From 2a321be376dbc3c534d3634fdcaf141aff79cd48 Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Wed, 29 Jun 2022 09:57:20 +0100 Subject: ipa: raspberrypi: Add sensor temperature to DeviceStatus Add an optional sensor_temperature field to the DeviceStatus structure. If a temperature measurement is available for a frame, the value is returned out through the SensorTemperature control in the Request metadata. Additionally, provide the sensor temperature value from the std::ostream &operator<< overload.
