Connection lost loop

[pristis]

Hello!

I have an issue with the script. I am using this command to get data from my temp and hum sensor:

python3.9 LYWSD03MMC.py -d A4:C1:38:B4:48:55 -r -b

And the answer from console is always this loop:

Trying to connect to A4:C1:38:B4:48:55
Connection lost
Waiting...
Trying to connect to A4:C1:38:B4:48:55
Connection lost

I can connect with gatttool -I with no issues, but with LYWSD03MMC.py I can't find a solution.

I will be glad for some help. Thanks for your time.

Hi pristis,

which Firmware are you using? If not already ATC Firmware von there https://github.com/pvvx/ATC_MiThermometer I recommend using this Firmware. Connection mode is not recommended any more and support will be removed in a future version.

hello, while trying to connect the sensor to domoticz, I updated the sensor. When trying to change the software, I get the message

Will he be able to change the software version in some way?

I have strange issue, 5 sensors works perfectly (3 pcs on RPI4, 2 pcs on RPI0).
Bought next 4 and I'm trying to connect it without luck.

The diffrence is in value coding 0x0033 for new one vs 0x0036 for old one.
