Hi,
Programming nrf/samples/nrf9160/gnss sample code (nRF Connect SDK V2.0.0) in PCA10090 development version (0.8.2).
Add the definition of "CONFIG_MODEM_ANTENNA_GNSS_EXTERNAL=n" to prj.conf (switch to non-external antenna).
However, it is confirmed that the measuring point "measure point" of the hardware is in a high level state.
Could you tell me the correct method of external/internal antenna switching through FW setting?
Any help would be appreciated.
Best regards,
Lulu.C
Hi Amanda,
It means that there is no difference between the settings of CONFIG_MODEM_ANTENNA_GNSS_ONBOARD=y and CONFIG_MODEM_ANTENNA_GNSS_ONBOARD=n in the PCA10090 development version (0.8.2)?
So, confirm that the R6 and C10 contacts on the development version are kept high?
J6 in PCA10090 development version (0.8.2) is not suitable for external physical antenna with coaxial plug?
Regards,
Hi Amanda,
Thank you for your reply.
It is currently confirmed that the new version of nRF9160-DK (V1.1.0) circuit design integrates GPS_ EN control is connected to the GPIO pin of COEXO.
However, the GPS products that our company has mass produced are designed according to the old nRF9160-DK circuit to confirm GPS_ EN control is connected to the GPIO pin of MAGPIO.
When GPS_ EN control is connected to the GPIO pin of MAGPIO. The parameter definition "CONFIG_MODEM_ANTENNA_AT_MAGPIO=" AT% XMAGPIO=1,0,0,1,115741577 "in its .config seems to be invalid for GPS_EN control.
For the problem that GPS_EN has no effective control. I need your professional help, thank you.
