Frequently Asked Questions
What is the operating range and Bluetooth class of the SPBT2632C2A-AT2 module?
The SPBT2632C2A-AT2 is a Bluetooth v3.0 Class 2 module, which provides a nominal operating range of approximately 10 m in open-air environments. Class 2 power output (around 4 dBm) balances transmission range and power consumption, making it suitable for short-range cable-replacement applications in IoT and consumer accessory designs.
How does the AT2 command set of SPBT2632C2A-AT2 simplify integration with UART-based microcontrollers?
The AT2 command set allows a host microcontroller to configure, pair, connect, and transfer data over Bluetooth using simple ASCII AT commands via a standard UART interface at common baud rates such as 115200 bps. This means no external Bluetooth stack library or additional firmware layer is needed, reducing development time and code memory requirements on resource-constrained MCUs.
Which Apple device connectivity profile does the SPBT2632C2A-AT2 support and what does it enable?
The SPBT2632C2A-AT2 supports the iAP (iPod Accessory Protocol) profile, which allows the module to communicate with Apple iOS devices such as iPhones and iPads as a Made for iPhone (MFi) certified accessory. This enables applications such as health monitors, audio accessories, and point-of-sale readers to exchange data with iOS devices over a Bluetooth v3.0 serial link.
Does the SPBT2632C2A-AT2's integrated antenna affect PCB design constraints for certified products?
Yes, the integrated on-module antenna of the SPBT2632C2A-AT2 requires a keep-out zone on the host PCB beneath and around the antenna area, typically 5 mm to 10 mm, free of ground planes and traces. However, it eliminates the need for an external antenna connector, RF matching network, and separate antenna component, which significantly reduces BOM cost and simplifies FCC/CE regulatory certification.
