Unable to Connect to the Cloud

SteveD0

I can use the LTE Link Monitor to select my device and run the AT commands. I have a signal strength now of 4 bars. I’ve been typing in AT+CGSN to get the IMEI number. Is that correct?

When I go to the Connect to the Cloud I get the message: There was an error adding your device: No device found for this id. The device has not yet been provisioned. Troubleshoot nRF Code 40412

I’m entering the 15 digit IMEI number (from above) after feather- to add the device id and the cloud key you provided as the PIN. I’ve even tried the cloud key from both of my “Get Started” cards.

I get the same result each time. Not sure where to go from here? I even went back and recompiled the nrf AGPS Sample again.

Correct.

Your device needs to connect to nRF Connect Cloud before you attempt to add it. When it does connect you can then add it to your account.

SteveD0 Are there certificates I need? Do I need to do anything with firmware?

The certs are pre-loaded by me at the factory. 😀

SteveD0 I’ve placed the SIM card in the board. Would I need to activate it first before connecting to the cloud?

Correct.

I don’t know if it means anything but in the Link Monitor the UART and LTE statuses are red.

SteveD0

SteveD0

I’ve activated the SIM card and the Hologram status is “Your device is activated and ready for use on our network. We have not yet seen it connect to a local tower or pass data.”
When I look at the device information there is no IMEI info showing. All that shows is the SIM number, link id and device id.

I’m still not able to add an LTE device on the nRF Cloud when I enter the IMEI and cloud key.

The nRF Connect Desktop is show in only 1-2 bars. What I thought was 4 bars earlier was 4 blank bars before I activated the SIM card.
I’m seeing several AT&T and Sprint networks available on the nRF Connect Desktop.
I may have made a mistake on the Hologram site when I regenerated an API key. Could that be an issue?
I’m still seeing the LTE status fade in and out with both red and yellow.

Any suggestions of what to look at or do?

SteveD0 what does the output of your device look like? It should look something like this.

*** Booting Zephyr OS build v2.3.0-rc1-ncs1-2410-g7d20f2ebf259  ***
D: COEX0 set: AT%XCOEX0=1,1,1565,1586
I: A-GPS sample has started
I: Connecting to LTE network. This may take minutes.
I: PSM mode requested

Once a connection is established you should see something like:

+CEREG: 2,"5003","00C0CD05",7,0,0,"11100000","11100000"
+CSCON: 1
+CEREG: 5,"5003","00C0CD05",7,,,"11100000","11100000"
I: Connected to LTE network
D: GPS socket created, fd: 1232491587
I: CLOUD_EVT_CONNECTING
I: CLOUD_EVT_CONNECTED
I: CLOUD_EVT_PAIR_DONE

After that it should start doing its thing. I just had an issue with my device where it showed CLOUD_EVT_CONNECTED and then CLOUD_EVT_DISCONNECTED without an error. I removed it from my nRF Cloud console an re-added it and that seemed to fix the issue.

Make sure, most importantly, it shows A-GPS sample has started

Here is what I just got:

*** Booting Zephyr OS build v2.3.0-rc1-ncs1-2410-g7d20f2ebf259 ***
D: COEX0 set: AT%XCOEX0=1,1,1565,1586
I: A-GPS sample has started
I: Connecting to LTE network. This may take minutes.
I: PSM mode requested
+CEREG: 0,“FFFE”,“FFFFFFFF”,7,0,0,“11100000”,“11100000”
I: Network connection attempt timed out
I: Using fallback network mode

I’m going to reboot and start everything and see what happens.

SteveD0

Right now I have 0 bars. I’m going to let it sit. When I restarted I didn’t see the various networks available either.

Might this mean I need to get a signal booster?

SteveD0

I now see the networks again, but I still have no bars.

jaredwolff

SteveD0 I’m not sure about that. 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

jaredwolff

SteveD0 Also, what is the output of AT%XSYSTEMMODE?

@SteveD0 can you address these questions?

jaredwolff

Bear in mind you shouldn’t be using the AT+CFUN=1 button for the AGPS example. It will automatically connect.

SteveD0

I just switched to my other device and here is what I got:
*** Booting Zephyr OS build v2.3.0-rc1-ncs1-2410-g7d20f2ebf259 ***
D: COEX0 set: AT%XCOEX0=1,1,1565,1586
I: A-GPS sample has started

+CEREG: 2,“0415”,“00F7710F”,7,0,0,“11100000”,“11100000”
+CSCON: 1
+CEREG: 5,“0415”,“00F7710F”,7,,,“00001000”,“00011111”
I: Connected to LTE network
D: GPS socket created, fd: 1232491587
I: CLOUD_EVT_CONNECTING
I: CLOUD_EVT_DISCONNECTED
+CSCON: 0
+CEREG: 5,“0415”,“00F83910”,7,,,“00001000”,“00011111”
+CSCON: 1
+CEREG: 5,“0415”,“00F7710F”,7,,,“00001000”,“00011111”
+CSCON: 0

I then went into nRF Cloud and was able to add the device. It however is saying that it is disconnected.
I still have 0 bars on the desktop.
I just entered AT%XSYSTEMMODE? on the desktop for the second device and nothing happened.

I can go back to my 1st device and retry and enter this AT command as well, since that is the original device having issues.

SteveD0

I still have the second device connected . I closed it down and restarted it and before I reset the device I executed the AT command. Here is the response from the AT command:
AT%XSYSTEMMODE?
%XSYSTEMMODE: 1,0,1,0
OK

I’m going to switch devices and try the command again…

SteveD0

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?

SteveD0

Is the AT+CFUN=1 the reset button?

SteveD0

Now I’m getting:

AT%XSYSTEMMODE?
%XSYSTEMMODE: 0,1,1,0

jaredwolff

SteveD0 The output should be 1,0,1,0

If you can run

 AT+CFUN=4
 AT%XSYSTEMMODE=1,0,1,0
 AT+CFUN=0
