Introduction
This user manual details the GS-BT2416C2DB.xxx which is a Bluetooth Class 2 evaluation
board for GS-BT2416C2.H and GS-BT2416C2.AT1 Bluetooth modules including an RF
antenna. The suffix xxx identifies the firmware release. There is no suffix for HCI
commands and AT1 is the suffix for AT commands.
The GS-BT2416C2DB is a board with downloaded FW which enables the user to interface
the Bluetooth module with HCI commands.
The GS-BT2416C2DBAT1 is a board with downloaded FW which enables the user to create
a Bluetooth link with simple AT commands. AT commands are sent by means of the serial
line which is accessible by the DB9 connector.
The GS-BT2416C2DB.xxx board can be supplied by an external 5 V DC source or via the
USB port.

(This connection example is also given in the GS-BT2416C2.AT1 datasheet, Appendix A) Setup & connect Two PCs and two GS-BT2416C2DBAT1 boards are needed to perform the connection. Figure 7. Basic setup 12/19... -
Page 13: Steps To Connect
(Please refer to the GS-BT2416C2.AT1 datasheet Appendix A, for the meaning of the AT commands). ● Designate a GS-BT2416C2DBAT1 board to be used as "Client" and it has the address 0080E1000001. Hereafter this board will be referred to as "Client" ●... - Page 14 At this point the connection is established and GPIO1 (indicating the connection status) on both Client and Server boards becomes high. On the GS-BT2416C2DBAT1 board an LED is connected to GPIO1 and therefore the connection is also shown by an LED on.
-
Page 15: Macro Instructions
UM0472 AT commands appendix ● Disconnection To disconnect, the Client has to put its GPIO3 LOW (Command mode) (changing from high to low on GPIO3 appears on the Client PC screen as +READY) and sends the command: AT+BTDISCONNECT The result is the disconnection of the link Client / Server, and GPIO1 on both Client and Server boards returns to low (the LEDs go off). -
Page 16: Module Bt Address
Each module has its own address which identifies the module itself in the network. The above examples were used with addresses 0080E1000001 and 0080E1000002. Modules on the GS-BT2416C2DBAT1 board could have different addresses. Before starting to send commands, the module address can be found with the command AT+BTSETTINGS=? which shows the relevant information of the module including the BT address. -
Page 17: Point-To-Point Connection
UM0472 AT commands appendix Point-to-point connection Modules with AT commands firmware can only perform point-to-point connections. Only one connection can be activated at once. A module can be connected to several other modules, but it has to disconnect from the previous connection before activating a new one. -
