The present disclosure relates to the electronic communication field and discloses a dual-Mode device and a method for achieving the simultaneous communication therein. The dual-mode device has a dual-mode protocol stack scheduling mechanism and uniformly schedules the transmission event of the Bluetooth protocol stack and the ZigBee protocol stack. The method comprising the following steps: after matching the dual-mode device with a Bluetooth host as a slave and the ZigBee target device as a control device, the dual-mode device conducting the Bluetooth connection maintenance according to preset interval and processing the information exchange with the ZigBee target device at each Bluetooth connection interval. Compared to the prior art, the present disclosure allows the smart devices to support two types of communication protocols, achieves the interaction between the smart devices using the two different wireless standards, and greatly improves the communication efficiency of network with the Bluetooth and ZigBee devices.
