SimpleHTTPUpdater

Library for automatic generated FIRMWARE_BUILD numbers and for retrieving firmware updates from HTTP servers.

Installation (PlatformIO)

Add the following line to your platformio.ini:

lib_deps = https://github.com/sivar2311/SimpleHTTPUpdater

Use

Including the automatically generated version.h

#include "version.h"

Define the download URLs for firmware.bin and firmware.nfo:

const char* firmware_download_url = "http://server/firmware.bin";
const char* firmware_info_url     = "http://server/firmware.nfo";

Initialize the library in setup():

SimpleHTTPUpdate.begin(firmware_download_url, firmware_info_url, FIRMWARE_BUILD);

Call the library's handle function periodically in loop():

SimpleHTTPUpdate.handle();

Note: FIRMWARE_BUILDis defined in version.h and increases automatically on each firmware-build

Compile & Upload to your webserver

Compile your project and upload the new versions of firmware.bin and firmware.h to your webserver.

Using HTTPS

If you'd like to use HTTPS, you can do the following:

WiFiClientSecure client;
client.setCACert("-----BEGIN CERTIFICATE----- your cert here .....");
SimpleHTTPUpdate.setClient(&client);

Example

For details, see the example: HTTPUpdate.ino

How it works (PlatformIO)

The library maks use of PlatformIO scripting and creates and updates automatically the files version.h in your source folder and firmware.nfo in the project folder.

The version number increases on each firmware build.

SimpleHTTPUpdate.handle() checks periodically if new firmware updates are available on the web server. If a higher version is found, it will be downloaded and installed automatically.
