Turn on and off modem

[nWre]

Hi nordic. I want to turn on and off the modem of the nrf9160 when I'm not using it. When I am using it, I am using your FTP library to sent sensor data to my server.

Here is the problem, If I do this for example:

//First inited from prj conf so it starts connected
lte_lc_offline(); 
lte_lc_init_and_connect();
//This is fine so far, it can go offline and online once.

//Here is where it doesnt work anymore
lte_lc_offline(); 
lte_lc_init_and_connect();

On the last lte_lc_init_and_connect(); I get this:

E: Could not send AT command, error: 65536

which is an error code I havent found anywhere, it is, however, a power of 2, which is strange. 2^16 to be precise.

My question is: How do I turn on and off my modem for when I need to use it?

Kindest regards and gratitude

Hello,

you're not supposed to initialize the modem more than once. So instead of calling lte_lc_init_and_connect() twice, you should just call lte_lc_connect() the second time since the modem is already initialized.

Hi! You are correct. I tried this and it worked fine. I still have some data transmission problems but I started another thread for this. Thank you Hakon, you the man.
