nRF9160 - getaddrinfo return 60

[p.durys]

Hello,

I'm trying to run Simple_mqtt code on developement board with nRF9160. Connection to LTE takes in my opinion very long time. On basic AT sample code it's connecting a way faster. Next and main issue is that I can't connect to any mqtt broker. First I didn't change anything in code and at end I have information:

ERROR: getaddrinfo failed 60

ERROR: mqtt_connect -47

I changed mqtt broker for HiveMQ and I have exactly the same error. I'm using the latest software from your side:

Hi.

What SIM card are you using, and have you been able to use it (to send data) with other samples previously (such as the asset_tracker application)?

When getaddrinfo times out (error code 60), that usually indicates that you are not able to send IP data due to the SIM card not being activated or supporting LTE-M/NB-IoT.

As to why it takes so long to connect, it looks like it first tries to search for an LTE-M network, but when not finding one after 10 minutes, it starts to look for an NB-IoT network which it finds in a couple of seconds.

Best regards,

Didrik

Hi,

Thank you for fast answer. 

I'm using T-mobile Poland NB-IoT card. I'm able to connect with this card to MQTT brocker via other module form quectel. I'm sure that the card is correct. I know that the T-mobile prefer using UDP instead of TCP/IP maybe that is the issue. Is this possible to switch searching NB-Iot first than LTE-M?

This is what I have from LTE linnk monitor when I turn off "Automatic request.

From the modem trace, it looks like you are not connecting to a cell that has NB-IoT activated.

Does your Quectel model have 2G or 3G fallback?

Is it able to connect to an NB-IoT network?

Does it connect to the same cell as the nRF9160?

You should be able to answer these questions with the +CEREG AT command.

HI,

From MY Quectel BG95-M2 When I send AT+CEREG? I have below answer:

AT+CEREG?
+CEREG: 4,1,"A96B","2040471",9,,,"00000000","01100000"

And this is from nRF9160:

AT+CEREG?

+CEREG: 5,1,"A96B","02040471",9,,,"11100000","11100000"

Regards

I asked the modem team to help me analyze our modem trace.

According to them, the device is given two DNS servers when attaching to the network. The device queries bot of them, but get no response from either.

Could you try to connect to a hard-coded IP address, instead of doing a DNS lookup to get the IP address?

[p.durys]

I changed Host name for IP address: 5.196.95.208. This is mosquitto server for test. Now the board is connecting, but I can't login to the server.

I don't know why serever refuse me. I have similar issue with Quectel modules. I can open MQQT connection, but I can't login. From PC is no problem to do that. Can you tell me what those errors code means?

[p.durys]

I have also information from T-mobile Poland that Modules has to support ePCO to distribute DNS addresses. Does nRF9160 support ePCO?

 You can find the definition of the error codes here: https://github.com/NordicPlayground/fw-nrfconnect-zephyr/blob/master/lib/libc/minimal/include/errno.h

57 means that the socket is not connected.

 Yes. The nRF9160 supports both ePCO and "legacy" PCO. You can control which is used with our %XEPCO AT command.

Now the board is connecting, but I can't login to the server.

 Are you using TLS? OR any other form of security?

Also, it does not look like you are able to connect to the server. If you had, you should either see a line saying "MQTT client connected!" in the log or "MQTT connect failed" with an MQTT CONACK error code explaining why the broker refused the connection.

I changed Host name for IP address: 5.196.95.208. This is mosquitto server for test.

 Could you try mqtt.eclipse.org instead of test.mosquitto.org? When I do a DNS lookup for mqtt.eclipse.org I get 137.135.83.217

[p.durys]

I'm not using any encryption. For first time that can complicate the communication. 

This is log from modem when I changed host for eclipse:
