The ST BLE Sensor application is used in conjunction with an ST development board and firmware compatible with the BlueST protocol to give you access to all the sensor data, which you can log to different cloud providers, and to update the board firmware directly from a mobile device via the Bluetooth® Low Energy protocol. After discovery ST development board, the app shows you a list of available demos and you can navigate through them to discover the functionalities of your board. Demos can be related about environmental, cloud, audio, board configuration, machine learning and and many other functionalities. The application is built on top of the BlueST SDK library implementing the BlueST protocol and helps you export the data easily via Bluetooth® Low Energy. The application also supports firmware library algorithms like motion-sensor data fusion, activity recognition and pedometer functionality. Both SDK and application source code are freely available at: https://github.com/STMicroelectronics
Magic Smoke
Establish custom TCP connections to send specific commands. Save up to ten commands for quick access, or type any message directly. This utility is ideal for testing network connections and embedded systems.
- Custom TCP connection setup
- Save up to ten custom commands
- Send any typed message
- Appends carriage return and linefeed
- Supports IP address and port input

This app allows you to send custom commands via a TCP connection. You input the IP address and port number for the TCP connection you would like to create, and then you can customize the ten buttons to have ten saved commands. The “Any Command” text field can send any message that is typed into the text field. A carriage return and linefeed are appended to all messages. It was originally developed for the NCSU Embedded Systems course ECE 306, but it works for any TCP connection you would like to create!
