Data Corridor

This repo contains the firmware for gateway node. Data corridor is reponsible for forwarding messages from gateway to individual nodes.

There are two firmwares that you need to flash into your devices to make the gateway work properly.

1. Gateway Node Firmware
2. Data Corridor Firmware (this)

Getting Started

Setup

• Clone the project
• Open the project in VS Code (with Platform IO extension installed)
• To run the projcet select esp01_1m environment
• Some other steps go here
• Build and upload the code to ESP01s device

Hardware Connection

1. Connect ESP32's TX2 to RX pin of ESP01.
2. Connect ESP32's RX2 to TX pin of ESP01.
3. Connect ESP32's 3v3 pin to 3v3 pin of ESP01.
4. Connect ESP32's GND pin to GND pin of ESP01.
5. Connect ESP01's CH_PD to 3V3 to enable the chip. Otherwise the chip won't start.

Setup Debug Serial

If you wish to see the debug messages from data corridor. Connect an FTDI adapter to it. Pins connections:

1. Connect Tx from FTDI to GPIO 0 of ESP01s
2. Connect Rx from FTDI to GPIO 2 of ESP01s
3. Connect GND from FTDI to GND on ESP32/ESP01s board

Working

Hardware serial interface is used to communicate with ESP32. Another software serial interface is created on pins 0 and 2 for putting out debug information. Gateway forwards every command to ESP01 through UART and then ESP01 is responsible for sending that command to its respective nodes.
