This Arduino IDE sketch implements a client for interacting with the Navia Core platform. Upon connecting to a specified network (e.g., a Navia Core Access Point), the sketch initially performs HTTP GET and POST requests to the Navia Core REST API. It then subscribes to the Navia Core WebSocket API to obtain and display the current QNH (altimeter setting) value.
Installation instructions:
- Download and install Arduino IDE: https://www.arduino.cc/en/software
Some features of ESP32 are not yet supported in Arduino IDE 2. In that case you can install legacy version 1.8.x.
- Follow instructions on installing ESP32 Board in Arduino IDE 1.8.x: https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/
Or if you selected Arduino IDE 2.0: https://randomnerdtutorials.com/installing-esp32-arduino-ide-2-0/
Compile & Run instructions:
In Arduino IDE 1.8.x:
-
Select:
Tools > Board: "ESP32 Dev Module"

- ADC: Pins labeled with ADC can be used for analog-to-digital conversion. Note that ADC2 pins cannot be used when Wi-Fi is active.
- Touch Sensing: Certain pins support capacitive touch sensing.
- PWM: Pins labeled as PWM capable can be used for pulse-width modulation to control devices like motors or LEDs.
- SPI: The board supports SPI communication using specific pins (HSPI and VSPI).
- Input Only: GPIOs 34, 35, 36, and 39 are input-only pins.
- Power Pins: The board provides 5V, 3.3V, and a dedicated 48V for specialized applications. Be careful not to exceed the voltage tolerances of the ESP32 (3.3V) on its GPIO pins.
- Boot Mode Selection: Some pins (like GPIO0, not exposed on our board's external pins) might have special functions during boot. Refer to the ESP32 datasheet for more details.
The board can be powered via:
- 5V Pin: Supply 5V through the designated 5V pins.
- USB: The board include a micro USB connector. Use to upload your sketch and monitor serial output.
- 48V Pin: For high-voltage applications, use 48V pin with caution.
Important: Always refer to the ESP32 datasheet and the schematic of this development board for the most accurate and up-to-date information before connecting external components or using specific pins.
