The present invention is applicable to the communication field, and provides a method and device for modifying the firmware of an external device. The method includes: the terminal device receives an instruction for modifying the firmware of the external device and encapsulates it into a data packet, and the instruction includes the data to be modified. The data packet includes a command identifier that can distinguish the audio signal; the terminal device encodes the data packet and converts it into a pulse signal, and sends it to the external device through the audio interface; the external device receives the data packet and triggers it by reading the command identifier The operation of changing the firmware of the external device; in response to the operation of changing the firmware of the external device, the data packet is decoded and converted into a binary stream, and corresponding data is changed. The technical solution provided by the present invention overcomes the defects in the prior art that can only rely on the USB interface for firmware modification, makes firmware modification more convenient, and also verifies the modified data, further speeds up the rate of firmware modification, and at the same time enhances the The accuracy of the change.
Description
technical field [0001] The invention belongs to the field of communication, and in particular relates to a method and a device for changing firmware of external equipment. Background technique [0002] With the intelligentization of mobile terminals, the external devices that communicate with the mobile intelligent terminals have also achieved breakthrough development. The update of external devices is very fast, and the firmware needs to be continuously updated. The firmware update of the external device of the current mobile smart terminal requires the device to be connected to a computer or a mobile smart terminal through a USB interface for updating or modification. [0003] In the prior art, the update or modification of the firmware of external devices needs to rely on the USB interface of the terminal equipment. The mobile intelligent terminal needs to use the USB interface when charging or data transmission, so that the USB interface is often in an occupied state. Th...
