    bme280_cal_meas_delay

    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?

    Re: bme280_cal_meas_delay

    Actually the return value of bme280_cal_meas_delay is us. 

    You can see the parameter define in bme280_defs.h,  we convert all value from ms to us when we calculation.

    So you can directly call delay_us.
