Introduction

BLE technology enables electronic products to bridge with smartphones, offering advantages over wireless technologies such as Wi-Fi and Bluetooth 2.0, including lower power consumption, faster connection, and longer communication range. The RF-BM-4044B2, RF-BM-4044B3, and RF-BM-4044B4 BLE modules use TI's CC2640R2F as the core processor. The modules operate in the 2.4 GHz ISM band with GFSK modulation, supporting 40 channels with a maximum 2 MHz channel spacing, customizable large advertising packets up to 232 bytes, 3 fixed advertising channels, and 37 adaptive frequency-hopping data channels. The physical layer can be combined with classic Bluetooth RF to form a dual-mode device, and the adjustable 1 MHz and 2 MHz spacing provides better protection against adjacent channel interference. The modules feature a wide output power range (-21 dBm to +2 dBm) and -97 dBm high-gain receiver sensitivity. Designed to rapidly bridge electronic products with smart mobile devices, these modules are applicable to a wide range of electronic devices with such requirements.

Features

• BLE 5.0 protocol stack development: 2× data rate, 4× communication range, and 8× advertising payload length compared to 4.2
• Manual physical layer bandwidth adjustment for optimized communication range and data rate
