Hello,

You have looked at this documentation.

https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/sip_pin_configuration/xcoex0.html?cp=2_1_5_0

COXEXO is used only for GPS , not for other bands or LTE.

Thanks.

We need XCOEX0 Pin active just in case we use GPS (not LTE).
What configurations should be set to use GPS ?

Hello,

Could you please explain what have you meant by this line ''.... should we you just next configuration?''

Kazi Afroza Sultana,
My question:
First, we used LNA just for GPS. LNA enable is connected to COEX0 should we you just next configuration?
AT%XCOEX0=1,1,1570,1580
In addition how the nRF MCU knows the current frequences range when we sending the data over LTE? It's manage internally inside the MCU or we need to apply additional configuration and set LTE & GPS frequences and then according to the type of the LTE or GPS activation MCU choose state of COEX0 PIN.

Hello,

What is your pin numbers for both of these antenna ports (LTE and GPS)? Here you can find the pin assignment https://infocenter.nordicsemi.com/topic/ps_nrf9160/pin.html?cp=2_0_0_9_0 . You should know what kind of control you need for the hardware. You can send us the schematic of your schematic board.

AT command output shows that you got good range for GPS ( 1570 -1580) since GPS is universal.

Here is the different LTE band LTE frequency bands - Wikipedia.

Thanks.
