sim800c 支持哪些密码套件？

Question

我正在尝试与使用 SSL/TLS 但具有一些有限密码套件的服务器通信。
如何在我的 sim800c 中获取支持的密码套件列表，以查看它是否可以与服务器通信？

Answer 1

我创建了 @roberto-caboni 建议的测试环境。我测试了 SIM800L 和 SIM800C。密码套件相同。

结果是：

/* SIM800L firmware revision */
AT+CGMR

Revision:1418B05SIM800L24

OK

/* SIM800C firmware revision */
AT+CGMR

Revision:1418B08SIM800C24_BT

OK
