The missing serial library with ack?
Send and recieve any serial data with or without ack.
I was missing any library that could handle ack, so i made my own and wanted to share it to you all.
You can send / recieve vars, arrays, and structs.
And you can send / recieve chunks to. Look at the example.
Tested on arduino pro mini (3.3v), nodeMCU, ESP32 and ESP32-cam.
An example of sending esp32-cam captured image to another esp32 is now added.
The examples have a lot of documentation, so i dont have to explain to much here.
Limits of the Library:Max 254 bytes can be sent / recieved at a time
The protcol is as follows (Packet Anatomy): Header1, Header2, Identifier, RequestAck, SizeofPayload, Payload, Checksum.
Any questions or issues are most welcome.
