judging whether there is any non-transmitted fragment, if so, recalculating the size of the fragment according to the current fragment data transmission condition, and then dynamically adjusting the non-transmitted fragment according to the calculation result.
6. The method of claim 5, wherein recalculating the slice size according to the current slice data transmission condition and then dynamically adjusting the undelivered slices according to the calculation result comprises:
and judging whether the transmission time of the current fragment exceeds the upper limit of the output time threshold range and is less than the lower limit of the output time threshold range, if so, changing the size of the fragment to be half of the size of the current fragment, and if so, changing the size of the fragment to be twice of the size of the current fragment.
7. The method of claim 1, wherein the whole packet check comprises:
and sending a whole package of verification request to the Bluetooth peripheral end, verifying whether the splicing of all the fragments of the transmitted firmware is correct or not, if so, starting upgrading, and otherwise, sending an upgrading failure and/or retry notice.
8. The method according to any one of claims 1 to 7, further comprising:
and in the firmware transmission process, if the firmware transmission interruption is detected, recording the position information of the upgrade breakpoint.
9. A Bluetooth peripheral firmware upgrading system is characterized by comprising an APP end and a Bluetooth peripheral end, wherein the APP end receives a user upgrading request and sends the user upgrading request and an upgrading breakpoint position request to the Bluetooth peripheral end, and the Bluetooth peripheral end returns upgrading confirmation information and upgrading breakpoint position information to the APP end; and the APP end skips to the position of the upgrade breakpoint, performs fragment processing on the firmware according to a preset firmware fragment transmission rule, and transmits the fragmented fragment data to the Bluetooth peripheral end to complete fragment verification, whole packet verification and upgrade in sequence.
10. A mobile phone terminal, characterized in that the mobile phone terminal is configured to: receiving a user upgrading request, sending the user upgrading request and an upgrading breakpoint position request to a Bluetooth peripheral end, and acquiring upgrading confirmation information and upgrading breakpoint position information from the Bluetooth peripheral end; and jumping to the upgrading breakpoint position, carrying out fragment processing on the firmware according to a preset firmware fragment transmission rule, and transmitting the fragmented fragment data to the Bluetooth peripheral end to complete fragment verification, whole packet verification and upgrading in sequence.
