Firmware updating method and device

Abstract

The embodiment of the invention provides a firmware updating method and device. The method comprises the steps of acquiring updated version information of firmware; determining a target data block forthe firmware of the updated version; sending an acquisition request for the target data block to a server based on a CoAP protocol; receiving a target data block returned by the server based on a CoAP protocol; judging whether a next data block for the firmware of the updated version exists or not; ifyes, returning to the step of determining the target data block for the firmware of the updated version, the target data block being the next data block; if not, it is determined that downloading of the firmware of the updated version is completed. The embodiment of the invention provides a firmware updating mode based on a CoAP protocol, so that a terminal gets rid of dependence on a TCP protocol, and the terminal which does not support the TCP protocol can also normally realize firmware updating. Moreover, the CoAP protocol is customized for the Internet of Things equipment with limited resources, so that the resource occupation is extremely small, and the network anti-interference performance is high.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a firmware update method and a firmware update device. Background technique [0002] FOTA (Firmware Over-The-Air) is a firmware update method suitable for IoT terminals. [0003] In the traditional FOTA firmware update method, the firmware download is based on the TCP (Transmission Control Protocol, Transmission Control Protocol) protocol, and the version query and progress report also need to be based on a separate protocol, such as TCP, CoAP (Constrained Application Protocol, restricted application protocol) , MQTT (Message Queuing Telemetry Transport, Message Queuing Telemetry Transport), etc. This makes the Internet of Things terminal need to support multiple network protocols, and it is required to support the TCP protocol. [0004] Since the FOTA firmware update method needs to be supported by multiple network protocols, the code size of the FOTA incr...

Problems solved by technology

[0004] Since the FOTA firmware update method needs to be supported by multiple network protocols, the code size of FOTA increases

On the other hand, many IoT terminals on the market that emphasize low power consumption and low cost do not support the TCP protocol and do not have enough resources to implement the TCP protocol and other protocols. On such devices, the conventional FOTA firmware update method cannot be implemented.
