Page 18: Troubleshooting
EVK-F9T - User guide Troubleshooting My application (e.g. u-center) does not receive anything Check whether the blue LED on the evaluation unit is blinking. Also make sure that the USB cable is properly connected to the evaluation unit and the PC. By default, the evaluation unit outputs NMEA protocol on Serial Port 1, or on the USB. - Page 19 (e.g. disabling the main communication port). The EVK-F9T does not work properly when connected with a GNSS simulator When using an EVK together with a GNSS simulator, pay attention to proper handling of the EVK. A GNSS receiver is designed for real-life use, i.e.

Page 20: Common Evaluation Pitfalls
EVK-F9T - User guide 10 Common evaluation pitfalls • A parameter may have the same name but a different definition. GNSS receivers may have a similar size, price and power consumption, but can still have different functionalities (e.g. no support for passive antennas, different temperature range). Also, the definitions of hot, warm, and cold start times may differ between suppliers. -
