nRF9160 (NB-IoT) nRF cloud connect error :(-111)

[Nikunj]

Hello community,

I successfully flashed assets_tracker  code into board and configure in NB-IoT using Configure NRF SDK project in segger studio.

I used Vodafone SIM card and NB-IoT is fully developed in Ireland. 

When I start nRF9160 dk it connects with Vodafone Ireland and registered to the network in roaming mode.

I do also have data in SIM card and code successfully came out from function modem_configure().

In cloud_connect(NULL) function it returns with an error

nRF cloud connect error: -111

Now, How am I suppose to connect with nRF Cloud?

Thanks in advance.

Regards,

Nikunj Panchani

Hi Nikunj,

The error -111 means "connection refused". 

Could you please flash the AT Client example into your board first, open up the Link Monitor application in nRF Connect for Desktop & see if you can attach to the base station first (see this video)?

Then, could you copy & paste the log file into your comment.

If you still cannot attach to the base station, it may be useful to update to the latest modem FW found here.

Hello Kvaale,

Thanks for reply.

I upgraded modern firmware into modem and uploaded at_client. here are logs from LTE_LINK_MONITOR.

I think it is connected with base station but it is not with nRFcloud.

You can easily see if you are connected to the base station in the Link Monitor tool by seeing if the LTE bar in the top right corner is green (see this video). From the AT+CEREG command at the bottom of your log you received: +CEREG: 5,"2332","02610421",9\x0D\x0A\x00 & the 5 indicates that you are registered & roaming.

The -111 error normally means there is something wrong with your SIM card, either that you have not registered it or there is no data left on it. However, since you mentioned nB-IoT & Vodafone, I believe the issue may be related setting the APN (access point name). 

In the AT client example, could you try running: 

AT+CGDCONT=0,"IP","nb.inetd.gdsp"

Then, switch over to the asset tracker example again. Hopefully you will be able to connect to the cloud then. I have also heard of one customer having to talk to Vodafone directly in order to get their SIM card activated.

Hello Kvaale,

Thanks for reply!!!

According to nRF AT Command document we do not able to change AT+CGDCONT=0.

I already registered SIM card and got APN automatically,

 +CGDCONT: 0,"IP","ep.inetd.gdsp","10.21.113.47",0,0

"if you are connected to the base station in the Link Monitor tool by seeing if the LTE bar in the top right corner is green" LTE is already green, SIM registered with Vodafone Ireland.

After debugging I came on a point that,

It throws an error from connect(client->transport.tcp.sock,client->broker,peer_addr_size) after closing socket it throws error 60 which is "Connection Timeout".

Also for this  +CGDCONT: 0,"IP","nb.inetd.gdsp","10.21.113.47",0,0 I tried with <stat> 1  but this APN is not giving any IP when I am trying AT+CGACT=1,1 

I also tried with simple MQTT example by changing HOSTNAME and PORT of my MQTT server created by node-js but results are same to me.

Nikunj

Hello Community,

Thanks for support.

Local service provider gives limited ip address to connect from NB-IoT SIM card. So we have to direct contact local service provider and we have to provide on which ip addresses we will work.
