-## Steps 
- 
-* You need an Android device, and to download the Blue\_SPP chinese app. I wouldn'​t recommend using your phone or anything having access to personnal information,​ the required permissions are quite... large. 
-* Connect to the BLUE\_SPP bluetooth device, using 1234 as PIN and 115200 as baudrate. 
-* Enter the _command_ mode: `#​AT#​SET=***#​` where *** is a multiple of 5 sec. 1 => 5s, 2 => 10s, ..., 9 => 45s (9 is the maximum value). I guess it's an inactivity timeout. Every successful command should be answered by "​OK"​. 
-* Get the current parameters: `#AT#GET#` 
-* Set the name of the device: `#​AT#​NAME=newName#​` 
-* Set the PIN code: `#​AT#​PIN=xxxx#​` 
-* Change the MAC address: `#​AT#​MAC=xxxxxxxxxx#​` 
-* Change the baudrate: `#​AT#​UART=B,​S#​` where: 
-  * B is the baudrate setting, between 0 and 8: 
-    * 0 => 2400 
-    * 1 => 4800 
-    * 2 => 9600 
-    * 3 => 19200 
-    * 4 => 38400 
-    * 5 => 57600 
-    * 6 => 115200 
-    * 7 => 128000 
-    * 8 => 256000 
-  * S represents the parity 
-    * 0 => No check 
-    * 1 => Odd 
-    * 2 => Even 
-* Check the new settings: `#AT#GET#` 
-* Exit the command mode: `#​AT#​SET=0#​` 
-* Power-cycle the BT module to apply the new settings
