6.2 Firmware Upgrade for 3D WiFi Module
a. Copy the folder Upgrade3DWF to SD root directory. The folder includes at least three
files: the configure file (config.txt) and the firmware that needs to be
upgraded(user1.x.x.x.bin and user2.x.x.x.bin, (x means the version number)).
b. The second line ―ESP8266:0/1‖ in the configure file is to control the upgrade of the
WiFi module. As the upgrading signal, 0 means don’t need to upgrade and 1 means need to
upgrade. To be upgraded or not will be detected when the power is on. This signal will be
cleared to 0 after every upgrading. If the upgrading is fail, you can re-copy the folder or
modify the signal as 1. By doing so, when powering on, it will detect that there is a need to
upgrade. The upgrading file will be recorded after the user1 and user 2 respectively with the
format of userx.x.x.x.bin. Wrong file name will lead to upgrading failure or burn an unknown
program to the chip. As the upgrading of ESP8266 uses the method of application upgrading
application, unknown program burnt in the chip will lead to unpredictable result. It won’t be
used again or make any further upgrading.
c. After power on, if no SD card or configure file detected, the USB and WiFi indicator
will flash rapidly in 3 seconds. If there is a SD card but no upgrading file detected, the
