First of all, thank you for this great ESP frameworks (esp-idf, esp-who, etc).
I've just spent a few days playing with them and it's very cool to have all these features running on small ESP32 boards !
I open this issue because I haven't been able to use mdns from the esp-who examples.
How to reproduce the problem
Extra tools I use for my test:
sudo apt install avahi-discover minicom
What did I do :
clone esp-idf(release/v4.4 branch) and install as explained in the doc
clone esp-who
cd exp-who/examples/motion_detection/web
idf.py set-target esp32
idf.py menuconfig and manually setup wifi and camera in esp-who section
idf.py build
idf.py -p /dev/ttyUSB0 flash
minicom -D /dev/ttyUSB0 -b 115200
Now I want to use mdns :
avahi-discover
Problem : it does not see my esp32 device
Problem cause and fix
After investigation, the problem seems to be related to component initialization order in examples :
app_main calls app_mdns_main before register_camera
but app_mdns_main try to fetch the camera properties to initialize itself correctly
