ESP8266

ESP8266 basic example for Azure IoT Central

• Visit AzureIoTCentral and create a new application.
• Select Sample Devkits
• Add a new mxchip device. (a real device) (under Device Explorer)
• Browse into device UI (by clicking to name of the device under Device explorer)
• Click/open Connect at top-right of the device UI
• Grab scopeId, device Id and primary key and fill the necessary parts under ESP8266.ino

#define WIFI_SSID "<ENTER WIFI SSID HERE>"
#define WIFI_PASSWORD "<ENTER WIFI PASSWORD HERE>"

const char* SCOPE_ID = "<ENTER SCOPE ID HERE>";
const char* DEVICE_ID = "<ENTER DEVICE ID HERE>";
const char* DEVICE_KEY = "<ENTER DEVICE primary/secondary KEY HERE>";

Compile it! and deploy to your device. (see below)

• Download Arduino-CLI from this link
• FOR WINDOWS, use version 0.3.3 => download
• FOR WINDOWS, you will need a driver for USB to UART
• Add additional url to board manager in arduino-cli.yml (this is usually located in the same folder of CLI executable)

board_manager:
  additional_urls:
  - http://arduino.esp8266.com/stable/package_esp8266com_index.json

Setup the environment; (under the project folder)

arduino-cli-0.3.... core update-index
arduino-cli-0.3.... core install esp8266:esp8266
arduino-cli-0.3.... board attach esp8266:esp8266:nodemcu

Compile!

arduino-cli-0.3.... compile

Upload

arduino-cli-0.3.... upload -p <PORT / DEV?? i.e. => /dev/cu.SLAB_USBtoUART >

Monitoring?

npm install -g nodemcu-tool

Assuming the port/dev for the board is /dev/cu.SLAB_USBtoUART

nodemcu-tool -p /dev/cu.SLAB_USBtoUART -b 9600 terminal
