I tried connecting the UART1 and UART2 connection to the secondary port of the Pixhwak 2.1 Black Cube, but I’m not seeing any messages that it was detected. The DroTek F9P OEM is recognized as a secondary GPS. Are the UART connections (RX,TX lines) compatible with the Pixhawk 2.1 secondary GPS connection? I manually configured the u-blox messages required since it wasn’t being configured or auto-configured: NAV-POS-LLH, NAV-STATUS, NAV-SOL, NAV-VELNED, but that didn’t help detection either. I’m using ArduCopter 3.6.11.
Is there anything I should have to do to get the Pixhawk 2.1 to recognize the Sirius RTK? Do the RX and TX lines need to be reversed for the Pixhawk 2.1?
I did connect with u-center and the GPS was acquiring fixes BTW.
