ArduinoOTA GET with SAMD

SReibert · February 8, 2020, 3:09pm

Hello,

I have a self build Board with SAMD21 and W5500 Ethernet.
I need a firmware update over Ethernet. The board must load the file from a server and not push the code from the Arduino IDE.

So I found a library: GitHub - JAndrassy/ArduinoOTA: Arduino library to upload sketch over network to Arduino board with WiFi or Ethernet libraries

The library support the SAMD21 but only push Code from Arduino IDE.

I become the tip that I can use the GET request to download the file and the InternalStorage object of the ArduinoOTA to store and apply the downloaded binary.

The GET request I understand but how I use the InternalStorage object and in combination that it works I dont know.

Can everyone give me a example how it works?

Regards
Steffen

here is how the server in OTA library processes the upload. you will process the download in very similar way

github.com

arduino-libraries/WiFi101OTA/blob/2403f98d93f1500772cb2c7e4e33d1efce9f87b5/src/WiFi101OTA.cpp#L242


      
              0x00, 0x00, 0x00, 0x78, // TTL
              0x00, 0x04,
              0xff, 0xff, 0xff, 0xff // IP
            };
            memcpy(&aRecord[sizeof(aRecord) - 4], &localIp, sizeof(localIp));
            _mdnsSocket.write(aRecord, sizeof(aRecord));
          
          
  _mdnsSocket.endPacket();
          }
          
          
void WiFiOTAClass::pollServer()
          {
            WiFiClient client = _server.available();
          
          
  if (client) {
              String request = client.readStringUntil('\n');
              request.trim();
          
          
    String header;
              long contentLength = -1;
              String authorization;

Sorry I dont get it

If anyone have the time to code this I had write a new topic:

Thanks

/*

 This example downloads sketch update over network.
 It doesn't start the OTA upload sever of the ArduinoOTA library,
 it only uses the InternalStorage object of the library
 to store and apply the downloaded binary file.

 To create the bin file for update of a SAMD board (except of M0),
 use in Arduino IDE command "Export compiled binary".
 To create a bin file for AVR boards see the instructions in README.MD.
 To try this example, you should have a web server where you put
 the binary update.
 Modify the constants below to match your configuration.
