OMG doesn't like...

[kroman666]

A story.

I am using OMG for bluetooth detection since years. Two ESP32 are doing their job 24/7 without issues, upgraded to 1.7.0 quite soon after it arrived if I remember correctly.

Suddenly OMG1 was offline, not pingable. After reset, it work for a couple of hours, but then offline again. The TRACE log didn't give a hint and I missed to change to VERBOSE via web.

So I thought, okay, hardware can fail and I flashed another ESP32 with the same configuration. It seemed to work at the beginning, but then it went offline again and OMG2 did the same.

At this point it was hard, I didn't know what's going on. Hardware - already replaced; was the new hardware faulty too? Software - not changed, can be excluded

So 3 hareware faults at a time? As I couldn't believe that, but didn't have other ideas either, I did nothing for a while as I didn't know what to do at all.

What would be your ideas at this step? :)

Okay, I f.. it up, submitted the title unwanted. However, let me proceed.

Then I remembered that I bought a Shelly BLU Button Tough 1 for playing which was somewhere aroung. I changed the log to VERBOSE and saw this at the end:

Since I removed the shelly, both OMG work fine again.

Could you try the development version and let us know if it fixes your issue please https://docs.openmqttgateway.com/dev/

Sure, I installed one OMG with the dev binary via web. No crash so far, since ~2 hours, but I'll wait longer and report again. Btw. is there any reason why the code from the dev version cannot be downloaded from github? Usually I used PlatformIO and my own _env.ini file to program the ESP. So now the difference is that default parameters are used in case this is important.

You should be able to clone the repository, what is preventing you from doing this?

Sorry, I was just searching on the releases page and didn't consider this. So now 2 OMGs were running 1 day, one with 1.7.0 and the other with the development version. The one with 1.7.0 went offline an hour ago while the other is still running. So looks like the dev version doesn't have this problem, even I'm not sure if the crash would have to happen on both at the same time. However, if something new happens, I will let you know.

Unfortunately the problem is not solved with the development version. Seems I didn't recognize immediately because it's rebooting now instead of hanging up.

Could you try the development version of esp32dev-ble-idf. It has more memory for procBLETask.

[kroman666]

Thank you for the hint, indeed this seems to work better, i.e. I see less disconnects on HA. I traced some disconnects and at least not all of them are caused due to resets. For now I will go back to 1.7.0 without the shelly, which is stable setup for the holiday season (I never had disconnects in 1.7.0 before).

Thank you.
