Over-the-air (OTA) updates

AnyNet SMARTconnect™ supports over the air (OTA) updates for the following software, using parameters set in the configuration file:

• Host
• Kernel (Module operating firmware)
• AnyNet SMARTconnect™ application
• Configuration file

For more information, see Using the AnyNet SMARTconnect™ configuration file.

Updating host firmware

Modify the AnyNet SMARTconnect™ configuration file to contain the URL for the host firmware. The host must request AnyNet SMARTconnect™ to check for updates. If an update is available, AnyNet SMARTconnect™ will download it into flash memory and send a URC to the host, indicating that new firmware is available. The host then reads the firmware image in chunks, using AT commands. A checksum is provided to ensure the copy from AnyNet SMARTconnect™ to host has completed without errors.

For more information, see Updating AnyNet SMARTconnect™ software and host module firmware.

Updating kernel, AnyNet SMARTconnect™ application and configuration software

Trigger updates to the modem kernel, AnyNet SMARTconnect™ application and configuration using either the host, cloud IoT service, or SMS.

The URL used to download the images is set in the AnyNet SMARTconnect™ configuration file. In order to apply updates, AnyNet SMARTconnect™ must reboot. For more information, see update_autoreboot in the configuration file.
