For the Bluetooth Low Energy (BLE) connection events, a 2-dimensional Markov chain-based model is proposed in this letter, to compute and analyze the duration, duty cycle, power consumption and the maximum throughputs. A general application of peer-to-peer bidirectional data transmission is described in this model, by taking the influence of data transmission states of both the central and peripheral devices on connection event state into account. The impacts of  connection parameters, closing rules of connection events and channel quality on the performance are also analyzed. Experimental results show that the proposed model can accurately calculate the terms of average connection event duration, average energy consumption and the maximum throughputs of both the central and peripheral devices.
