AWS IOT IP range

[Yano]

Hi, I need to white list the AWS URL used by the nRF9160 dev kit asset tracker example, could someone tell me what it is?

Thanks

If I'm not mistaken. The Asset Tracker uses AWS IoT Core via MQTT, this uses a dynamic range of IP addresses and has no one specific IP address.

I know it's dynamic, what I need to know is the URL not an IP address.

Probably this from the aws_fota sample:

config MQTT_BROKER_HOSTNAME
	string "AWS IoT MQTT broker hostname"
	default "a2n7tk1kp18wix-ats.iot.us-east-1.amazonaws.com"
	help
	  Default is set to be the NRF Cloud MQTT broker

Also found deep inside the nrf_cloud sub-system

Thanks for that, its some URL!

I presume Vodafone can open up their firewalls for amazonaws.com and it will allow this through!

I doubt that, if you are on the same trial contract that I am on with Vodafone. I had to get creative to get around the whitelisting of 2 IP addresses only.

They told me last week that they have opened it up to URLs.... seemingly?

I'll let you know how it goes.

As a mater of interest what fixed IP address worked for you and are they still working?

[MJD093]

I used an EC2 instance with a static IP address to send data to AWS. So I just gave them the static IP for whitelisting.

Hi MJD093, can you please give some more details of how you did this? What application did you run to forward the TCP packets? Thanks

Unfortunately I can not go into anymore detail on this.
