Sena's 20S speaks Hayes

The new 20S by Sena Technologies talks to their IPhone- and Android-Apps like an old modem using a rather largely modified Hayes Communications command set over its Bluetooth interface. This command set contains at least the following commands:

• AT+APPLY,%i
• AT+CONNECT
• AT+GET,%i,%i
• AT+GETSTR,%i
• AT+INFO
• AT+NAME
• AT+NAME,%s
• AT+PD
• AT+PDL
• AT+SCAN,%i
• AT+SCANSTOP
• AT+SET,%i,%s
• AT+SETSTR,%i,%s
• AT+STORE,%i
• AT+TEST

%i stands for an integer value and %s stands for a string value

Update: They're using the well-known SPP UUID 00001101-0000-1000-8000-00805F9B34FB
