Ebyte e32 Lora Module - Client Socket Examples

Ebyte e32 Lora Module - Client Socket Examples

This post currently has a example client in Python that sends information through Unix Domain Sockets when the e32 is running as a service. Adding clients in other programming languages is a hopeful future addition. See Getting Started.

Prerequisites

Ensure either you have the e32 programming running with sockets enabled. Or, preferred, running as a service.

More background on can be found in e32 sockets.

Ebyte e32 Lora Module - Wiring and Configuring the Raspberry Pi

Sun, 18 Jul 2021 00:00:00 +0000

This post explains how to wire up the UART and the mode pins. We need 5 connections between the Raspberry Pi and EByte E32, as well as a power and a ground. See this software installation after the wiring is complete.

Wiring

Here is the wiring between the E32 and the Raspberry Pi. Please make sure the UART TX of the RPI is wired to the RX of the E32 and vice-versa.

Ebyte E32 Lora Module - systemd service

Ebyte E32 Lora Module - systemd service

The e32 program is intended to be run as a service in the backround with communication through sockets. This way you can write software in any langauge and just have to deal with the easy job of reading and writing to a socket. Once the e32 service is started and running it can be accessed at any time by a client. In this post we’ll document the actual systemd service. We have some client examples demonstrating clients interfacing with the socket.

Ebyte E32 Lora Module - Transfer Files

This post explains how to transfer files over Lora using the e32 program. See getting started for the background.

Prerequisites

We must first assume the e32 is not running as a service. If not sure run a sudo systemctl stop e32 to stop it.

Transferring Files Between two Raspberry Pi Boards

We obviously need at least two Ebyte e32 lora modules for this.

Receiving

From one Raspberry Pi with the e32 installed. We need to be receiving before we transmit the file.

Ebyte e32 - Sockets

Ebyte e32 - Sockets

The e32 program can run as a daemon and listen on Unix Domain Sockets for data to transmit and receive. This post documents the functionality of the sockets the e32 software is listening on.

Intention of the Sockets

The software for the e32 is written in the C Programming Language. I’m a huge fan of C, but it isn’t for everyone, nor, is it for every application. The sockets are created so we can interface any program to the e32. Instead of having to write C code to do what you want, you can just use the e32 as a driver and write a client in any language. When this client writes and reads from the socket it’s transmitting and receiving wireless data. Since the sockets are Unix Domain Sockets they are reliable.
