The relationship between stellar rotation and magnetic activity is key to understand stellar dynamos. Recently, new debates on the role of the innermost layers of the star, have emerged within the stellar dynamo theory. A more extensive study of the long-term magnetic activity of partially and fully convective stars would allow us to understand whether their underlying dynamo is responsible for solar-like activity cycles. In this work, we study the magnetic activity of active and inactive M dwarfs. We analyze TESS light curves to characterize transient events and determine its rotation. We also study their magnetic activity using the log(R´HK) indicator derived from the CASLEO spectra.
