[quote user=""]1、Becuse of customer's PC administrator has been implanted managed software in the engineer's computer，So the managed software may limit some processes in the computer，the engineer want to know which processes will run if the command of west built is executed.[/quote]

West is a meta tool based on Python. Have a look at the West repository. Note that the Toolchain Manager found in nRF Connect for Desktop is designed to be a sandbox solution, and should be helpful in administrator controlled environments.

[quote user=""]2、I find that the document of ncs have APIs of nrf cloud only,Can these APIs use on customer's could?[/quote]

The nRF9160: Cloud Client sample might be a good starting point, as this uses the Cloud API which allows the use of different cloud backends. What cloud solution does the customer use?

[quote user=""]3、Is there any APIs support when the nRF9160's fota is through the customer's could?[/quote]

Yes, the FOTA download library should provide the correct API.

[quote user=""]4、Where to get the A-GPS data to could If the customer use their own could instead of nrf cloud?[/quote]

Have a look at the SUPL library. This library can be used to receive A-GPS data from a SUPL server using the SUPL protocol

[quote user=""]5、Because of there is no base stations of Cat-M in China，How does customer develop SMS of Cat-M?Is there any tool for customer develop Cat-M application?[/quote]

If there is no LTE-m support in China, then there isn't much we can do. You will need to contact the local service providers. GSMA Deployment Map provides more information on local NB-IoT providers

[quote user=""]6、Is there any APIs to get the modem or gps power off completely when the MCU uint is running?[/quote]

The CFUN - Functional Mode AT command controls the nRF9160 modem function. It can configure the functional mode to Minimum (Power off), Normal, or Offline mode (Flight mode).

[quote user=""]7、Dose example in the v1.7.0\zephyr\subsys\settings support nrf9160?[/quote]

It does not state that this is supported in the Settings example documentation, the only way is to test.

Hope this answers your questions.

Kind regards,
