Mbed BLE for communication between three devices

Hi every one. I have a project that needs to establish communication between several boards using Bluetooth. Is there a way to send data from two microcontrollers to the same destination board? We’ve been looking at the GATT client and server but it seems like that is only for one-to-one connection. We also checked the GAP service. However, the example code was showing how to send information to a phone and we are not sure how to build a connection and receive data on another board. Thanks in advance! We are new to Mbed and Bluetooth so any help would be much appreciated.
