That what you're most likely looking for is the environment variable EXTRA_COMPONENT_DIRS I've never tested it with multiple external component directories, but at least it works for me reliable for external folder. A folder referenced here behaves similar to the components directory in the environm...

Over 4 months later, still no information on the HALL sensor.

The data sheet doesn't really help that much (even the updated one from May)
What is the range?
Any information on the schematics?
..?

Its a Hitron CGNM0-2250 hardware revision 1A with the firmware 4.5.10.40 Test scenario: Two computers both wait for Multicast message and send every 10 seconds a message. After a while the computers stop receiving message from the other computer. Alternative listen for SSDP(UPNP) multicasts and this...

I did various tests and could track that problem down to the AP. I have no clue what this AP is doing, but I am pretty sure that this firmware has problems. Later on I was able to force the problem with my normal desktop. Checking via Wireshark that IGMP refresh requested gets replied, but still it ...

Performed the described scenario and both were working at all times. Did some additional tests afterwards and tried to get the multicast back to a not working. I enabled 5G again. I was unable get a consistent scenario how to get it back to error state. Did erase the flash, rest it and also removed ...

I tested the mdns example and it seems to do something. I did not check what its doing in detail, but the log contained my printer. So I consider this example as working. Procedure (all based on my normal AP mobile phone AP is not into play anymore) Disable 5G net Connect ESP to 2.4G net Multicast w...

No device is using the 5G AP.

I don't really think that the dual band AP is the problem since the ESP is able to continue to receive message after I enable the 5G again. Only seems to stop working again when I perform a hard reset.

Additional information. Power loss seems to play a role. Both device were not working anymore when I came home today. So I started the enable procedure. Disabled 5G wifi both are working. Enabled 5G again both were still working after I pressed the reset button. One stopped working after 'make flash...

Yes, all tests are done with all devices on the 2,4GHz wifi network.

Should I create a dedicated bug report for this?

No I did not test the mdns example. I've tested a simple tcp/ip server and an UDP sender both work. Now I am seeing the following. The ESP was afterwards able to receive UDP multicasts also on my provider AP. I picked a second ESP32 board with the identical program. It connected to the provider AP a...
