FCC ID: S9N16C2
DESCRIPTION
GSBT2416C2DB.xxx is a Bluetooth Class2 Demoboard for GSBT2416C2 Bluetooth module including the RF antenna.
Suffix xxx identify the Firmware release : no suffix for HCI commands and AT1 for AT commands.
GSBT2416C2DB. is a board with a downloaded FW which enables the user to to interface the Bluetooth module with HCI
commands.
GSBT2416C2DB.AT1 is a board with a downloaded FW which enables the user to create a Bluetooth link with simple AT
commands.
AT commands are sent by means the serial line which is accessible by the DB9 connector.
SPBT2425C2DB.xxx board can be supplied by an external 5V DC source or via the USB port

DESCRIPTION
JP1
When the USB port is connected , the 5V USB is used ( by the 3.3V regulator) to
supply the BT module and the board itself
When USB port is used do not supply an ext. 5V to J4 power plug
USB port is not used for AT version
On board is present a level translator to adapt the BT module digital levels to the
RS232 standard levels.
When 5v input is used on J4 plug do not connect USB port
If connected to GND the module can perform the dowloading
applied to GPIO6 otherwise GPIO6 is at High level.
Not used for AT commands version
In AT version this switch is used to select Command / Data mode
On AT version this led shows when a Bluetooth conn ection is ON (led ON )
