The frogLink is our SDK (Software Development Kit). With its USB interface, it connects the frogblue Bluetooth® network at high speed to the PC or acts as a gateway to other systems, such as MOBOTIX™ cameras or higher-level building controls. Communication takes place in plain text with the names used in the frogblue project. Access can be restricted via filter functions.

Further functions for querying messages and room topology, which are provided by frogLink, are available. This makes it easy to implement customer-specific user interfaces for PCs or tablets. The frogLink is also used to establish a connection to voice assistants such as Alexa, etc.

The frogLink offers two different operating modes:
* frogblue mode: Using frogLink as Bluetooth® communication interface for configuration and operation with a Windows computer
* Text mode: Use as a serial text gateway (ASCII or JSON) for the frogblue integration of and into other systems.
