AttributeTypeOptionalDescription
downloadUrlStringNoThe download address of the new firmware, only supports the HTTP protocol, the HTTP server must support the Range request header.
sha256sumStringNoSHA256 checksum (hash) of the new firmware, it is used to verify the integrity of the new firmware downloaded

The following failure codes are added to the error field of the response body:

– 403: The operation failed and the OTA function was not unlocked. The interface “3.2.6 OTA function unlocking” must be successfully called first.

– 408: The operation failed and the pre-download firmware timed out. You can try to call this interface again after optimizing the network environment or increasing the network speed.

– 413: The operation failed and the request body size is too large. The size of the new OTA firmware exceeds the firmware size limit allowed by the device.

– 424: The operation failed and the firmware could not be downloaded. The URL address is unreachable (IP address is unreachable, HTTP protocol is unreachable, firmware does not exist, server does not support Range request header, etc.)

– 471: The operation failed and the firmware integrity check failed. The SHA256 checksum of the downloaded new firmware does not match the value of the request body’s sha256sum field. Restarting the device will cause bricking issue.

Note:

  • The maximum firmware size is 508KB.

  • The SPI flash read mode must be DOUT.
