BT860 Series

Recommended for New Design (RND)

Overview

The BT86x series of UART HCI modules leverage the Cypress CYW20704 A2 chipset to provide exceptionally low power consumption with outstanding range for OEMs needing both Classic Bluetooth and Bluetooth Low Energy support. The Bluetooth 5 core specification shortens your development time and provides enhanced throughput, security and privacy. 

The BT860 modules are ideal when designers need both performance and minimum size. For maximum flexibility in integration, they support a host UART interface, I2S and PCM audio interfaces, GPIO, and Cypress' GCI coexistence(2-Wire). The modules provide excellent RF performance and identical footprint options for integrated antenna or an external antenna via a trace pin. 

These modules present a Bluetooth standard HCI interface with support for Linux / Android and Embedded Bluetooth software stacks for operating system backed devices. Additionally, Laird has partnered with SEARAN for support of their ultra small, flexible ‘dotstack’ platform for embedded Cortex M3 and M4 implementations.

FAQ

BT8xx and HID Proxy Mode: As a customer, what equipment do I need to enable HID mode?

A programming jig can be used for loose modules (BT800/BT810). You should consider obtaining the CSR-SPI adaptor although a USB interface also works. If the modules need to first be soldered to your PCB, the USB/SPI interface should be externally available to a PC. The programming PC should be running the Windows 8 operating system.

BT8xx and HID Proxy Mode: Is Windows 8 the only way to program the BT8xx?

You can use Windows 7 to run CSR Pstools to enable HID proxy mode. But you cannot do it for a second time because Windows 7 does not ‘switch’ to HCI mode. HCI mode is required to run the Pstools over a USB interface.

BT8xx and HID Proxy Mode: Will the BT8XX work with my BT keyboard and mouse?

This depends on your computer’s operating system and in which mode you have the BT8xx configured.

If the BT8xx is configured in HID mode, it will work with the following:

BLE Keyboard and Mouse in Computer BIOS screen

BLE Keyboard and Mouse in Windows 8

Classic BT HID keyboard and mouse in Windows 8

If the BT8xx is configured in HCI mode, it will work with the following:

Classic BT HID keyboard and mouse in Windows 8

BLE Keyboard and Mouse in Windows 8

Classic BT HID keyboard and mouse in Windows XP and 7.
