Linde Bluetooth USB Stick User Guide Revision History Version Date 1.0 20.08.2018 Notes

(IR) Initial Release Introduction Author Pascal Hnisch 1. Introduction This document describes the first steps to bring your Linde Bluetooth USB into operation. Please feel free to contact us under support@m2mgermany.de if you need any further information. 1.1. Functional Principle The Linde Bluetooth USB Stick is recognized as a standard USB serial device by your operating system. Microsoft Windows will add a new COM port and Linux-based systems will show the device as /dev/ttyUSB*. Thanks to the integrated Bluegiga iWRAP firmware you do not depend on the Bluetooth stack of your OS. Instead you can communicate to your Bluetooth devices directly over this virtual serial port.
