TapNLink WiFi, BLE, NFC

TapNLink module with Wi-Fi, BLE, and NFC (Type5) for local connection of microcontroller-based electronic systems to mobile devices and to the Cloud

apNLink modules provide wireless interfaces for linking electronic systems to mobile devices and to the Cloud. TapNLink connects directly to the target system's microcontroller. It integrates into and is powered by the target system.

All TapNLink products are easily configured to control access by different types of users to data in the target system. TapNLink facilitates rapid creation of Human Machine Interfaces (HMI) that run on Android, iOS and Windows-based mobile devices. HMI apps are easily tailored to different user profiles and can be deployed and updated to keep pace with evolving system and user needs.

TapNLink Wi-Fi modules can also be configured to conect the target system permanently to a wireless network and the Cloud. This enables permanent logging of target system data and alarms.
