Root Certificate and BG95 Issues

Hi All

Are there any issues with TLS and root certifications such as BaltimoreCyberTrustRoot.

I am connecting to Azure Iot Hub, and I am able to connect and communicate without the root certificate.

Has anyone experienced this?

I have WIFI devices, which will not work without this certificate but on BG95 it seems to ignore it and still work,

In fact, the security policy of the certificate is determined by the server side, which has little to do with the model of the module。

before test it with module, pls validate with mqttfx tools first

I attached one succuessful AT log of Azure cloud as below
