Here is a BLE firmware without the WebUI, as the issue seems to appears when sending data to the WebUI. Could you try it ?

To update:

  1. Download the firmware from here and unzip it from the smartphone/computer you are going to use to connect to the ESP32

  2. Erase the ESP32 within the WebUI (Configuration-> Reset configuration)

  3. Connect to the Web portal access point from your smartphone/computer

  4. Click Update, select the firmware file and wait a few minutes until you get “Update successfull”

  5. Reconfigure the board into the Web portal access point

24

It’s running now. I will report back.

It’s still throwing exceptions:

It’s throwing an exception at scan 28. I have bleconnect set to false.

27

@1technophile It’s been throwing exceptions randomly. Any other ideas?

28

@1technophile I hope you can get the instability figured out. I like the idea of a multiprotocol gateway but the instability is a serious problem. I have two other identical ESP32 modules running TasmotaBLE listening to the same devices that haven’t reset at all.

29

Hi @pwm802,

Which BLE devices do you have that you are receiving and decoding with OpenMQTTGateway? I’m wondering if it has to do with a specific device decoding issue.

Also, do you you a white-list to restrict the decoding of only your devices? As possibly some neighbour’s or passing devices might cause this? If you are not using a white-list would you mind setting one, restricted to the MAC addresses of your own devices, to see if the behaviour changes at all?

My issue is that I don’t reproduce this.
I need to flash my LYWSD03MMC with the same version as yours but it will take time due to the holiday time.

I have some other non sensor BLE devices within range of the OpenMQTT and TasmotaBLE modules. I will set up a whitelist of the LYWSD03MMC sensors and retest.

32

@1technophile @DigiH Based on what I saw on forum posting, I tried to setup a white list via MQTT and I did not see any response from the device in the console or MQTT. It does not appear to use the white list after publishing the list via MQTT.

Here is what I sent via MQTT.fx:

home/OpenMQTTGateway/commands/MQTTtoBT/config

{“white-list” : [“A4:C1:38:00:XX:XX”, “A4:C1:38:63:XX:XX”, “A4:C1:38:D7:XX:XX”, “A4:C1:38:12:XX:XX”]}

I’m clearly missing something.

33

I’m pretty sure your gateway name is different to the example default OpenMQTTGateway :wink:

You can see the correct gateway name in the incoming topic of the MQTT messages, usually depending on which binary you installed.

34

Yes indeed. Too much cut and paste.

35

@DigiH @1technophile It’s still throwing exceptions with the white list.

36

@1technophile Did you ever get around to flashing that LYWSD03MMC firmware?

37

Not yet, let me try I will update here

38

I have updated to version 4.6

4:31:20 PM: Hardware Version: LYWSD03MMC B1.4, Software Version: 4.6, Sensor: SHTC3 (SHTV3)
4:31:20 PM: Custom config HEX string: 55851000002802a9313180b400

And don’t have restarts for now

39

If you are not having restarts then I guess the other non sensor BLE devices in range might be the causing the restarts but even with a whitelist, it would reset.

40

Did you try to update your LYWSD03MMC?

41

I will try updating the LYWSD03MMC firmware next week.
