http_client network error on thingy91

[rupcar]

Hello,

I am trying to use http requests on Thingy91 and therefore I tried with the sample from zephyr/samples/net/sockets/http_client.

I can build the project without any problem but when I try to run it, I get the following error when I open a putty terminal:

I did not change anything in the code, and I was supposing it was not a network problem since I activated my SIM card and I can run the asset_tracker and see the data in nrFcloud without any issue.

I am using the nrfConnectSDK 2.0.0, and the SIM is from twilio.

Best regards,

C

Hello Carole,

I've been running for a few time the https_client now but I get an error half of the time: either the "getAddrInfo() failed, err 115" or the "connect() failed, err 116". DO you have any ideas where this could be coming from ?

The errors 115 & 116 are pointing towards a lost network connection. 

To find out possible reasons for that, you need to increase the log level at this point. There are several options to do so, but based on how the HTTS Client is structed, I would start with enabling CONFIG_LOG & CONFIG_LTE_LINK_CONTROL_LOG_LEVEL_DBG in prj.conf of the sample.

Hello,

Thanks for the answer.

Here is when it works:

I am not really familiar with all that, and did not find much help online.It seems like it might be an unstable connection during the call to getAddrInfo() but what I don't really get is why it is still working half of the time.I'm using a Twilio SIM in Switzerland and I though it was supposed to have great connection.

I know I am also having a 0 answer from recv() which I'm still trying to figure out but I'm not sure it is coming from this since it works some of the time.

Thanks!
