I went back to the 1st device and put the SIM card back in it. The AT command output is the same and it stops in the same place as it originally did so it is not connecting to the LTE network.
Thoughts?
Unable to Connect to the Cloud
Is the AT+CFUN=1 the reset button?
Now I’m getting:
AT%XSYSTEMMODE?
%XSYSTEMMODE: 0,1,1,0
jaredwolff Do you have the LTE antenna connected properly? It should be the connector underneath the RST button.
The “bars” only work when the device is reporting status in the terminal. I wouldn’t use that as an indicator whether or not you have service.
Additionally, is your SIM activated? It should have a green dot and “Ready” next to it in the Hologram dashboard.
Do you know if you get any AT&T, Sprint or T-Mobile service at your place? It could very well be that you’re out of service area. A great way to check is by running the at_client example and using Automatic requests and pressing the AT+CFUN=1 button
@SteveD0 can you address these questions?

I ran the suggested AT commands on each device.

TEST 1 - FAILED on DEVICE w/ SerNr ending in 504:
Here is what I got:
AT+CFUN=4 AT%XSYSTEMMODE=1,0,1,0 AT+CFUN=0

OK
And did nothing when I pressed RESET - if I had waited long enough it would have timed out

LOOKS LIKE THIS IS WORKING…
QUESTION??
Should I activate my second SIM card and use it in the device w/ SerNr ending in 504 and retry this whole process?
ALSO, ANSWERS TO OTHER QUESTIONS
1) Yes I connected the LTE antenna correctly
2) The device (152) is working correctly on network AT&T Mobility

It’s likely a settings issue on the first device. Bear in mind that the commands need to be on separate lines
AT+CFUN=4
AT%XSYSTEMMODE=1,0,1,0
AT+CFUN=0Then reset. Then make sure the settings have taken with
AT%XSYSTEMMODE?The reply should be
%XSYSTEMMODE: 1,0,1,0You only have to do this once.
I recommend you load the at_client sample on the one that is not working and re-attempt connecting with that firmware. This helps rule out weird configuration issues.
Also, are you using a firmware you built or the one that I pre-built?
If you mean by firmware executing the newtmgr image upload when the device was in DFU mode I loaded the firmware I built as I followed the steps from the nRF Cloud AGPS Sample. I’m not actually sure how to load your pre-build firmware nor where to find it?
@SteveD0
The at_client example is here: https://docs.jaredwolff.com/nrf9160-at-client-sample.html
The nrf_cloud_agps page is here https://docs.jaredwolff.com/nrf9160-agps-sample.html
Both have respective links to their downloads. They can also be found on the downloads page
The download links were not obvious before. They’re now very obvious.
I’m trying to use the Desktop Programmer to update the modem firmware. I can select the device okay, however, the picture doesn’t look like the instructions. There is no hex file in the memory of the device.
I also can browse and get the merged.hex file and place it into the file memory layout but the menu items to erase and/or write are all grayed out.
The log shows this:

I then went back and loaded blinky. Upon returning to the programmer same thing there was no visible files in the memory.
After I didn’t see the blinky in memory on that device, I went to my other device and tried to look into the memory and didn’t see anything there.
I don’t have the programmer board yet if that is what is needed. It should arrive soon.
SteveD0 I don’t have the programmer board yet if that is what is needed. It should arrive soon.
You need the programmer and cable for the programmer app to work. I recommend you don’t update your modem firmware until you can get your setup working first.
okay.
So most definitely the firmware needs to be updated. After activating a new SIM card for this device and getting it set up on nRF Connect for Cloud the message is, “Upgrade your firmware to view Network, Sim, Device, and Service Information”
SteveD0 this is referring to the Asset Tracker application firmware. You can ignore that message. The nRF9160 Feather currently does not support the Asset Tracker application.
