Hi Regarding the BME280 driver from Bosch, the function bme280_cal_meas_delay returns the required delay in millisecs. The return value is stored in the variable req_delay and then used in the following function call: /* Wait for the measurement to complete and print data */ dev->delay_us(req_delay, dev->intf_ptr); It seems there an unit error, because the dev->delay_us provides an mricosecond delay. Is my understanding correct? BR Gilberto
