    EVK-M8F-0-00 - User Guide 8 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 at 9600 Bd, or on the USB.
  • Page 18 EVK-M8F-0-00 - User Guide The EVK-M8F does not preserve the configuration in case of reset u-blox M8 GNSS technology uses a slightly different concept than most other GNSS receivers do. Settings are initially stored to volatile memory. In order to save them permanently, sending a second command is required.
