What should be MAGPIO command sequence for connecting to NBIOT network ?

[Jagir008]

In my application i need to use NBIOT network & GNSS.

For that i found that i need to configure AT%XSYSTEMMODE=0,1,1,2.

But i am not clear on what should be configuration for AT%XMAGPIO command ?

Hi Jagir008,

Yes, that would be the correct use of the XSYSTEMMODE AT-Command.

However, you can achieve the same functionality if you use the LTE Link Control driver and enable the config:

CONFIG_LTE_NETWORK_MODE_NBIOT_GPS in prj.conf.

It's quite easy the process of connecting to a network when you enable the LTE Link Control driver (instead of manually adding the AT commands yourself)

You should not need to change anything with the XMAGPIO command. 

You would usually use it when e.g. to control an external antenna tuner, or any other GPIO-controlled device, whose state depends on modem's RF frequency.

In that case, I would recommend this White paper: nRF9160 Antenna and RF Interface Guidelines

Hi Martin,

What should be initialization steps for using LTE Link control Driver.

Currently i have used "lte_lc_init_and_connect()"  & added configuration in pr.cfg file.

As per my understanding i need to include kConfig file for LTE link control & Call this function for initialization.

Please let me know required steps for it.
