Chapter IV: Application Specification
4.1 Module application circuit
Refer to the following circuit for module minimum system
3S
in
Figure 4-1 Module recommended minimum system
Figure 4-2 Connection between host and module pin
The pins that need to be connected to the host when the module works normally are as shown in
figure 4-2. At least four IO ports are required to control the module. PWR_CTRL refers to low lower
control pin; the falling edge enters power dissipation, while the rising edge exits lower power dissipation.
PIN_MODE refers to command and transparent transmission mode switch; pin low level is the command
mode, while the high level is the transparent transmission mode. BT_CTRL refers to the broadcast control
pin; it enters broadcast state at low level and the broadcast stops at high level.
4.2 Precautions on module usage
In order to ensure that RE performance of module is the most effective in applications, users shall
follow the following principles in use:
1. It is recommended to use DC stabilized power supply for the module. Power supply ripple
coefficient shall be as small as possible. The module shall be grounded reliably. Please pay attention to the
connection between positive and negative poles of the power supply. Reverse connection may cause
permanent damage to the module;
2. It is recommended to place the module at the open space of bottom plate edge and the antenna shall
face outwards;
3. PCB board (double-sided board and multi-layer board) below the antenna in the module needs to be
cleaned and cannot be coated with copper, i.e. there shall be no grounding or signal trace for all layout
layers below the antenna;
4. It is best not to have metal devices near the antenna, otherwise the communication distance of
modules will be shortened to varying degrees in different environments.
Figure 4-2 Module PCB layout
Chapter V: Functional Specification
5.1 Networking function
The transparent transmission module is temporarily only used as a slave device to connect to piconet
with master device. The existence of these interfaces not only greatly expand the connection mode of the
module but also can enable users to dock with the modules and realize the network transmission of data;
5.2 Serial port framing mechanism
URAT has a framing mechanism. The continuous transmission is one frame, but the number of bytes
per frame must be less than 1500 bytes. The framing is related to the low power mode. In low power mode,
transparent transmission module will ignore all the data received. The module must be woken up before
data can be set and received.
5.3 Transparent operating mode
Serial port transparent transmission working mode is supported to realize data transfer from wired
serial port to Bluetooth wireless transmission or achieve transparent transmission to serial port through
Bluetooth wireless transmission. Transparent transmission working mode enables products of customers to
achieve the fastest and simplest wireless communication.
UART->APPËWhen uart sends data, the length of a packet to be sent needs to be determined by the
transmission interval and the connection interval of modules. The data of one frame cannot exceed 1500
bytes.
APP->UARTËAPP needs to be cached. Ble can only send 1500 bytes in one frame (the frame will be
dropped if there are more than 1500 bytes).
5.4 Command mode
Command configuration mode is supported to configure and read the device information of module as
well as the parameters configured by users. See 5-11 serial port command overview for details.
5.5 Echo mode
The module enters echo mode when the module is in unconnected state and PIN_MODE is high. At
this time, the data can be received at HCI_RXD terminal through HCI_TXD printing module to facilitate
debugging by users.
5.6 Serial port upgrade mode
The module supports the serial port online upgrading function. When the module is reset, 16-byte
IRUPDWFRPPDQG³ymodem´LVVHQWWRWKHPRGXOHDWDQ-bit length of 115200 baud rate and one-stop bit
no parity through thH VHULDO SRUW 7KH PRGXOH ZLOO UHWXUQ WR ³&´ FKDUDFWHU DIWHU UHFHLYLQJ WKH FRPPDQG
which indicates successful entry into the serial port upgrade mode and waiting to receive the upgrade
program. It will be started according to the new program if the upgrade is successful, otherwise it will be
started from the original program.
5.7 Low power mode
The module enters low power mode when the module POW_CTRL pin is pulled low. At this time, the
module will no longer broadcast or receive the data sent by Bluetooth and the host serial port. It will exit
the low power mode when POW_CTRL pin is pulled high.

In command mode, the users control BLE transparent transmission module through the serial port
command, as shown in figure 5-1. The primary controller sends a command to BLE transparent
transmission module. BLE transparent transmission module will send an acknowledge frame to the
controller MCU after receiving the command and executing it to characterize the result of command
execution.

In transparent transmission mode, MCU sends data to the module, and then the module transmits to
the mobile phone through BLE protocol. The mobile phone sends data to the module through BLE
protocol, and then the module sends to MCU through the serial port, as shown in figure 5-2.
