Discover the ease adding NFC and Bluetooth Low Energy (BLE) connectivity to your STM32 application without redesigning hardware or recoding firmware. Create Human-Machine Interfaces (HMI) for your application as mobile apps (Android, iOS, Windows10). View data on mobiles, or modify specific variables from your HMI app. You can even log data automatically to a provisioned Cloud platform.

No Coding. Just connect & configure!

Your connected proof-of-concept is just minutes away. TapNLink Primer uses your STM32's SWD port so that you can create a connected version of your application and automatically generate your first mobile apps in minutes.
