In this paper, the impact of the number of devices on the communication interference in Bluetooth Low Energy (BLE) is studied. The reliability of BLE communication in real life is partially revealed, by investigating the channel hopping features inside. The reliability drawbacks inside BLE are raised and they serve as the basis for future improvement. The reliability is analyzed in terms of the time of the first collision and total collision probability. The result shows that both channel selection algorithms (CSAs) from BLE are not able to deal with interference effectively.
