We present our study of pulsating subdwarf B stars achieved with both ground and space observations. During this part, we will mainly focus on a mode identification based on ground observations. A mode identification is a necessary step towards an application of asteroseismology to infer physical properties of the stars. Even though, there is a number of such methods, in our case, their application was limited only to multicolor photometry and rotational multiplets. This limitation turned out to be a consequence of both short coverage and high noise data. We will conclude summarizing what has been achieved with ground observations over years, heading towards our Part2 talk which will focus on space observations.
