Gateway to Sensor Protocol
The Intel® RSP provides a secure remote capability for command, control, status and data
collection via JSON Remote Procedure Call (RPC) over an encrypted MQTT channel.
CUSTOMERS ARE SOLELY RESPONSIBLE FOR CONFIGURING THEIR MQTT BROKER FOR
THE APPROPRIATE LEVEL OF SECURITY FOR THE DATA COLLECTED VIA THE DEVICES.
The Gateway Command set follows the JSON RPC 2.0 specification. JSON-RPC is a
