Product details

Overview

STEVAL-BTDP2 from STMicroelectronics is a USB dongle evaluation tool for the SPBT3.0DP2 Bluetooth® Class 2 module, integrating USB-to-serial bridge (CP2102), on-board antenna, reset switch, bootloader jumper (JP1), and preloaded AT-command firmware. It operates at 5 V supply, supports -40 °C to +85 °C case temperature, and enables PC-based Bluetooth link establishment and firmware reprogramming.

For engineers reviewing the STEVAL-BTDP2 datasheet, STEVAL-BTDP2 pinout, STEVAL-BTDP2 application, or STEVAL-BTDP2 equivalent, key considerations include USB-powered operation, GPIO accessibility via 15-pad header, AT command interface compatibility, bootloader mode entry via JP1, and integration of CP2102 USB-UART bridge and LDS3985 LDO.

Technical Context

The STEVAL-BTDP2 implements a hardware abstraction layer between a host PC and the SPBT3.0DP2 Bluetooth module, using the CP2102 USB-to-UART bridge IC to translate USB traffic into TTL-level serial signals routed to the module's UART interface (TXD/RXD). The onboard LDS3985 LDO generates stable 3.3 V for the module and CP2102, while the MCP1700/MCP1701 regulators provide 1.8 V (LDOUT) and auxiliary 3.3 V rails.

All 15 pads map directly to SPBT3.0DP2 module pins-including BOOT0, RESETN, LPO, eight GPIOs, SPI/I2S alternate functions, JTAG debug signals (JTMS/JTCK/JTDO/JTRST), and power/ground-enabling full hardware evaluation, low-power mode configuration (e.g., external 32.768 kHz LPO input), and firmware update via STM32 Flash Loader Demonstrator GUI.

FAQ

What firmware is preloaded on the STEVAL-BTDP2?

The STEVAL-BTDP2 ships with factory-loaded AT-command firmware compliant with Bluetooth v3.0+EDR Class 2 operation. This firmware enables immediate serial communication over USB using standard AT commands documented in UM2077, supporting device discovery, pairing, SPP profile activation, and bidirectional data exchange without initial programming.

How do I enter bootloader mode to update the SPBT3.0DP2 firmware?

To enter bootloader mode, close jumper JP1 and press the onboard reset button SW1. This asserts BOOT0 high and resets the SPBT3.0DP2, forcing it into STM32 system memory bootloader. Then use ST's STM32 Flash Loader Demonstrator (UM0462) via the CP2102 USB-UART interface to upload new firmware binaries.

Which GPIOs are connected to LEDs, and what do they indicate?

GPIO01 drives LED2 (green), which illuminates when a Bluetooth link is established. GPIO04 drives LED3 (green), indicating the SPBT3.0DP2 is in Active State (not sleep/sniff). LED1 connects to PAD2 (3.3 V), serving as a power-on indicator-not controlled by firmware or GPIO logic.

Can the STEVAL-BTDP2 operate without a host PC?

No-the STEVAL-BTDP2 is a USB-powered evaluation dongle with no battery or standalone power capability. It requires continuous USB host connection for 5 V power, CP2102 UART bridging, and command/data exchange. It lacks onboard microcontroller execution autonomy and is not designed for embedded deployment outside PC-based evaluation.
