GPS_TYPE2: 9 GPS_AUTO_SWITCH: 2 CAN_D1_PROTOCOL: 1 CAN_D2_PROTOCOL: 1. Switches of both modules are set on CAN mode but it is the same. Both of them show the blue breath light and the mission planner does not detect neither of them now. Also, in GPS_AUTO_CONFIG I have tried all configurations 0,1,2 but neither of them works, the gps are not

After successfully calibrating the compass on mission planner, I have the following message: GPS: no fix. Could someone help me please? I don’t know what to do. louistwiice (steve) August 5, 2019, 3:34pm 2. Finaly, I solved the problem. I just had to put it outdoor a moment. It seems the GPS doesn’t work inside a house. Hi I have a pixhawk Point-and-click waypoint entry, using Google Maps. Select mission commands from drop-down menus. Download mission log files and analyze them. Configure APM settings for your airframe. Interface with a PC flight. simulator to create a full hardware-in-the-loop UAV simulator. See the output from APM’s serial terminal. In this section of the manual, we will cover the basic setup of the units. To setup the RTK units with Ardupilot, you will need Mission Planner installed on your computer or Ground Control Station and Ardupilot installed on your flight controller. If you are using PX4 firmware and QGroundControl ground station software, please refer to the link
An RTCM corrections stream is available to Mission Planner on the computer (Base Station or NTRIP) Pixhawk 4 and the AsteRx receiver have been set up and are communicating. To receive corrections from a base station, go to Initial Setup > RTK/GPS Inject and select the option to receive corrections. It is possible to receive corrections via COM

After completion, click on the CONNECT on top right corner of the window to connect the APM board to PC. Now it will show the Device as "Quadrotor". Step 2 - Calibrating Compass and Accelerometer. Now again go to the Initial Setup tab and click on Mandatory Hardware.

So here's the issue: My APM2.0 always has the 3DFix light go solid within a couple minutes, but quite frequently Mission Planner will display "No GPS" (and of course hdop:0 and sats:0) when connected via 3DR radios. I can get the GPS to register by disconnecting Mission Planner, pressing the reset button on the APM2, and then reconnecting Mission Planner. The GPS will keep its 3D Fix during Logical Serial Port to Physical UART Assignment. ArduPilot Serialx Port numbering is logical, rather than physical. Which UART or USART port is assigned to a Serial Port is determined by the autopilot’s hardware definition file. Serial Port 0 is always assigned to the USB port, but others can vary. Check its description page.
The bad thing is, that it also loses the GPS signal in Mission Planner. I took a look at the "Full Parameter List" in Mission Planner and saw, that I can change the GPS protocol to NMEA. As this gave me stable and good signals in u-center, I configured the M8N again in u-center to the out protocol NMEA with a baudrate of 38400 at 5Hz
