3.1. Working Mode
USR-BLE100 has 4 modes:
Master Mode
Slave Mode
Broadcast Mode
Mesh Networking Mode
<Note>
The module default factory mode is slave pattern, user can use master device to search.
3.1.1. Master Mode
USR-BLE100 support master mode that can connect with a slave device. In this pattern, user can search
devices around and choice the slave device need to connect. User also can set the MAC address of the slave
for default link, the device can find this pattern to connect when it power on.
for default link, the device can find this pattern to connect when it power on.
<Note>
The USR-BLE100 module in Master mode, it need to connect another USR-BLE100 which is in Slave
The USR-BLE100 module in Master mode, it need to connect another USR-BLE100 which is in Slave
mode to realize point to point transparent data transfer. It can’t connect other brands’ device to realize
transparent transmission because of the incompatible protocol.
transparent transmission because of the incompatible protocol.
3.1.2. Slave Mode
USR-BLE100 support slave mode, in this mode, device completely conform to BLE 4.1 protocol and
compatible with 4.0 protocol, user can develop APP according to protocol. This mode contain a serial
transceiver Service, user can find it by UUID. There are 2 channels, read and write, user can transfer data
through those channels.

There is no need for user to concern protocol if use the master of USR-BLE100 connect with slave, the
serial ports of two devices can transparent transfer data immediately. It develop a easy wireless transmission
channel for user.

The question how to use BLE protocol to communicate is introduced in software design manual.

3.1.3. Broadcast Mode
USR-BLE100 support broadcasting mode, which support one-to-many broadcast. User can set module
broadcasting data through AT instructions. Module can consistent broadcast in low-power pattern, be used to
ultra-low power, small-data-sets, simplex transmission application occasions, like wireless measurement,
indoor location and so on.

Module has built-in iBeacon protocol, user just need a button battery and set parameter through AT
Module has built-in iBeacon protocol, user just need a button battery and set parameter through AT
instruction to make it a iBeacon device. Following chapter will detailed introduce it.
3.1.4. Mesh Networking Mode
USR-BLE100 support Mesh network mode, can connect many modules with net easily. By using star
