Hey! :) You can search online for waveshare ov2640 and you will find a module with the camera and two row header. This will let you easily connect the camera to your board, but please be noted that your board does not have PSRAM and this will limit much what you can do with the camera. I advise you ...

While iOS will be definitely fully supported (Desktop also), as of now they are not so much. If you can have an Android emulator be able to access your BT in the Mac, then you could probably try that.the bulb and it's board are capsulated and filled with some sort of technical cement, so you do not ...

Sorry, I personally have no idea about possible channels to obtain the bulbs, but I am pretty sure that Mouser has them also. You flash the bulbs through the Android App, which does it in the OTA fashion, so no pins are required :) Arduino is not yet supporting the full MDF. Once all heavy developme...

Why do you use String to collect byte data? Not all bytes are printable chars. Did you try to ask around in the PubSub repository?

Please post your issue in the Arduino tracker https://github.com/espressif/arduino-esp32/issues and also post a clear info on what is not working, what messages are you getting in the console and wether you have debug enabled or not.

In the case of this demo, yes, every light is flashed with mqtt capable firmware. MQTT is already in IDF, so building a mesh firmware with added support is easy :) Unless you force a node to not be master (or you force particular one to be master), all nodes must be capable of MQTT else you can not ...

In this demo, the PI/MQTT only collects the information, though adding control through it is not any different than other MQTT implementations. Each MESH device in this case has the code required for it to talk to MQTT if it is the Mesh Master. The same way that the master publishes the updated info...

I hope it helps

@dldtechnology That is an interesting find! One would think that when you write to the register, the data will latch :) And I did not read anything in the bus specs to give the idea that such check should be performed. Another issue that I'm looking at is clock stretching with some slaves to timeout...
