It works with HTTPS server with RSA 2048bit public key and Elliptic Curve 256bit public key.

BUT, If I connect to a server with EC 384bit then I get HTTP error 751 (TLS handshake failure).

Is there a new modem firmware which supports contemporary TLS suite? My modem has firmare V1.11.1

lewisxhe commented 8 months ago

There is currently no firmware that supports EC formats

G7OCD commented 8 months ago

I don't think that is quite correct. EC256 keyed certificates are processed OK, just not EC384.

Can you confirm modem v1.11.1 is the latest?

lewisxhe commented 8 months ago

V1.11.1? This is not the modem firmware version. Send AT+SIMCOMATI to check the return result.

G7OCD commented 8 months ago

Because ATI and AT+SIMCOMATI provide different revision numbers......

ATI Manufacturer: INCORPORATED Model: A7670G-LLSE Revision: A7670M7_V1.11.1

AT+SIMCOMATI Manufacturer: INCORPORATED Model: A7670G-LLSE Revision: A011B17A7670M7 A7670M7_B17V01_230621

I need to check with SIMCOM
