Not connecting to nRFCloud

[Yano]

Hi, we have an nRF9160DK (0.8.3) and it does not connect to the nrfcloud.

We have updated to the latest firmware 1.0.0

We only have nb-iot here so we  didn't use the iBasis sim, instead using a vodafone V-Sim (which is active). 

Are we missing a step here?

Thanks

Hi Dirdik,

We're under pressure here, so to speed things up we purchased a new DK rev 0.8.5.

But....it will not update its firmware.

Any ideas please?

Yano, quick question.

Now that you have Vodafone NB-IoT SIMs, did you ask Vodafone if you can use dynamic IP addresses on their network with those SIMs?

Our trial NB-IoT SIMs from Vodafone only support connection to whitelisted IP addresses (of which we are only allowed to supply two addresses) and therefore would not support AWSs dynamic range of IP addresses for the AWS IoT core. Which is what you need to connect to in order to get to nRF Cloud.

Thanks for that.

Wow I never though of that, so effectively Vodafone won't allow the traffic through!

I will contact them and ask but it seem very limited.

How did you get over this problem?

I set up an EC2 instance on AWS and set it to a static IP address. From there, I can send data to the EC2 instance which has a UDP Server set-up on it and it can forward data to elsewhere.

Cool sounds like a good solution, but first I'll ask Vodafone if they can add an IP range to our test, do you know the AWS IP address range? It does say in the form "provided that the IP ranges belong to the customer" but I'll try first.
