Abstract

The invention provides a wireless upgrade method and apparatus. The method is applied to a wireless device that is in communication connection with a gateway device. The wireless device is separatelypowered by large current and small current within a protocol cycle, the wireless device communicates with the gateway device during the large current power supply, and the wireless device sends a message to the gateway device within the protocol cycle. During the large current power supply, the message is sent to the gateway device, and a reply message is received within a preset waiting time to establish a wireless connection, confirm upgrade start and obtain upgrade mirror image data. Every time when the wireless device obtains a mirror image slice, the wireless device upgrades according toeach mirror image slice. The wireless device repeatedly obtains the mirror image slice until all mirror image slices of the upgrade mirror image data are received. The preset waiting time is smaller than a difference between the protocol cycle and the message sending time. Therefore, the wireless device accomplishes the wireless upgrade in the case of failing to continuously provide the large current.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular, to a wireless upgrading method and device. Background technique

[0002] At present, there is a wireless device remote upgrade solution, although the upgrade can be realized, but there are the following deficiencies in the wireless upgrade. Due to the code setting, the wireless device is always in the state of waiting to receive the message after sending the request message. As a result, the sending or receiving function of the wireless device is always in a working state during the entire protocol period, that is, the wireless device needs to be supplied with a large current during the entire protocol period.

[0003] However, in some special application scenarios, such as single-fire power-taking equipment, small button battery-powered equipment, etc., the power supply of wireless equipment cannot continuously provide high current, or even cannot provide high curr...
