Works great.: Computers and Accessories

I had no problem using modules in my project. They are initialized with stop bits of zero and a baud rate of 9600 in AT command mode. A data sheet wouldn't hurt.

  • Master and Slave, two modes in one module; Use AT command to set master or slave mode.
Cons
  • Nothing here

Pros
  • Default baud rate: 9600; Default pairing password: 1234; Default name: HC-05
Cons
  • Appearance

Pros
  • Doesn't work with iOS
Cons
  • Weak set
