Does HC-06 support master mode?

Does HC-06 support master mode

The answer is: Yes ,if you buy from DSD TECH or ModuleForces

When a master HC-06 module is to be paired with a slave hc-06 module, note the following:
1, PIN is the same.For example, if the master module pin is 1234, then the pin of slave module must also be 1234
2, The master module will remember the paired slave module. If you want to pair the second slave module, make sure that the master module   clears paired slave module.(give a hign level to PIN26 , master module will clear paired module)

It is important to note that when hc-06 is in the master mode, it can not specify which slave module to connect to. Only connect to the first slave HC-06 module it finds.

Yes, if you think this module is too simple, please select hc-05 module.  You can also buy this HC-05 from amazon.( buy link from amazon.com)
