BL871E2-HI is an ultra-compact RF front-end module optimized for cost-sensitive and space-constrained applications


London– Telit announced the BL871E2-HI, a dual-mode Bluetooth 4.2 host controller interface module with embedded chip antenna and audio support. The ultra-compact component is optimized for efficiency and simplicity in end-device design, delivering reliable Bluetooth functionalities with robust endpoint security, leveraging the processing power and external Bluetooth stack of the host application processor.  The module includes certifications, all hardware features that reduce development costs, bill of materials, and time to market.

Ideal for quick-turn projects, the BL871E2-HI seamlessly speeds up device design across a wide range of industrial and consumer applications areas. The 9.7x10.1mm, 18-pad LCC component delivers basic rate (BR), enhanced data rate (EDR) and low-energy (LE) connectivity, for applications such as scanners & printers, mobile point of sales, m-healthcare, industrial gateways, and for audio equipped devices across all areas of the electronics industry.

The BL871E2-HI is SRCC (Radio Transmission Equipment Type Approval – China), RED (Radio Equipment Directive Compliance – Europe) and FCC (Federal Communication Commission Type Approval – USA) certified; and is qualified and listed as a Bluetooth 4.2 controller subsystem. It integrates the company’s portfolio of Bluetooth modules, directly addressing the demand from the rapidly growing BT/BLE-IoT market.

The BL871E2-HI is a hardware-only product. It requires no additional external supporting components to deliver Bluetooth functionality to the host device. The required Bluetooth stack is not included with the module to maximize bill-of-material flexibility. Either a customer-provided or Telit-sourced Blue Code +SR protocol stack must be made to run in the host processing environment to complete the solution.

In addition to efficient performance and low power consumption, BL871E2-HI includes value-added features that further streamline development:

  • Supports Android, Linux and Windows Bluetooth stacks
  • Class 1 TX power up to +12 dBm
  • Receiver Sensitivity: -95 dBm
  • UART, PCM and I²S interfaces
  • BR/EDR 128-bit hardware encryption accelerator
  • Scatternet: Up to 3 simultaneous piconets – 1 master and 2 slaves
  • Fast Automatic Frequency Hopping (AFH) algorithm
  • Support for all voice air-coding schemes
  • Assisted mode for HFP 1.6 Wideband Speech (WBS)

Integrators and manufacturers designing with the BL871E2-HI have access to comprehensive development and integration tools including a Raspberry PI 2-based evaluation and development kit with extensive software and support resources.
