STEVAL-BTDP2
USB dongle for the Bluetooth® class 2 SPBT3.0DP2 module
Data brief
Description
The STEVAL-BTDP2 dongle demonstration tool
is exclusively designed for quick and easy
SPBT3.0DP2 module evaluation.
The dongle includes an RF antenna and a USB
connector to allow PC communication with the
Bluetooth
®
module and power the dongle.
The STEVAL-BTDP2 includes downloaded
firmware so you can create a Bluetooth
®
link
using simple AT commands (see user manual
UM2077 on www.st.com for the complete list of
AT commands).
Features
Based on the V3.0 Bluetooth
®
class 2
module SPBT3.0DP2
USB interface and power supply
Reprogramming support via USB interface
Reset button
On-board Antenna
RoHS compliant

2.2
Reset switch
Reset switch SW1 on the dongle forces the SPBT3.0DP2 module to reset and the
information figured below is shown on the PC.
The actual BDAddress number may be different on your machine.

2.3
Bootloader jumper
When Bootloader jumper (JP1) is closed, the SPBT3.0DP2 enters Bootloader mode after
reset.
Figure 3: Reset switch and Bootloader jumper
Bootloader mode is used to update the module firmware.
The STM32 Flash loader demonstrator GUI (see user manual UM0462 on www.st.com)
can be used to update the SPBT3.0DP2 module.
A detailed description of the firmware update procedure can be found in user manual
UM2077 on www.st.com.
