SPWF04Sx MQTTCONN problem with Azure

I can't connect via MQTT to an Azure server.

I have a dedicated DeviceID with Primary and Secondary keys on an hypothetical XXX Azure portal.

So I generated my Shared Access Signature from the primary key and tried to connect at port 8883 (TLS) with,8883,,2,,SharedAccessSignature,DeviceID,,,,,


and MQTTCONN command always return "Certificate Error 23" (but no certificates are present on the portal).


I tried with several MQTT clients and they let me connect without problems with these credentials (and without any certificate).


Thanks for helping me.
