Does UL865-EUD module supports TLSv1.2 server protocal version?
no, but we plan to support TLS1.2 in the next production firmware 12.00.xx9
Actually, we are developing IoT gateway with TLSv1.2 server that is why we needed it.
Can you share 12.00.xx9 firmware for application development purpose?
It is not yet released, if you want a beta address through your Telit contact/representative..
I checked server details and got that our server supports TLS 1.0 and TLS 1.1 as well.
I tried to communicate with the server but getting “+CME ERROR: 839” error.
