Vasileios Amoiridis 4c3bf788a4 iio: chemical: bme680: Fix sensor data read operation ... commit 4241665e6e upstream. A read operation is happening as follows: a) Set sensor to forced mode b) Sensor measures values and update data registers and sleeps again c) Read data registers In the current implementation the read operation happens immediately after the sensor is set to forced mode so the sensor does not have the time to update properly the registers. This leads to the following 2 problems: 1) The first ever value which is read by the register is always wrong 2) Every read operation, puts the register into forced mode and reads the data that were calculated in the previous conversion. This behaviour was tested in 2 ways: 1) The internal meas_status_0 register was read before and after every read operation in order to verify that the data were ready even before the register was set to forced mode and also to check that after the forced mode was set the new data were not yet ready. 2) Physically changing the temperature and measuring the temperature This commit adds the waiting time in between the set of the forced mode and the read of the data. The function is taken from the Bosch BME68x Sensor API [1].
