TapNLink Primer for STM32 instant mobile connectivity and HMI. TapNLink Primer Offers STM32 Instant Connection to Mobiles

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