Hi Yikai

thank you very much for your prompt responding. I am new to BLE. are these Master/Slave correspond to Scanner/broadcaster.

In case of BLE,

-- The central device who is scanning for the BLE devices available in the range and initiates the connection is "Master".

-- And the peripheral device who is advertising is a "Slave".

BLE is a star topology, so master can connect to multiple slaves but a slave can be connected to only one master at a time. You can also refer CC2540/41 BLE Software Developer’s Guide for more infomation on BLE.

I hope this helps.
