Px4 NMEA input

Hey
I tried sending NMEA messages to my pixhawk but it seems that px4 cant read it.
I have searched the web but couldent find an answer…
Does px4 support NMEA?

Same question. I have verified a valid NMEA stream is being fed to the TELEM_2 port by scoping and decoding the RX line real time. I’ve used serial_test to confirm data is arriving but when I decode it, I get jibberish. All serial configuration settings have been confirmed (B9600 8N1) on the sending unit, and Pixhawk parameters config.

What am I missing?

The same for me, Something must be broken.
It is quite important for NMEA to work. All high accuracy GNSS modules from known surveying manufacturers use NMEA only.

For anyone who finds this in the future, 9600 is not a valid baud rate for the SiK radios. Must use 57,600. Dont ask me why. Also this still doesnt solve the larger issue of incompatibility. Some fields in the GPS 2 readout from nsh populate correctly but most dont. This leaves a GPS not OK status meaning it cant be used
