Husarnet esp32-internet-ota example

Hannes · January 12, 2022, 2:42pm

I want to update my esp32 over the internet. The esp32 is located in the garden and is connected to a mobile hotspot via wifi.

I found Husarnet via google and have adopted the example (GitHub - husarnet/esp32-internet-ota: ESP32 + GitHub Actions + Husarnet. A boilerplate project for ESP32 allowing in-field firmware update using GitHub Actions workflow.) in my project (Environment VS Code – PlatformIO).

The connection to the Husarnet network has been established. The esp32 is online and I can ping it.

A lot of debugging is generated? Is it normal and can I turn off the debugging outputs?

Unfortunately, I can’t get access to esp32 via Husarnet.

Not even when I try to use the IPv6 address.

Locally, everything works fine.

Instead of using the mobile hotspot, I connected the esp32 to my FritzBox. Does not work too.

Can someone help me?

Hi.
Check HTTP_PORT defined in source code and the one used in your URL.
About verbosity. I asked Dominik one year ago and I’m still waiting a solution.You bad Dominik.

Hi Hannes,

Basically you can perform OTA updates for your ESP32 in two ways:

1. Using GitHub Actions

You need to define 4 GitHub secrets for that and just make a dummy commit to you copy of this repo. Basically before doing anything just click that button:

And make a copy of this repo on your own GitHub profile. Basically do every step shown in the README and you will be fine

2. Using Web UI

At first you need to connect your laptop to the same Husarnet network as your ESP32. You will find available options here: Husarnet Documentation | Husarnet .

After that, from a level of the laptop you have just connected, open the following link in the Firefox web browser: http://parzelle83:8080/update

If you use other browser than firefox, use IPv6 address instead of your ESP32 hostname:

http://[fc94:…:46ff]:8080/update

(of course place the whole IPv6 address here)

Log verbosity

Please take a look at pins that I use in my board for a Serial Interface.

github.com

husarnet/esp32-internet-ota/blob/main/src/simple-webserver.ino#L42


      
          Serial.begin(115200, SERIAL_8N1, 16, 17);  // from P3 & P1 to P16 & P17
          Serial1.begin(115200, SERIAL_8N1, 3, 1);  // remap Serial1 from P9 & P10 to P3 & P1
          
          Serial1.println("\r\n**************************************");
          Serial1.println("GitHub Actions OTA example");
          Serial1.println("**************************************\r\n");
          
          // Init Wi-Fi
          Serial1.printf("📻 1. Connecting to: %s Wi-Fi network ", ssid);
          
          WiFi.mode(WIFI_STA);
          WiFi.begin(ssid, password);
          while (WiFi.status() != WL_CONNECTED) {
            static int cnt = 0;
            delay(500);
            Serial1.print(".");
            cnt++;
            if (cnt > 10) {
              ESP.restart();
            }
          }

I do here a bit of hacking to remap default Serial (where verbose log from Husarnet goes) port to different pins (from P3 & P1 to P16 & P17), and I use Serial1 interface instead (that is now remapped on the standard P3 & P1 pins). You should not see any verbose log, but just this output on the Serial terminal:

@jflopez, that’s also the answer to your previous question about workaround solution for log verbosity . Sorry for delay!

Extra point: this project was made as an example for this article:

https://husarnet.com/blog/introducing-husarnet-action-for-github-actions .

If you don’t understand some concepts or have other questions, you should (I hope) find the answer in this article

In history i solve very similiar problem with Husarnet. In mi case help using AsyncTCP library with ipv6 extensions from husarnet repository and clean dependencies in platformIO.
