Hi,

 

 

I am trying to activate GPS on pca10090, VERSION 0.85, using asset tracker example, tag : v1.0.0-rc4

 To be able to use the GPS within asset_tracker, the "real gps" usage was added after the v1.0.0 tag. Could you try running on master to see if this works better?

 

[00:01:03.118,316] <err> nrf9160_gps: Could not enable GPS mode, error: -8

This is related to the AT%XSYSTEMMODE AT command, where it cannot be successfully sent when the modem is already active.

Could you try sending this AT command prior to running the "modem_configure()" function call?

 

Kind regards,

Håkon
