Microsoft Azure is changing its root certificate for IoTHub and we have to do some testing with this new certificate on a specified endpoint. Specifically : The credentials for the test environments are:
IoT Hub endpoint : g2cert.azure-devices.net
Connection String: HostName=g2cert.azure-devices.net;DeviceId=TestDevice1;SharedAccessKey=iNULmN6ja++HvY6wXvYW9RQyby0nQYZB+0IUiUPpfec=
More info here.
I am successfully doing this with MQTTfx by tracing all messages via wireshark
but I can’t do this with the modem and it returns +KTCP_NOTIF: 1,13 everytime.
Is there a way I could know if a TLS handshake has been made?
Other than the new root certificate now SHA384 might be used (Microsoft claims sha256 will work also) which the HLxx series supports.
