STEVAL-BTDP2

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).

Pad can be reconfigured via SW as input for external 32.768 KHz to allow lower power consumption in deep sleep mode and sniff mode. 7 GPIO08 General purpose I/O 8 GPIO07 General purpose I/O 9 LDOUT 1.8 V LDO output, max 10 mA 10 GPIO01 General purpose I/O LED2 is connected to this GPIO, LED2 is ON when Bluetooth link is up 11 GPIO02 General purpose I/O 12 GPIO03 General purpose I/O 13 GPIO04 General purpose I/O LED3 is connected to this GPIO, LED3 is ON when SPBT3.0DP2 is in Active State 14 GPIO06 General purpose I/O 15 GPIO05 General purpose I/O Boot pin used for firmware downloading LED1 is connected to this PAD Reset - connected in parallel to onboard reset switch DocID030682 Rev 1 3/7 I/O connections STEVAL-BTDP2 Factory configuration - different configurations can be chosen (see the SPBT3.0DP2 datasheet). 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. Figure 2: AT command prompt 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. 4/7 DocID030682 Rev 1 R 10 N .M . 4 3 2 1 U SB M ALE C O NN EC TO R J2 R4 N .M . +3.3V_C P210 2 C8 100 n C2 10μ 6.3V +5V _U SB (VCC ) TP 2 C1 100 n 6 5 4 V out B yP ass V in D4 3.3V D3 D1 GND D2 2 +3.3V 1 2 3 C 12 10 μ 6.3V LED 1 G R EE N R2 470 O hm V out U 1A 1 M C P 1701 T-3302 E/TT GND IC 5 U SB U F01 W 6 C 11 100 n 3 2 GND 1 5 4 4.7K R9 C 13 1μ F 1 2 3 4 5 6 7 DC D RI GND D+ DV dd R E G IN IC 4 C4 10 n R1 0 O hm C5 22 μ 6.3V (TA N T.) +3.3V_H C C P 210 2 R8 4.7K NC NC NC NC NC NC NC 21 20 19 18 17 16 15 V in V out R XD _C P 2109 .
