Frequently Asked Questions

Which Bluetooth audio profiles does the RN52-I/RM116 support for wireless stereo streaming?

The RN52-I/RM116 supports A2DP for high-quality stereo audio streaming, AVRCP for remote playback control such as play, pause, and skip, and SPP for serial data communication. These 3 profiles together cover the requirements of most consumer Bluetooth speakers and headphone designs operating on the 2.4 GHz band at data rates up to 3 Mbps under Bluetooth 3.0.

How does the 3 V to 3.6 V supply range of the RN52-I/RM116 influence battery selection for a portable speaker design?

The narrow 3 V to 3.6 V supply range aligns directly with a single-cell lithium-polymer or lithium-ion battery discharged to 3.0 V cutoff, allowing the module to be powered directly from the battery without a boost or LDO regulator in many designs. A protection circuit and low-battery shutdown threshold at 3.0 V must be implemented to keep the module within its operating specification at the end of discharge.

For a compact Bluetooth audio product, what advantages does the 50-pin SMD package of the RN52-I/RM116 offer over a discrete Bluetooth chipset implementation?

The 50-pin SMD module integrates the Bluetooth radio, RF matching network, firmware, and audio codec into a single pre-certified assembly measuring approximately 26.7 mm x 14.0 mm, eliminating the need for RF layout expertise and FCC/IC/CE re-certification. This reduces hardware development time by several weeks and lowers the PCB layer count compared to a discrete chipset implementation.
