Device settings
This settings panel is backed by the "settings" dashboard object see Dashboard.init call at the top of index.html - and, consequently, by the "settings" fieldset in mongoose_dashboard.c.
Fields are bound to the dashboard object via the data-bind attribute, e.g. data-bind="setttings.name"
When you save changed fields, the changes are saved to the device.
The "NAME" field has data-autosave="1", so it is autosaved when user types text.
The other fields are not auto-saved, so when they are changed, dashboard.js automatically applies CSS class "edited" to them to indicate they were changed but not saved.
The cancel and save buttons are attached to the settings object via the data-cancel and data-save attributes. Those buttons get automatically enabled or disabled based on editing status.
Firmware update via file upload
Current firmware version
${settings.ota_version}
Upload new firmware
This firmware update method is the simplest. Just select your
`firmware.bin` file and upload it.
Mongoose includes built-in firmware update support for many
architectures, such as STM32, RP2040, and ESP32. See
ota.h
for the full list of supported MCUs.
If you are using STM32, it works out of the box with no additional setup.
For other architectures, add `#define MG_OTA MG_OTA_XXX` to your
mongoose_config.h.
Firmware update via periodic URL check
Current firmware version
${settings.ota_version}
Current status
${settings.ota_status}
Check interval, seconds
URL
With this mechanism, you can configure an entire device fleet to update
automatically. Upload your firmware .bin to a web server and create a
JSON file that describes the firmware, including its URL, checksum, and
size. Mongoose periodically checks this JSON file, and if the version
differs from the current one, it downloads the firmware and performs the
update. The JSON file format is described in the
docs:
{
"version": "1.2.3",
"url": "http://my-product.com/firmwares/firmware-1.2.3.bin",
"size": 324645
}
The two default files are fake - you can delete them
However the manager works - you can upload new files. They are uploaded to /tmp/ directory on the device. This requires stdio (fopen/fread/...) implemeneted.
The easiest way to implement it is to use a filesystem like LittleFS on your internal or external flash and retarget the standard library to use it.
See this example on how LittleFS can be implemented on Nucleo-H563ZI internal flash partition.
