Device BME680 Service

About

The EdgeX Device BME680 Service is developed to communicate to BME680 sensor connected to the I2C bus in an EdgeX deployment

Supported Boards:

• NXP ls1012a frwy - ARM64 bit
• Raspberry Pi 3B(+) - ARM64 bit

Dependencies:

The Device BME680 service based on device-grove-c is developed using BME680_driver library. The repository can be found on git at BME680_driver.

Build Instruction:

1. Check out device-bme680-c available at device-bme680-c

2. Build/install device-c-sdk library and headers by using the following command

sh> ./scripts/build_deps.sh

3. Build the device service

sh> ./scripts/build.sh

By default, the configuration and profile file used by the service are available in 'res' folder.

Configuration

1. Port number specified in the configuration.toml
2. /dev/i2c-0 is hardcoded in src/c/main.c file since in NXP board it is i2c-0. For Raspberry PI, it might be i2c-1.

Note:

1. Make sure that i2c_dev module is loaded and /dev/i2c-X file is present
2. On Raspberry PI, make sure that i2c_arm=on is set. This enables i2c-1 device, required for communication between Grove PI & Raspberry PI boards.
