FEATURES/SPECS

The BM77 is a fully-certiﬁed

Bluetooth® Version 4.0 (BR/EDR/

LE) module for designers who want

to easily add dual mode Bluetooth

wireless capability to their products.

Delivering local connectivity for the

Internet of Things (IoT), the BM77

bridges your product to Smart

Phones and Tablets for convenient

data transfer, control and access to

cloud applications.

This Bluetooth SIG certiﬁed

(QDID:B021961) module provides

a complete wireless solution

with Bluetooth stack on-board,

integrated antenna, and worldwide

radio certiﬁcations in a compact

surface mount package, 22 x 12 x 2.4

mm. It supports GAP, SDP, SPP, and

GATT proﬁles. Data is transferred

over the Bluetooth link by sending/

receiving data via transparent

mode over UART, making it easy

to integrate with any processor

or Microcontroller with a UART

interface. Conﬁguration is made

easy using a Windows® based GUI

or directly via UART by a MCU.
