TapNLink Primer NFC-BLE

The TapNLink Primer enables the connection of your STM32-based electronic system to a smartphone via the Bluetooth Low Energy (BLE) interface (range: 10 m) and/or Near Field Communication (NFC) interface (range: 3 cm). Using the smartphone as a gateway, the Primer transfers application variables to a dedicated, provisioned, pre-configured IoT Cloud environment where you can view the evolution of variables, record and analyze this data and export it. With TapNLink Primer, it takes just minutes to create your first IoT proof-of-concept.

The Primer connects to your host application via 2 of the microcontroller's GPIO using either the SWD (debug) protocol or the proprietary S3P protocol. 

In just minutes, configure the Primer with variables to be monitored and their access parameters (passwords, read and/or write access, data logging, etc.). Based on this configuration, our IoTize Studio software configures the Primer and provides a sample smartphone app that serves as a local user interface for viewing and/or modifying variables and as a gateway for data transfers to the Cloud.

Physical Characteristics

The TapNLink Primer (dimensions: 35mm x 25 mm x 6 mm) can be easily integrated into your hardware design. It can also be deported to a distance of up to one meter from the target microcontroller.

Security Features

TapNLink Primer supports local security measures at the module level including definition of user profiles (login/password, access rights to specific variables) and encryption of communication channels.

Smartphone Application Support

Smartphone applications are based on the IoTize Communication Service app for Android (v4.0.3 or later versions) and iOS (v10) smartphones. This app manages the local wireless interfaces (NFC, BLE, Wi-Fi) on the smartphone.

Applications can be developed as native apps or HTML5/CSS hybrid apps.
