Hi,
We are using nRF9160 on our custom board. (SDK 1.9.1) with "serial lte modem" firmware.
We have two external antennas for GPS and LTE.
Now we are implementing location receipt via A GPS, GPS, CELLPOS and we ran into a misunderstanding of how COEX0 should be configured.
Based on the description of the configurations for %XCOEX0, I see that there are frequency bands for both GPS and LTE:
The following command example sets COEX0 to 1 when GPS is enabled (and 0 when GPS is turned off). COEX0 is not used with other frequencies (or LTE): AT%XCOEX0=1,1,1570,1580 OK The following command example sets COEX0 to 1 when GPS is enabled, or LTE frequency is 600–800 MHz or 2000–2180 MHz: AT%XCOEX0=3,1,1570,1580,1,2000,2180,1,600,800 OK
In all examples from GNSS_AT_commands.rst AT%XCOEX0=1,1,1565,1586.
Actually the question is what ranges and specifically for what it is necessary to specify (GPS, LTE)?
Our device should work correctly "around the world", but for the same LTE each country has its own frequency range.
For example, our communication providers have allocated a frequency from 1800-2600 (for LTE).
