @AnthonyKNorman ,

what was your experience with your adaption of script?

[AnthonyKNorman]

I have published a fresh version. Is uses a later version of the source script. One notable improvement is that the battery level is actually meaningful. I have not run long term tests yet, but early results seem hopeful. Read.me has been updated. If you would like to test that would be helpful.

Hi @AnthonyKNorman

thanxs for your refreshed version of script.

I tried it with two sensors. Let me show you what happens:

Trying to connect to A4:C1:38:46:B7:2D

The script always tries to connect to only one of the sensors (with the MAC A4:C1:38:46:B7:2D). Seems to be that the loop condition to the next mac-address isn't correct.

This is the content of my LYWSD03MMC_config file: -d A4:C1:38:46:B7:2D,A4:C1:38:82:2D:E3 -r -b 5 -c 1 -m "localhost" -del 120

Maybe my problem is this file. I want to pass all arguments in a kind of argument-file. So no changings to the running service must be done. If I add a sensor I can do it in this argument-file. So my thoughts.

Another thing happens. Do you see the measurements deque output? What happens here?

Okay now I tried to call the LYWSD03MMC.py without my argument file in this way: ./LYWSD03MMC.py -d A4:C1:38:46:B7:2D,A4:C1:38:82:2D:E3 -r -b 5 -c 1 -m "localhost" -del 120

The output is much better. But sometimes is a doubled publish happens. You can see it with the MAC A4:C1:38:82:2D:E3.

Any ideas?

Best regards,

In the first example your config file is -d A4:C1:38:46:B7:2D,A4:C1:38:82:2D:E3 -r -b 5 -c 1 -m "localhost" -del 120 Remove the quotation marks from around localhost. All the parameters are treated as string anyway. MQTT will be trying to connect to '"localhost"' and therefore raising an exception. This means you will exit the loop before the address gets changed. Can you try that and let me know how you get on.

[BlueMorph]

Hi @AnthonyKNorman,

thanks for your hint. This works much better.

But the failure with the stucking bluetooth service is still alive ... :-(

[CSnipper]

Same problem in my home, 5 sensors, after few reads "connection lost" I'm using blemqtt.service and code from it:

ExecStart=/home/pi/LYWSD03MMC.py -d A4:C1:38:ED:80:04,A4:C1:38:08:61:1E,A4:C1:38:A5:B6:D6,A4:C1:38:E0:27:FE,A4:C1:38:8A:A4:DC -r -b 5 -c 1 -m 192.168.1.7 -del 20

[AnthonyKNorman]

I am running two devices. They have been running for several days now. @CSnipper can you post an example of your output when it fails?

[AnthonyKNorman]

You might be interested in my new repository that uses ESP32 instead of Raspberry Pi https://github.com/AnthonyKNorman/Xiaomi_LYWSD03MMC_for_HA

[lukecorkill]

This is great - many thanks.

Got it running very quickly on a spare ESP32.

Luke.
