XC4411 Duinotech Classic with Wi-Fi from Jaycar. Many Arduino compatible Mega with WiFi and Uno with WiFi combo boards contain obsolete WiFi firmware that prevents their WiFi working with standard Arduino WiFi libraries. The “AT” command set has been around since the 1981 and is still used in virtually every modem. The standard ESP firmware includes code that converts the venerable ‘AT’ command set into internal ESP machine code, enabling the ESP8266 to send and receive WiFi data packets over the Internet. For the Jaycar Arduino Mega (and Uno) with WiFi, an on-board Espressif ESP8266 IC provides WiFi functionality. Simply put, it remembers instructions, even when switched off.

If you are not aware of what firmware does, firmware is defined as “permanent software programmed into a read-only memory”. PICTURED ABOVE: ISP (In-System Programmer) to be published in Part 2
ESP8266 FIRMWARE ARDUINO HOW TO
Please let me know if this works for you.We show you how to install or upgrade microcontroller firmware to eliminate WiFI errors in some Uno and Mega WiFi combo boards. You should not need to do any more USB updates, unless something goes horribly wrong, or you want to go back to stock NodeMCU firmware. That will get whatever version I have available. For my customized “CoCoWiFi” version, it will pull special builds from my website instead, and there are three different boards supported.Īs I build new versions of this customized Zimodem firmware, I will place them on my server and you can type (from the Zimodem command mode): AT&U=3.4 In stock Zimodem, firmware updates pull from Bo’s website for the two boards he support (the ESP-1, I think, and some flavor of ESP32). You can then use the command “AT&U” to see what the current version is. Make sure you configure your Zimodem for your WiFi network by going through the: AT+CONFIG Once you have this special build of the firmware, you will be able to do over-the-air updates. You can now restart the ESP8266 module and it should be using the new firmware. If it works, you should see something like this: prompt$ esptool.py -p /dev/cu.SLAB_USBtoUART -baud 460800 write_flash -flash_size=detect 0 -3.4.bin On my system: esptool.py -p /dev/cu.SLAB_USBtoUART -baud 460800 write_flash -flash_size=detect 0 -3.4.bin
ESP8266 FIRMWARE ARDUINO SERIAL
Now that you know what serial port is connected to the ESP module, run esptool.py specifying that port, and the firmware image to use. (I also saw an exemple using “setserial -g /dev/ttyS”). On Linux, I think you need to do ls /dev/ttyS*. (On my system, I know I installed Silicon Labs drivers, so I recognized the “SLAB” name.) If you do not know what to look for, you could do this command before plugging in the ESP8266, then again after you plug it in and see what appears. dev/cu.Bluetooth-Incoming-Port /dev/cu.HC-05A-DevB /dev/cu.SLAB_USBtoUART On Mac, can look for devices that begin with “cu”: alsmbpro:temp allenh$ ls /dev/cu* This can be done from a shell (Linux) or the Terminal (Mac). Identify the serial port connected to the ESP module. NOTE: I think I hadto run this as super user, “sudo easy_install esptool”. Install esptool (a Python script) and pySerial (a Python library for talking to the serial port): easy_install esptool
