FiPy LTE-M Amazon AWS-IoT

[Andrew Long]

Hello,

I have a FiPy which is working OK with LTE-M in the UK in that I have managed to successfully do an http get request on a webpage. I have also managed to get a GPS location from the attached pytrack 2.0 board.

What I would like to do now is send the location information over LTE-M to Amazon AWS (preferably AWS IoT but if not that then S3).

From reading around it seems I can use either http or mqtt to achieve this.

Can anyone point me to some instructions or some code to get this up and running on my FiPy?

Many thanks for any help you can offer.

Can anyone help me find the Root CA Certificate?

I've made a bit of progress, and found this: https://docs.pycom.io/tutorials/networkprotocols/aws/

The aws webpage has changed significantly since the instructions were written, but I think I've managed to do everything asked for.

BUT... I'm stuck where it says:

"Connect to the device via FTP and put the root CA certificate, the client certificate (*.pem.crt) and the private key (*.private.pem.key) in the /flash/cert folder."

Where do I get the root CA certificate from? (I got the client certificate and the private key during the previous steps, but no root CA certificate that I can see)

Thank you.
