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...

Examples

Embodiment Construction

[0023] The following will be described in detail by means of specific embodiments, when it is easier to understand the purpose, technical content, characteristics and effects of the present invention.

[0024] The present invention provides a method for updating firmware by using the object push mode in the Bluetooth object exchange protocol, which is to use the OBEX object push mode (OBEX Object PushProfile) in the Bluetooth (Bluetooth) to pass the new program code in the host terminal through a The software program of the electronic device with bluetooth is written into the flash memory of the bluetooth electronic device, and the old program code is cleared, so the space of the flash memory can be saved compared with the known technology.

[0025] like figure 2 As shown, a bluetooth electronic device 18 wants to update the firmware, and the new program code of the firmware is stored in a host terminal 16. This host terminal 16 can be a device with functions such as storage ...
