Arduino Environment Setup

• Download or clone this repo into a directory on your computer.
• Install Arduino IDE on your computer.
• Launch Arduino IDE.
• Install the ESP Arduno Core Board Support Package by following instructions at https://github.com/espressif/arduino-esp32/blob/master/docs/arduino-ide/boards_manager.md
• In Arduino IDE, from Tools > Manage Libraries... install these libraries:
  • PubSubClient by Nick O'Leary, version 2.7.0 or higher
• For the PubSubClient library, edit Arduino/libraries/PubSubClient/src/PubSubClient.h and change MQTT_MAX_PACKET_SIZE to be 1024 instead of 128.
• Open the application source code file esp32_mediumone_bridge_ble.ino from repository directory.

Configuring Wi-Fi and Medium One Parameters

Set these #defines to your own values:

#define WIFI_SSID      ""
#define WIFI_PASSWORD  ""
#define MQTT_USERNAME  ""
#define MQTT_PASSWORD  ""
#define MQTT_PUB_TOPIC ""

Programming the ESP32 Board

Connect the ESP32 board to your computer using a USB cable, then compile and upload the program to the board.
