Product details
Overview
SPBT3.0DP1 from STMicroelectronics is a Bluetooth 3.0 Class 2 module with embedded Data Package (DP) firmware supporting SPP, HID, and iAP2 profiles for iOS accessory integration. It operates at 2.4 GHz ISM band, delivers +4 dBm RF output power, supports UART host interface up to 2 Mbps, and implements bonding, encryption, sniff mode, and deep sleep for low-power operation in portable MFi-compliant accessories.
For engineers reviewing the SPBT3.0DP1 datasheet, SPBT3.0DP1 pinout, SPBT3.0DP1 application, or SPBT3.0DP1 equivalent, this module is selected for rapid Bluetooth-to-serial bridging in Apple-certified peripherals, where AT-command configurability, dual-mode (command/bypass) operation, and pre-qualified Bluetooth SIG listing reduce qualification time and firmware development effort.
Technical Context
The SPBT3.0DP1 integrates a Bluetooth 3.0 BR/EDR baseband controller and 2.4 GHz transceiver with on-module antenna matching. Its DP firmware implements a full AT command interpreter that manages link establishment, security (MITM-resistant pairing), and profile multiplexing - allowing concurrent SPP and HID connections while maintaining iAP2 compatibility with iOS devices via MFi co-processor handshake.
It supports dynamic UART baud rate switching (300–2,000,000 bps), GPIO control (14 configurable pins when StreamingSerial=FALSE), and power management modes including Active Status Mode (ASM) and Deep Sleep Mode (DSM), with wake-up via UART, GPIO, or Bluetooth event - enabling sub-100 µA standby current in DSM with external trigger capability.

| UART_TX | Transmit data output | CMOS-level UART output to host MCU RX; logic-high = 3.3 V, idle high |
| UART_RX | Receive data input | CMOS-level UART input from host MCU TX; accepts 3.3 V tolerant signals |
| RESET_N | Active-low reset input | Pulled high internally; driven low for hardware reset (min. 10 µs pulse) |
| WAKEUP | Wake-up request input | Edge-triggered input to exit Deep Sleep Mode; rising edge initiates wake sequence |
| GPIO1–GPIO14 | Configurable digital I/O | Software-defined as input/output with optional pull-up/down, open-drain, or interrupt (rising/falling/rising+falling) |
| ANT | RF antenna port | 50 Ω matched RF output; requires 50 Ω microstrip trace to onboard chip antenna or external connector |
Key Features
| Feature | Design Value |
|---|---|
| iAP2 protocol support | Enables certified communication with iOS devices for audio, control, and metadata - eliminates need for separate MFi authentication firmware |

FAQ
Does SPBT3.0DP1 require Apple MFi licensing for iAP2 use?
No - SPBT3.0DP1 contains ST's pre-certified iAP2 firmware and MFi co-processor interface logic. End-product developers must still complete Apple's MFi program enrollment and final product declaration, but no additional firmware development or cryptographic key provisioning is needed beyond standard DP AT commands like CpTest and IAP2Connect.
What is the maximum UART baud rate supported in bypass mode?
The SPBT3.0DP1 supports UART baud rates up to 2,000,000 bps in both command and bypass modes. This is confirmed in UM2077 Section 3.9.1 and validated across all DP firmware versions ≥2.0. Baud rate changes take effect immediately after the "AT-AB Baudrate Changed" response, with no packet loss during transition.
How many devices can be stored in the bond table, and what happens on overflow?
The bond table holds up to 100 paired devices. When the 101st bonding is initiated, the oldest entry is overwritten - a documented behavior in UM2077 Section 3.4.1. Each entry stores BD address, link key, and encryption parameters; erasure is atomic via EraseBondTable command with "AT-AB BondTableErased" confirmation.
Is antenna matching required when using the onboard chip antenna?
Yes - the SPBT3.0DP1's onboard chip antenna requires precise 50 Ω impedance matching via the integrated matching network (L1/C1/C2 per UM2077 schematic). Deviation from recommended PCB layout (e.g., ground plane cutouts, trace length) degrades RF performance, reducing effective range below the rated 10 m and increasing current draw during transmission.
