NEW! The BlueIO832-Mini and the free BlueIO mobile apps suite constitute the I-SYST BlueIO ecosystem.

This versatile Internet-of-Thing (IoT) framework enables users, from their mobile device such as a smartphone, to remotely communicate with an arbitrary physical device - referred to as a target device in this document (Fig. 1). BlueIO832-Mini and BlueIO mobile apps are considered as a data bridge and a data terminal, respectively. After connecting to the target device via a desired serial interface, BlueIO832-Mini streams the data on that physical interface to the BlueIO mobile app over Bluetooth® 5. BlueIO832-Mini provides four built-in app-configurable features of data communications with a target device:

• Serial interface bridge : (i) Connect BlueIO832-Mini to a serial interface (UART, I2C, or SPI) of a target device. (ii) Pair BlueIO832-Mini with BlueIO mobile app on a mobile device. (iii) Configure the serial interface setting in BlueIO mobile app. (iv) Use BlueIO mobile app to remotely send and receive data on this interface.
• GPIO functions: (i) Use BlueIO mobile app to configure pins of BlueIO832-Mini as GPIO for sending/receiving signal to/from a target device. (ii) Pair BlueIO832-Mini with BlueIO mobile app on a mobile device. (iii) Use BlueIO mobile app to send/receive signals(s) to/from the GPIO pin(s).
• Analog-to-Digital Converter (ADC): (i) Use BlueIO832-Mini to convert (up to 2) analog signals to digital signals. (ii) Pair BlueIO832-Mini with BlueIO mobile app on a mobile device. (iii) Use BlueIO mobile app for monitoring the converted digital signals.
• NFC tag: BlueIO832-Mini can be used as an NFC tag once a Nordic®-compatible NFC antenna is plugged into the NFC connector.

BlueIO832-Mini can be used as an IoT embedded development kit for developing the user’s own firmware by using Nordic® SDK. However, we recommend the user to use our open-source library IOsonata, which is built upon the Nordic® SDK, for faster and easier developing firmware on BlueIO832-Mini and any other Nordic® nRF52x SoC-based embedded system.
