#MQRING - Received data on subscribed topic
When a message is received on the subscribed topic, an URC message is sent to all AT
commands interfaces. There are 30 messages slots available for incoming messages, and
it is responsibility of the user to keep them empty by reading them with #MQREAD.
• If the message queue is full, and a new message arrives, the following
URC #MQRING: 0 is received.
• Otherwise, for normal messages, the URC format is:
#MQRING: <instanceNumber>,<mId>,<topic>,<len>
In the Unsolicited fields section are described the URC message parameters not described
in the previous sections.
