The TapNLink NFC, Wi-Fi, BLE module (root part number: TnL-FIW103) offers instant
integration of contactless/wireless radio interfaces to enable the connection of a microcontroller-
based target system to a local mobile device (smartphone, PDA, tablet, PC, etc.).
TapNLink connects directly to two GPIOs on the microcontroller in the target system. These
GPIOs can be either the target microcontroller’s debugging/programming port (ex. SWD) or any
pair of GPIOs enabled by the IoTize S3P protocol (application relinking is required). The
connection to the target microcontroller is non-intrusive and allows read and/or write access to
variables in the target microcontroller’s memory. The data addresses and access parameters
for the target system are configured in the TapNLink using the IoTize Studio configuration
environment.
TapNLink communicates with local mobile devices via their NFC and/or Wi-Fi or BLE interfaces.
The Tap Manager app (Android or iOS) on the mobile device manages its communication
interfaces, thus eliminating the need for the target-system designers to code or validate these
mechanisms. Designers instead focus on creating the user interface for the target system.
With TapNLink NFC, Wi-Fi, BLE modules, a local mobile device can serve as a network
gateway to bring data to or retrieve data from the Cloud. Data that is read by the TapNLink can
be transmitted via the mobile device’s data or network connection when available. For this,
IoTize provides an MQTT-based relay with IoT Cloud platform translators. This MQTT
infrastructure is open source software that designers can install on servers and adapt to any
private or public IoT Cloud platform.
