What's the difference nrf_cloud_agps and AGPS using google SUPL data?

I'm not clear about this. README.rst doesn't explain about it.

Also, to use the nrf_cloud_agps, do you have to use iBasis SIM?

Hi

The data that is used in the nrf_cloud_agps and AGPS using Google SUPL data should be the same, but the vendor of the data and the protocols are different. 

You will not be locked to using an iBasis SIM with the nrf_cloud_agps example. Please take a look at the A-GPS documentation page for more details on this.

Best regards,

Simon

May I have a question?

I would like to use AGPS + LTE + eDRX. There are some programs using AGPS

asset_tracker, gps, nrf_cloud_agps.

which one should I refer to in making a own project?

gps program has smaller amount of code but I'm not sure AGPS + LTE is available by adding 

CONFIG_LTE_NETWORK_MODE_LTE_M_GPS=y

asset_tracker and  nrf_cloud_agps use nrf_cloud.h library and require a lot of code writing. I'm developing a program based on aws_fota which uses a common mqtt library instead of nrf_cloud library. If I integrated the aws_fota and nrf_cloud_agps, there will be a large amount of code.

What do you think of this?

[Yusuke]

I read "gps" sample program. As long as I understand, it's turn of/off LTE so I think it's not possible to make eDRX + AGPS program using it. Then to achieve it, you need to make a program referring o nrf_cloud_agps program.

Is this understanding correct?
