HTTP/HTTPS OTA#

1. Purpose / Scope#

This application demonstrates how to update new firmware to RS9116W EVK using remote HTTP/s server or cloud storage server.

In this application, RS9116W EVK connects to Access Point as HTTP/HTTPS client and establishes connection with HTTP/s server (Apache server) or the cloud storage server (i.e., AWS S3 bucket/Azure Blob storage). After successful HTTP/s connection, RS9116W EVK sends firmware file request (HTTP GET Request) to remote server and server responds with Firmware file.

The server transferred firmware file gets loaded/updated in the RS9116 module flash memory. After successful firmware update, HTTP/s OTA API returns success response.

#define RSI_EXT_TCPIP_FEATURE_BITMAP (EXT_FEAT_HTTP_OTAF_SUPPORT | EXT_TCP_IP_SSL_16K_RECORD)

4.3 To Load Certificate#

rsi_wlan_set_certificate() API expects the certificate in the form of linear array. Convert the pem certificate into linear array form using python script provided in the SDK <SDK>/resources/certificates/certificate_script.py.

For example : If the certificate is ca-certificate.pem, enter the command in the following way: python certificate_script.py ca-certificate.pem The script will generate ca-certificate.pem in which one linear array named ca-certificate contains the certificate.

Root CA certificate needs to be converted as mentioned above.

After the conversion, place the converted file in <SDK>/resources/certificates/ path and include the certificate file in rsi_http_otaf_app.c

For firmware download using HTTPs Apache server, replace the below certificate include in application

 // Certificate includes
 #include "cacert.pem"
 Replace the certificate in `rsi_wlan_set_certificate()` API in the application with the converted pem array.
 
 // Load Security Certificates
 status = rsi_wlan_set_certificate(RSI_SSL_CA_CERTIFICATE, cacert, (sizeof(cacert) - 1));

Note: For AWS S3/Azure Blob storage use the certificate "http_baltimore_ca.pem.h" included in release pacakge for SSL connection.

6.4 Configuring and Uploading Firmware on Apache HTTPs:#

HTTPs Sever configuration for Apache requires Wamp server, if you have not installed it, follow the "Step 1: Download and Install Wamp-Apache Server" step and continue with the HTTPS steps in this document.

  • Download and Install OPENSSL for windows

    • OpenSSL for windows from here (https://slproweb.com/products/Win32OpenSSL.html).

    • Do default install for OpenSSL.

    • We can only run OpenSSL using command prompt, for that we need to first find the openssl.exe file.

    • Normally it will be in "C:\Program Files\OpenSSL-Win64\bin\openssl.exe"

  • Generate required certs

    Note: If you already have the reqired certs to run the server then, skip the Generate required certs step, copy your certs to C:\wamp64\bin\apache\apache2.4.46\conf directory and update the httpd-ssl.conf file with these certificate paths shown in HTTPD Configuration step.

    • Open Command Prompt in Administrator privilege's.

    • Change directory to your openssl.exe file "cd C:\Program Files\OpenSSL-Win64\bin"

    • Execute the below command to generate a private.key file with AES 256 encryption.

   openssl.exe genrsa -aes256 -out private.key 2048
   openssl.exe rsa -in private.key -out private.key
   openssl.exe req -new -x509 -nodes -sha1 -key private.key -out certificate.crt -days 36500 -config <your-wamp-apache-openssl.conf-file-path>
