Can not run GPS example code available in nRF Connect SDKv1.0.0 on nRF9160 DK.

Question

Hello, 
 I am working on nRF9160 DK development platform. 
 For that i Compile & run GPS example, But while debuging that example i find that mcu stucks in CPU Idle function for infinite period of time. 
 And this is happening while creating a socket. 
 I Assume that sample example code should not have any issue it should run flawlessly, i think i am missing soemthing while creating an environment / installing SDK & toolchain. 
 Please let know the solution of this issue.

 XSYSTEMMODE states what your system should enable. 
 For instance; NB1 + GPS, or M1 + GPS, or only GPS/M1/NB1. 
 
 Note that in order to use the GPS in combination with either NB1 or M1, you need to be in power saving mode (PSM) on the network you're attached to. 
 MAGPIO is more about your specific design, for instance if you need to switch in certain antenna tuners for the specific bands (incl. the GPS band). 
 
 You can read more about each of these in the AT command specification:

 If you're using the nRF91-DK, you do need to touch this, as it's already setup for you. 
 
 Jagir008 said: Before using GPS/LTE Do we need to set AT_XSYSTEMMODE & AT_MAGPIO by Power Off modem (AT+CFUN=4) & Again Power On, Is this required to done every time ? 
 With modem v1.0.0 and newer, it is now possible to use the GPS while in PSM mode, ie: without powering the modem off/applying new settings/on again. 
 Here's an simplified example for running LTE M1 + GPS.
