Connecting to AWS IoT through MQTT

Just checked, Edvin... My SIM card was indeed out of data!

I recharged the card and voila! I was able to communicate with the Thing on AWS IoT Cloud!

Thanks once again for your help!

Cheers,

Bojan.

Hello Bojan,

If you are using the iBasis Sim card you can check it on nRFCloud. Log in with the same account that you used to activate the sim card.

Then go to the SIM CARDS tab to the left and you should see the status of your sim cards. Click refresh beneath the SIM card you are using to make sure the information is up to date. You can use the "+ Buy Data" option to refill the SIM Card:

NB: I am not sure whether it is still like this, but it was at some point in time.

If you buy 10MB for an iBasis SIM card, you top it up to 10MB. This means that if you have 5MB left, and buy 10MB, you will only actually receive 5 new MB, and the new remaining data will be 10MB in total. I am not sure if this has changed or not, but if you are all out, there is no loss in buying 10MB :-)

BR,

Edvin

Hey @Edvin!

Thanks for sharing that info with me! That also was on my TODO list ! :-)

I am using a SIM card that came with nRF9160DK board (iBASIS eSIM). Where can I actually check how much data is left and how can I recharge the card?

Regards,

Bojan.

Hello Bojan,

E: Failed to connect to cloud, error: -10

is probably just a following error from the previous:

E: mqtt_connect, error: -116,

so let's focus on that one for now.

116 probably refers to ETIMEDOUT. I asked a colleague of mine, and he said that he had seen that a couple of times if the SIM card was out of data. Since this is fairly easy to check, can you either try to refill the SIM card, or to try another SIM that you know has more data left?

Best regards,

Edvin
