Get temperature
Purpose: Used to get current temperature.
struct __attribute__ ((packed)) get_temperature_request_t { uint8_t cmd; // 0x00 uint8_t tzone; // 0x00:CELL, 0x01:RSX }; struct __attribute__ ((packed)) get_temperature_response_t { uint8_t status; int8_t temperature_hi; int8_t temperature_lo; };
- Temperature in celsius: sprintf("%d.%d", temperature_hi, (temperature_lo * 100) / 256);
