I'm using E32-TTL-1W wireless modules in a project I'm working on, which uses UART interface. I was able to write a simple code with the help from this tutorial, to communicate with each other. But my real requirements are much heavier than that. Below is the setup in brief.
Gateway - Uses GSM module to receive commands (from long distances). E32 to communicate among the Nodes. GPRS to upload data (gathered from Nodes & it's own) to IoT server. Resends commands 'n' times until acknowledgements received.
Nodes - Use E32 to communicate among the Nodes and the Gateway. Have software IDs. Relay messages (repeater) if RecipientID != ThisID. Send acknowledgements upon message receival. Request data from Gateway.
Is there a library/wireless communication protocol I can use, to handle E32 communication? Is there any sample code that can help me? Your assistance is very much appreciated.
eagle01:
These modules work with SoftwareSerial.h. What I need is a UART protocol to handle the wireless communication.
I already know that they're serial modules, but (as I said before) I doubt there are any libraries for your specific module. You're going to have to do that yourself. I don't think it would be very difficult, just a little tedious.
Pardon me. I was expecting something like MySensors.h. I’m working on the code. I would very much appreciate if you could find me some online help to assist my code development. Thanks.
