![]() Something to connect the XBee to your Arduino.I used Sparkfun’s XBee Explorer USB module, which works great.Something to connect the XBee to your computer.It may work with Series 3 as well, I don’t own any Series 3 XBees so I haven’t tried it yet. The great thing about the S2C is that it has all the Router/Coordinator/API/AT flavors of the firmware bundled together in flash so you don’t need to change the firmware when you want to change operating modes. I have S2C XBees but it should work with the S2B and older Series 2 versions.I first used the pre-built bootloader from the git repo, with a hardcoded 9600 baud rate, then built and tested the atmega328 bootloader at hardcoded rates of 9600, 19200, 38400, 57600, and 115200 baud.Arduino UNO R3 with 5V ATMega328P running at 16MHz.I ultimately went with this because I like how it works both wirelessly and wired, has a pre-built bootloader, supports XBees in API mode and many other features described on his GitHub page. Andrew’s article led me to David Sainty’s XBeeBoot solution.Andrew Rapp, creator of the XBeeArduino library came up with a solution using a second Arduino and an EEPROM.Patrik Jonsson then extended Alan Backlund’s work by modifying the sfxb protocol to be compatible with Series 2 XBees, which he documented in this excellent writeup. Avrdude is what the Arduino IDE uses under the hood to upload compiled sketches to AVR devices such as the ATMega328P chip on the Arduino Uno. Buried in the comments section of the Sparkfun article is a note by Alan Backlund that he ported the sfxb protocol directly into avrdude.Nate at Sparkfun wrote the sfxb_bootloader for Series 1 XBees and documented it with this well-trafficked tutorial back in 2009.The following is a rundown of the sources I reviewed before I ultimately got it working: I had a few false starts but I ultimately got David Sainty’s XBeeBoot working on Windows with a stock Arduino Uno. There are a few guides of varying quality floating around the web explaining how to do this. NOTE: This post isn’t intended to provide every detailed step needed to get things working – you’ll need familiarity with Windows, Linux, C/C++ programming, BASH shell scripting, Arudinos, the Arudino IDE, etc. The following pseudo-walkthrough is based on my notes of how I got it working on Windows, using David Sainty’s XBeeBoot boot loader.īut before we start, a special thank you to David Sainty for answering my questions when I first struggled to get things working. Fortunately, many people around the internet have contributed to making this possible. I had some XBee Series 2 RF modules from Digi and thought, “Wouldn’t it be great to do wireless bootloading with the Arduino so I could ditch the USB cable?”. I soon found out that connecting the Arduino to the PC with a USB cable every time I wanted to upload a new sketch got old very quickly, especially during debugging and testing. Configuring upload protocol.I built a line-following robot a few months back using an Arduino Uno. Here is the output of the attempted upload. Updating toolchain-gccarmnoneeabi 1.70201.0 Updating framework-arduinoespressif8266 1.20400.3 Updating toolchain-gccarmnoneeabi 1.40804.0 The boards still work fine with the Arduino IDE. I sacrificed another board with the same results. Went back to PlatformIO and it would not do an upload to that board any more. Being a 3rd party nano, I used my USBtinyISP and put the stock bootloader on it. I then needed to use Arduino IDE 1.8.5 and compiled something but could not upload it. I received a bunch of nanos last week and used them on platformio, no issues.
