Method for updating tough body utilizing object propelling mode in blue-tooth object exchange protocol

Abstract

The present invention provides a method for innovating tough body by utilizing object push profile (OPP) in Bluetooth object exchange (OBEX) protocol. Said method includes the following steps: utilizing a Bluetooth transmission device to make a Bluetooth electronic device with tough body to be innovated be connected with a main machine terminal in which a new program code is stored, then utilizing said Bluetooth transmission device to check the parameters in EEPROM of said Bluetooth electronic device and judge that the tough body has need of innovation or not, and utilizing object push profile (OPP) in Bluetooth object exchange (OBEX) protocol to reprogram said new program code into a flash memory in said Bluetooth electronic device, after the reprogram action is completed, interrupting online state of said Bluetooth electronic device and said main machine terminal, so that the tough body innovation of said Bluetooth electronic device can be implemented.

Description

technical field [0001] The invention relates to a method for updating a remote program by using bluetooth, in particular to a method for updating a remote program in an object push mode by using an object exchange protocol. Background technique [0002] With the rapid development of science and technology, electronic products are also constantly upgraded. In order to achieve interoperability among products with the same function, most electronic products need to update their firmware. Bluetooth products include mobile phones, earphones, Dongle, and hands-free handsets for cars. Unavoidably, there is a need to update the firmware. [0003] In the known technology, when the firmware needs to be updated, the entire electronic product must be sent back to the original factory, and the new program code is burned on the flash memory. The new and old program codes occupy the memory space at the same time, so it consumes a lot of memory resources, and the firmware can only be upgra...

[0003] In the known technology, when the firmware needs to be updated, the entire electronic product must be sent back to the original factory, and the new program code is burned on the flash memory. The new and old program codes occupy the memory space at the same time, so it consumes a lot of memory resources, and the firmware can only be upgraded after sending it back to the original factory. Users need to upgrade the firmware of electronic products by themselves through wired transmission devices such as RS232, USB, and printer ports, and then use the application software provided by the manufacturer to reprogram the firmware. Currently, Bluetooth products that allow users to upgrade their firmware wirelessly Only Dongle, such as figure 1 As shown, since the Dongle 14 is connected to the USB port of the personal computer 10, the firmware of the Bluetooth electronic device 12 can be updated by using USB bidirectional transmission, but other Bluetooth products cannot use USB actions like the Dongle, such as earphones, Its volume is very small, and there is no extra space for USB connection. It is also like a hands-free handset for a car. Its Bluetooth function is directly integrated on the main circuit board of the car, so it is difficult to update the firmware easily.
