We’re trying to get our indoor navigation system to work (Marvelmind) that uses an external GPS to spoof the signal and in the manual it says to use -B /dev/ttyAMA0 for UART or /dev/ttyUSB0 for virtual UART via USB. We’ve been trying to use these but I noticed that /dev folder does not even have these options.
Hello George: I have the same problem today while trying to install the apm-navio2. Hence checked the forum to find your response. The Docs page mentions doing this step. Hence tried it. Where do I find the Release Notes? Unless I have to build the binaries from the sources. Could you please let me know? Thanks in advance.
Also update to the opening post: Seems that the USB option is still ttyACM0 (not ttyUSB0) and the UART option ttyAMA0 is now visible. No problem with that but the old manual did not apply at least in our case.
We are using the current Jesse Image from the NAVIO Website and were trying to use the Marvelmind indoor GPS.
We tried to use the indoor GPS both with the -E flag and the -B flag, we also tried both the USB and the UART connection. In each trial we also adjusted the Baudrate for the respective Serial port in QGC.
Everytime we plug in the indoor GPS the ardupilot crashes and cannot be restarted, however it appears as running. The LED on top of the navio blinks green. Both Mavros crashes, and QGC becomes unavailble.
Do you have any idea what we are doing wrong?
We set the configuration on the Beacon’s as instructed by Marvelmind (e.g. Baudrate 115200, and Protocol NME with all the messages enabled)
