1. BLE4.1 Module Brief Introduction

1.1. Function Introduction

This is a Slave Module which support bridge mode (Transparent

Transmission) and direct-drive mode. Module can automatically

broadcast after the initial setup, with a specific APP phone will scan and

dock with the module, after pairing success the APP can monitor the

device through BLE protocol.

In bridge mode, user’s CPU can communicate with the mobile

device in two-way through module's UART. Users can also manage and

control certain communication parameters through specific commands.

The detailed meaning of the user data is defined by the up-application.

Mobile devices can write to the module through the APP. And the data

written will be sent to the user’s MCU through SPI. Then the module

will transmit the data package from user MCU to the mobile devices

automatically. In the development under this mode, the user needs to

undertake the code design for MCU code, and the code design of APP

for smart mobile terminals.

In Direct-Drive mode, users take simple periphery expansion to the

module. And APP drives the module directly through BLE protocol, to

implement the monitoring and control of the module by smart mobile

devices. In this mode, users only need to do the code design for smart

mobile terminals.



1.2. Main features

Easy to use, no need of any experience of Bluetooth protocol stack

application.

Support Bluetooth Multi-connection data transmission function.

Support connection solutions:①Module acts as a Slave that can

connect with 4 Masters; ②Module acts as a Master that can connect

with 4 Slavers; ③When module Master and Slave integration that

can connect with two Masters or Slavers.

UART design for user interface, full-duplex bi-directional

communication, and supporting the minimum baud rate of 75bps,

maximum of 375000bps.

Supporting bridge mode and direct-drive mode (no need of

additional CPU), direct-drive mode support SPI/UART.

Default connection interval of 40ms, which make quick connection.

With the increase of connected devices, connected devices

connection interval will gradually increase after 25ms.

Support software reset module by AT/SPI command, and access to

MAC address.

Support adjust Bluetooth connection interval by AT/SPI command,

and control of different forwarding rates (Dynamic power

adjustment).

Support to adjust Tx power by APP/SPI/UART command, modifying



broadcasting interval/connection timeout time/product connection

delay/serial port baud rate/module name.(all settings will power

down save)

Serial port data package length, less than or equal to

80byte(automatic distribution)

Multi-connection support connect with 4 device at the same time,

two-way connection rate of 80byte/s.(If long time TX/RX data, then

support maximum of 3 devices.)

Supporting modify module name/serial port baud rate/product

UUID through APP/SPI/AT, custom broadcast content, broadcast

cycle, all power down save。

Support mobile device remote reset to the module through APP /SPI

/ AT and set Tx power.

Support mobile device adjust BLE connection interval through

APP/SPI/AT, power down save (Dynamic power adjustment).

Operating all IO extend through APP/SPI/AT.

Supporting connection status/broadcasting status tip pin/general IO

Configuration.

16 two-way programmable IO port, all low power operation (Applied

in lighting control, remote control toys, and various relating

input/output/on/off things).

2 ADC input(12 bit), Enable/Ban, free configuration of sampling cycle.



Mean filter setting.

（Applied to measuring temperature and humidity, luminosity, etc.）

6 programmable PWM output IO (2MHz at most).

（Applied dimming, speed, etc.）

Module end continuous acquisition RSSI (Anti-lost alarm

application).

Supporting device power level tips/power level read.

Supporting internal RTC real time clock，APP end can always sync

calibration.

Supporting IO configuration and output state saving function,

customizable initialization state.

Supporting shallow/deep recovery mode, flexible restore user data,

and save product configuration 。

Supporting obtain Bluetooth connection state through UART/SPI.

Supporting low enable and pulse enable mode, and remote

shutdown.

Ultra low power standby mode.

SPI Protocol use message mechanism to feedback data, data read effective

when “INT”Low.

SPI Protocol question and answer mode interaction data, data read and Write

determined by Register Read/Write.

SPI Data containing: Data Head、data length、Register Address、Data、

Check.

Data Head：Fixed：0xFE。

2.3. Serial Ports Command Format Description

1. Serial Port send AT COMMAND （Detail see Table 2-1）. If command success,

it will return “AT+OK\r\n”. If failure, it will return error state.

2. Serial Port read/write determined by register Read/Write.

3. Query register which has read attribute, you can add “?” after

the AT COMMAND,then you can get the relevant content.

Note: All AT COMMAND will end with“\r\n”.

AT COMMAND:

AT+D0=xxx\r\n

SPI DATA:



Write Bluetooth data：Write data content which need to send

Read Bluetooth data：no need to fill in data

Notes:

This command can only send data to the device 0 which has been connected.

UART data, each packet allows data maximum of 80 bytes (including AT commands).

SPI data, each packet allowsdata maximum of 80 bytes.

The module will automatically subcontracted, 20 bytes per packet

The maximum data Interval = (maximum amount of data (total number of bytes (not including AT

command)) / 20) * Maximum transmission interval.

Please reduce the occurrence of the circumstances of each packet interval of data is far less than

the maximum Bluetooth connection interval, this easily lead to data loss.

UART data transmission volume calculation method to calculate the amount of data sent as follows:

HEX mode: The actual number of bytes sent = (total number of bytes of data packets - AT

commands (10 bytes)) / 2

Character mode: The actual number of bytes sent = total number of bytes of data packets - AT

commands (10 byte)

Data transmission interval not less than 250ms
