Install the USB driver for your ESP8266 and find out on which port your device is avaible. For convinience you can save that information in your ~/.bashrc or ~/.bash_profile file.
If you don’t wanna do that, you have to add the port to each command.
mos --port /dev/cu.SLAB_USBtoUART COMMAND
Build¶
You need to install Docker to build it locally.
git clone https://github.com/vergissberlin/coffee-bin-mqtt
cd coffee-bin-mqtt
mos build --platform ESP8266 --local --verbose
mos flash --esp-erase-chip --esp-baud-rate 115200 --esp-flash-params "dio,4m,40m"
Debugging and configuration¶
mos wifi --port /dev/cu.SLAB_USBtoUART WIFI-SSID WIFI-PASSWORD
mos console --port /dev/cu.SLAB_USBtoUART
Upload files¶
mos put --port /dev/cu.SLAB_USBtoUART fs/init.js
Requirements¶
Hardware¶
Software¶
- Web browser on Linux, MacOS or Windows
- USB adapter driver (/dev/cu.wchusbserial14610)
- MongooseOS
Configuration¶
