SuperGreenOSBoilerplate | ESP32 Boilerplate code generator - See README -

Follow the [get-started guide from espressif](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/). Install [cuelang getting started](https://cuelang.org/docs/install/). Cue is a tool made to write JSON configurations in a much more efficient manner. And finally, install [ejs-cli](https://github.com/fnobi/ejs-cli).
As an example we’re just going to stream a temp sensor’s values to a cloud, for monitoring and alerts. We’ll also blink a led based on said sensor values (the hotter the faster it blinks). The sensor used here is the sht21, I’ll pass the detail because it’s a weird one, but it’s i2c compatible, and I have the code here. This will get us through the main features: - create a module - create an i2c device - initialize the key in the system.
At that point we want to see our key available over ble and http, right ?. So plug in your esp32, set the right serial port by doing a make menuconfig and under Serial flasher config → Default serial port you’ll be able to set the port. Finding the right port depends on your system, on mine (debian) it’s /dev/ttyUSBX, X being 0 for small esp32 boards, and should be 1 when using the esp-wrover-kit. On macosx I had to change the python version used too, explicitely set python2 under SDK tool configuration → Python 2 interpreter. After some uploading, you should see all the esp’s logs (in green) appearing on your screen. Now there are two options to do the initial setup, by connecting either to its wifi or ble inteface.
There is a key pre-configured to set the mqtt broker url: BROKER_URL, it’s only accessible through wifi. To change it’s value:. Restarting is required for changes to take effect (removing this is on the TODO). Now you should start seeing logs arriving in prometheus and grafana.
