I am currently using the EVB board of LC29HDA and I am able to receive NMEA messages. However, I am not receiving any satellite signals.
I’ve tested in clear sky view and waited for long time.
You can check in the picture the NMEA messaegs I receive and the firmware version of the module
I have the same setup and firmware as you and was able to get a fix. Could you please double-check that your antenna is securely connected? If you have a spare antenna, try swapping it in. Also, make sure to test under open-sky conditions and wait for a few minutes longer.
