I am currently developing an IoT device with arduino and i want to minimise the data payload. First i used json which is not very efficent in fixed messages (the format will always be the same). Then i found something like messagepack which also sounds nice but i think you could do even better with just binary. I hope to find something like that:
I have a message for example:
The position of this variables never change so i could represent the message in binary and i could save a lot of bytes. Is there any library which can de/encode such formats and generate messages from given values?
If not i think it would be very useful in further IoT devices!
