SIM 800 GPRS modem for HTTP GET and POST to AWS IoT and AWS API gateway

Question

I was trying to POST and GET some JSON data to and from the AWS cloud respectively using the SIM 800 module. I\'m initially trying it out directly from my PC over a terminal

Answer 1

Microsoft Azure has recently upgraded TLS requirements with the effect that "If a client tries to negotiate TLS 1.0 over such a scenario, the request will fail with connection reset". This explains why my application now fails as the SIM800 module only supports TLS 1.0.

AWS may have done the same. It seems that there is an ongoing move to deprecate TLS 1.0 and according to SSL and TLS, what is the Big Deal About June 30th? 30 June 2018 is the cutoff date at which point TLS 1.0 will not be supported if you want to claim PCI compliance.
