Hi, i am using Developer studio 5.3.1 and want to build “Helloworld” in WP7601G. I am using MangOH. I think, I am able to build the app.
Jan 6 01:26:49 | test[11109]/testComponent T=main | testComponent.c \_testComponent\_COMPONENT\_INIT() 5 | Hello, world.
But i am always getting “Jan 6 01:58:16 | modemDaemon[659]/le\_pa T=unknown | pa\_mrc\_qmi.c EventReportHandler() 1255 | Network Registration failed error code 15” error.
Could someone help me with this issue?

You can use AT!GPSFIX to start the gps fix.
You can check the status by at!gpsstatus?
To check the result, you can use at!gpsloc?

Moreover, once i installed the windows driver, it does not show the “Sierra wireless AT command port”, it should be a problem, right?

I don’t see problem to compile textLoc application with Developer studio on WP76 R13 package.
You can use my application here.
