| - | Since all the modules come with the same name of "HC-05", it may be difficult to work with multiple modules at the same time because if you pair multiple HC-05 with one Android phone or tablet, they will all show up as HC-05... How do you know which is which? | + | Since all the modules come with the same name of "HC-05", it may be difficult to work with multiple modules at the same time because if you pair multiple HC-05 with one Android phone or tablet, they will all show up as HC-05.

| This is compounded by the fact that the HC-05 can only be paired with one master at a time. Once you pair an HC-05 with a device, it will forget whatever device it may have been paired with previously. However, the device it was paired with previously may remember it yet it will not be able to reconnect unless you "forget" it and pair again. This can get aggravating, even more so if you try to explain that to a non-technical person. | This is compounded by the fact that the HC-05 can only be paired with one master at a time.
