![]() ![]() I tried googling the answer to this issue on my own however all that comes up is "make sure the device is on the same network" and that's the only answer that I can find. I navigate to the ip address on either my phone or computer and they both tell me this site cant be reached. Now I have it all setup and ready to go I uploaded the code to the board and the serial told me Wifi Connected, ip address 192.168.1.12 It worked in the end though, kind of.So I have brought a NodeMCU and I am just trying to get a basic project to work over wifi. That meant I had to navigate to the nodemcu-tool directory in node_modeules and call nodemcu-tool.js directly. There were mac permission problems that I didn’t end up fixing, just running it locally, not globally. I ended up having to install node.js and a load of other stuff. lua files to your Huzzah, which is great. NodeMCU-Tool was a bastard to install though. I also had a go at setting up a cative portal/http server from here Rather than use CoolTerm it requires NodeMCU-Tool, which just runs in terminal and allows you to upload. I had some fun setting up a soft access point using the wifi module. Click the rest button and you should be off and away with a upgraded version of NodeMCU. Click Flash.īack in Coolterm set the baudrate to 57600 as changed in this version. I variously wiped the firmware and didn’t, it’s up to you. The Huzzah is Dual Flash I/O so set that if it’s not already. When you get the email save the float.bin file somewhere then browse to it in NodeMCU PyFlasher ‘NodeMCU firmware’ box. I added Wi-Fi as I wanted to set up an access point. This can be custom built for you at Select the master build and add any other modules you like the sound of. ![]() I just needed to download the latest version of NodeMCU. Set the baud rate to 921600 too, as above. The easiest way to update the firmware, I found, was to follow these instructions and use NodeMCU PyFlasher. This might sound like I know what I’m talking about, but I don’t. Node MCU is the firmware platform that uses the Lua scripting language. Updating the build of NodeMCU seemed like a good idea too, as the firmware build seemed like quite an old one. I didn’t mess with any of the other settings then just pressed the reset button on the board and it connected. The build that comes loaded onto the Huzzah works at a baudrate of 9600, so change that too. You shoudl see SLAB_USBtoUART as an available port, select that. Plug in the ESP 8266 and launch cool term. Once the drivers were installed and the cool term was up and running it is worth checking that you have a connection. Next I need a terminal to communicate with teh ESP8266. There was some mac related jiggery pokery that meant that I had to go into system preferences and Security and Privacy to get the drivers to work. I followed these instructions that tell you where to download the drivers from. Before I could interact with it I needed to install the USB > COM drivers. I just bought an Adafruit Feather Huzzah, an all in one development board that could be hooked up to usb. It took me a while to get started so I’m sharing my super basic intro here. During a residency at Signal Culture, during which I wanted to make a wearable network point, I had time to play with one. I came across these tiny Wi-Fi modules thanks to Brett Balogh’s Wilderness Wireless project presented at Radical Networks. ![]()
