1. Quick Start
This chapter aimes at getting start USR-BLE100 quickly. It’s recommended that user read this chapter
systemically and operate it according to instruction to make a scientific knowledge. Following chapter will
introduce specific details and instruction, user can read interested chapter directly.
If you have any question, feed it back to customer center please:

1.1. Hardware Testing Environment

Module slave mode is similar to smart devices on the market like Smart Band. This module support
standard BLE communication protocol, user can independent develop software and communicate by connect
module with master device like mobile phone. This test need the device which support ultra-low power
Bluetooth:
The device with BLE function and Android system V4.3 or above.
Iphone 4s version or above device with IOS7.0 or above operating system.

1.2. Data Transmission Testing

Take Android mobile phone as example:
Testing environment: Android 5.0
Testing software : Android Bluetooth Module Debugger and USR-TCP-Test
Use the USR-TCP-Test to open the serial number of the connected module, set the baud rate as 57600.
(User can use AT instruction to change parameter, following chapter will introduce it.)
Link light will flash once per second when module power-on. Using the Module Debugger software to
search (click magnifying glass button) , you can find the device named USR-BLE100, as shown in figure 1.
Figure 1 Module Debugger software
Click on the device to connect with it, as shown in figure 2, the LINK light will keep on.

Figure 2 Module Debugger software
Firstly, click on the “USR Service”. Then click the “DEBUG” option at the bottom. After it, click on “NOTIFY”.
When it turn to “STOP NOTIFY”, listening state begins. Now we can receive data through serial port. If user
want to send data, click on the upward symbol on the left, find out the “WRITE”, click it and user can type data.
After click “SEND”, serial will receive the data you sent.
Figure 3 Module Debugger software
Note: According to test, we found that for BLE, the IOS support better than the Android, both at searching
speed or connecting speed. This is caused by the different of operating and hardware.
2. Overview

2.1. Brief Introduction

USR-BLE100 is a module which support ultra-low power Bluetooth4.1, and this module support master
and slave, user not only can use both master and salve for transparent transmission, also can make wireless
data transmission to the traditional low-end serial device and the device controlled by MCU. User can develop
APP on the basis of standardized BLE protocol, make it a easy way to communicate with module. This module
support MESH network pattern and one-to-many broadcasting, also has built-in iBeacon protocol, user can
