Using GPS active antenna

[ERAN GISSER]

Hi ,

I would like to use an external GPS active antenna on the nRF9151 EVB for testing (J2), does it disconnect the on board antenna GPS ? should I connect/disconnect any solder bridge ?

How does it works ? priority ?

Tnx,

Eran.

Hi,

External GNSS antenna can be connected on J2 on nrf9151-dk. When using an external GNSS antenna, the onboard GNSS LNA (U2) must be disabled to avoid interference. This is done by ensuring that the VEN signal is low and set using AT%XCOEX0. You can find relevant information in the documentation - antenna interfaces and GNSS. 

Best regards,
Dejan
