3.3.1

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 in the Windows Explorer. Drag and drop the .bin file that
you want to flash 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. Alternatively, you can use ST-LINK
Utility to flash the firmware on the microcontroller board.

3.3.2

WiFi Module

Connect the SiRad Easy® using a Serial/USB (FTDI) cable or Serial/USB adapter as shown in Figure 11 using the
external header (J1). Please read Section 3.2 about the external header connection. Then connect cable TX to WR
(WiFi RX) and cable RX to WT (WiFi TX).

Make sure to use a cable with 3.3V TTL levels!

Switch SW1 to the PROG position.

Download esptool. Copy the desired firmware into a folder together with esptool. Edit the batch file esptool.bat
and replace the COM port with the COM port of your Serial/USB (FTDI) cable or Serial/USB adapter and the
firmware name with the desired firmware, for example:

esptool -bz 1M -cp COMx -cf websocket_mini.ino.generic.bin

The  baud  rate  for  flashing  the  firmware  needs  to  be  1  Mbaud.  Run  the  batch  file  and  the  WiFi  module  gets
programmed, indicated by a flashing blue LED.  The programming is finished after about 40 seconds. Switch the
DIP  switch  WP  back  to  the  OFF  position  and  connect  a  jumper  between  MT  and  WR  and  MR  and  WT  on  the
external header (J1).

3.3.3

USB Controller Firmware

Download and extract the ST-LINK firmware update tool. Go into the AllPlatforms folder and start the .jar file.
Connect the SiRad Easy®, click Refresh device list and then Open in update mode to see the current USB controller
firmware. Click Upgrade to flash it to the latest version.
