很多人在设置完F9P 想变回出厂状态，不知道如何设置？本文提供了一种常用的恢复方法：
Open the u-center software, select the serial port and baud rate,
first set the correct baud rate. If the baud rate is set incorrectly, the factory settings cannot be restored. For details, please refer to the previous blog (What should I do if I forget the baud rate? )
Open the view, click on the message view
, and then select UBX->CFG->CFG in the pop-up block diagram, as shown in the figure 1, 2, 3
After clicking cfg, the following display box will pop up. Perform steps 4 and 5 to complete the factory reset.
