The latest version of the AMBE 3000 Server is located heÂ*
http://ambeboard.zumradio.com/firmware/

That zip file contains the zumambev1.3.bin firmware as well as the program
used to upload to the ESP32 chip on the board.

Open Device Manger and observe what COM port shows up when the AMBE Server
is plugged into the a USB port
Copy the zumambev1.3.bin firmware and the esptool.exe programming tool to
your user space (C:\Users\????? ==Whatever it is)
Open a CMD window
Type esptool.exe chip esp32 port COM3 baud 921000 write_flash 0
zumambev1.3.binÂ* Â* (whatever the COM port should be, 3 in my case)
Wait for it to finish, about 30 seconds in my case


This is the output you will see in the command window:

C:\Users\Bobesptool.exe chip esp32 port COM3 baud 921000 write_flash 0
zumambev1.3.bin

esptool.py v2.1

Connecting.

Chip is ESP32D0WDQ6 (revision (unknown 0xa))
