Ebyte E32 Lora Module - Transfer Files

2021-06-18 hardware lora wireless ebyte-e32-lora

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.

receiver$ e32 -s # make sure this is good
receiver$ e32 --out-file f
waiting for input from terminal

Sending a file

We can transmit the contents of a file:

transmitter$ e32 -s # make sure this is good
transmitter$ cat f
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxyy
transmitter$ e32 --in-file f
waiting for input from terminal
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxyy
transmitter$

Viewing the Contents

receiver$ cat f
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxyy
