Firmware Update

6.1 Microcontroller Board

To update or change the microcontroller firmware, the board has to be connected to the PC via the
USB port. It opens a new mass storage device called NODE_F303RE.
Just drag and drop the .bin file on that device. LD1 on the board starts flashing red and green. As
soon as the flashing stops, the board is programmed and after a reset the new firmware should be
running.

6.2 WiFi Module

Connect the sensor using a 3.3V USB to UART cable like shown in the below figure. Make sure
cable TX is connected to WR (wireless RX) and cable RX is connected to WT (wireless TX). Switch
SW1 to the PROG position.

Figure 6

Jumper settings and program select switch for the WiFi module.

Edit the batch file run_esptool.bat under Install_Package\WiFi Module\websocket_mini and replace
COM7 with your com port setting for the USB to UART cable.
