Hello all, This is my first post here and I have tried to follow the "getting the best out of this forum". If there is anything that I am missing or can improve dont hesitate to let me know. I am relatively new to using different protocols in order to send data to various controllers and am having…

What do you expect to see and what is it you are seeing. I am thinking a decimal point maybe?

You don't want that delay (2000) at the end of your receiver loop () ( or anywhere else in it )

Thanks for the reply. I am expecting to see 8 in the diameter and 21 as the height.

Appreciate the tip, let me remove those and see what the outcome is.

Sorry thought i'd come back and give a bit more clarity to the issue. I am expecting to see 8 in the diameter and 21 as the height. There should be no decimal point as the value is always a whole number. I am seeing that the values are being sent, but it seems like they are being forced into the bo…

I suggest to get data transmission working properly with example data, after stripping out all the camera and other unrelated code. Then go back and fix the original.

Consider that when a receiver is listening for ESP-Now messages, you may get broadcast messages from other devices that have no idea you're listening. You can't blindly act upon bytes that have been flying through the air. Verifying the sender's MAC is one way to handle this, but is not that flexib…

is it possible the ESP32 and ESP32S3 are packing the structure differently? I also tend to specify integer to be a specific size, e.g. struct __attribute__((packed)) Data { byte NodeID; // ID of transmitting node int16_t seq; // sequence number int32_t distance; int32_t height; } struct1…

Looking at the EloquentCAM library, the variable types for the parameters received from fomo.daemn.whenYouSee are 16-bit unsigned int (uint16_t) variables. However, the struct where you are storing the values uses int which is a signed 16-bit value. eloquentarduino/EloquentEsp32cam/blob/ma…
