To adapt to more Internet of Things (IoT) service scenarios, a new synchronous communication scheme was proposed in BLE 5.0. This solution enables devices to communicate through the periodic advertising synchronization establishment procedure (PASEP) without establishing a connection. PASEP can be divided into two steps. In the first step, a BLE device receives periodic advertising synchronization information from another device; in the second step, the BLE device periodically receives data using the received synchronization information. However, there are some problems in this process. In PASEP, there are only three channels available for use in the first step of PASEP, which leads to serious signal collisions when there are many surrounding devices. To solve this problem, we propose a novel synchronous communication scheme in this paper, which can greatly improve transmission performance while maintaining low energy consumption. The simulation results effectively verify the effectiveness of the proposed scheme.
