:name: HTTP OTA Firmware Update on SiWx917
3+
:relevant-api: wifi
4+
5+
Demonstrates HTTP/HTTPS OTA firmware update using SiWx917 on Zephyr.
6+
7+
Overview
8+
********
9+
10+
Application demonstrates how to perform HTTP/HTTPS OTA firmware updates on the SiWx917 platform using Zephyr RTOS. It connects to a Wi-Fi network, establishes a secure HTTPS connection using a CA certificate, and downloads firmware updates from a remote server. The application showcases secure connectivity and OTA update mechanisms for IoT devices.
11+
12+
Requirements
13+
************
14+
15+
* SiWx917 development board with Wi-Fi support.
16+
* Windows PC to run HTTP server python script.
17+
18+
Configurations
19+
******************
20+
21+
The following configurations can be modified in src/app_config.h:
22+
23+
* Wi-Fi Settings
24+
* SSID - Network name
25+
* PSK - Network password
26+
* SECURITY_TYPE - wifi security type (0 - no security, 1 - WPA2-PSK security)
27+
* IP_CONFIG - Select IPv4 or IPv6
28+
29+
* HTTP/HTTPS Settings
30+
* HTTPS_SUPPORT - Enable/disable HTTPS (default: enabled)
31+
* HTTP_SERVER_ADDR - Server IP address
32+
* HTTP_URL - To select the file to download
33+
34+
* Firmware Update Settings
35+
* FW_UPDATE_TYPE - Select M4_FW_UPDATE (M4), TA_FW_UPDATE (TA) or Combined update (M4 + TA)
36+
* SECURED_IMAGE_UPDATE - Enable/disable secured image update
37+
38+
* Image File Settings
39+
* For secure updates (SECURED_IMAGE_UPDATE=1), the possible values to set HTTP_URL are:
40+
* SECURE_M4_RPS_FILE - M4 secure image file
41+
* SECURE_TA_RPS_FILE - TA secure image file
42+
* SECURE_COMBINED_RPS_FILE - Combined secure image file
43+
* For non-secure updates (SECURED_IMAGE_UPDATE=0), the possible values to set HTTP_URL are:
44+
* M4_RPS_FILE - M4 image file
45+
* TA_RPS_FILE - TA image file
46+
* COMBINED_RPS_FILE - Combined image file
47+
48+
Building and Running
49+
********************
50+
51+
1. Configure Network Settings
52+
* Update SSID, PSK and SECURITY_TYPE in and src/app_config.h
53+
* Configure server address
54+
* Set IP_CONFIG to IPV4 or IPV6 as needed
55+
56+
2. Configure Update Type
57+
* Set FW_UPDATE_TYPE to:
58+
* Enable/disable secured image update
59+
* Set Image file to download
60+
61+
3. Build and Flash
62+
.. code-block:: console
63+
64+
west build -b siwx917_rb4338a siwx917_https_otaf -p
65+
west flash
66+
67+
4. Run HTTP/HTTPS server
68+
69+
Host Server Setup
70+
****************
71+
72+
1. Python HTTPS Server
73+
.. code-block:: console
74+
75+
cd <server_directory>
76+
python <http/https server script>
77+
78+
2. Server Requirements
79+
* Python 3.13
80+
* server-cert.pem and server-key in server directory
81+
* Firmware files (.rps) in server directory
82+
83+
Test the Application
84+
********************
85+
1. After flashing the SiWx91x, the device will scan for the specified AP and attempt to connect if found.
86+
2. Once connected, the SiWx91x will initiate an HTTPS connection to the specified server and download the firmware binary.
87+
3. The OTA update process will be logged to the serial console.
88+
