Send Images over MySensors and Arducam possible?

Hi!
It is possible, to connect an ArduinoCam 2MP with ISP-Port to a MySensors-Arduino Board, to send Images to the MySensors-Controller?

@cablesky it seems to be possible according to https://forum.mysensors.org/topic/1668/sending-image-data-over-the-mysensors-network/

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Thers is actually support for pjon as transport in MySensors: https://github.com/mysensors/MySensors/pull/1278 I don’t know how it works though.

MySensors is an EXCELLENT project. It allows for complete control over the various sensors. It's extremely simple. Its drawback is that it's open source, so it's unfunded and development is slow, but I don't think there are any better projects than this at the moment.

I don't have a good answer for you @mimaret When I get to the point where I'm getting strange error messages, I bite the bullet and start from ground zero. Fortunately, with the RPi you just need a new SD card. Start with a fresh copy of the Raspberry Pi OS. If you enable SSH (and WiFI) when you create the image, you can do everything headless (without keyboard-mouse-video) by running raspi-config via a remote terminal ( PuTTY ) If you enable VNC with raspi-config you can have access to the GUI. Double check your radio wiring. Don't have anything unnecessary plugged in. Carefully follow the instructions I've done this tedious process many times. My RPi's are 3B+ and Zero 2 W. Here's what I've encountered: bad power supply bad SD card bad wiring corrupt download and, of course, more user errors than I care to think about! I have not come across bad RPi ... no, not true! I had a Zero 2 W with a bad WiFi chip (common problem). Overcame that with a USB WiFi dongle. Good luck! Let us know what you discover. -OSD

@sandorhoffmann I hope there is someone that can answer your question. But, I really recommend using DHCP. In that way, you can control all of your IPaddresses in one place, your DHCP server (almost always, your router) The huge advantage of ESP devices over Arduino is the WiFi. You don't need a big library. The MAC address is hard coded at the factory. I'm not sure that you can change it, which you would want to do if a device failed and you need an EXACT replacement. The downside of ESP is also the WiFi. Most home routers can only handle 20-30 WiFi devices My Asus routers start dropping WiFi devices resulting in difficult reconnects. The network becomes unusable. Because I have many ESP devices, I employed a Ubiquity access point that can handle 300 WiFi devices. The routers can handle 254 (253?) IP assignments, though some only allow 64 DHCP assignments. There is a discussion on this forum someplace on the number of clients there can be in a MySensors network. In theory 254 (253?) is the max, though I am unaware if anyone has tested it. I use an RPi as my gateway and haven't had problems with too many devices. If one is considering a very large number I would recommend starting each sensors one at a time because the gateway way will assign the NodeID which gets written into location 0 of the EEPROM. Or burn a NodeID into the Arduino EEPROM before running the actual code. bottom line, you didn't do anything wrong, its the nature of the beast.
