Abstract
A method of updating firmware using the object push profile in the bluetooth object exchange protocol is proposed. This method first makes use of a bluetooth transmitter to connect a bluetooth electronic device whose firmware is to be updated and a host storing a new program code. Next, the bluetooth transmitter checks parameters in an EEPROM of the bluetooth electronic device to determine whether it is necessary to update the firmware. Through the object push profile (OPP) in the object exchange (OBEX) protocol of the bluetooth technology, this new program code is reprogrammed to a flash memory in the bluetooth electronic device. After the end of the reprogramming action, the bluetooth connection between the bluetooth electronic device and the host is cut off to finish firmware update of the bluetooth electronic device.
