I. Functions
This module is a BLE Pass-through Module based on the Bluetooth Low Energy standard
released by the Bluetooth SIG. This module can be controlled by the serial port and
MODE_CTL pin, and be wirelessly controlled through the host. Users can develop standard
low-power Bluetooth (BLE) products in a short period of time and don’t have to worry about
complex Bluetooth protocol application software. After the connection is established through the
serial port control, bidirectional data transmission can be realized between the BLE master and
the slave.
Function Overview:
1. Support pure pass-through mode and command mode: In pure pass-through mode, the data
received by the serial port will be transmitted to the host as it is, and the data received from the host,
it will be transmitted to the user MCU as it is. In command mode, the user MCU can configure and
obtain the parameters of the module through corresponding commands.
2. Can be switched between pure pass-through mode and command mode through IO port, and can
also be configured through the host;
3.Design of common serial port. The baud rate can be configured through the serial port or the host,
which makes it easy to adapt different MCU resources but the default is 9600bps, with low-power
data preservation;
4. The Bluetooth broadcast period and the Bluetooth connection interval can be configured through
the serial port or the Host, which is easy for reasonable control of Bluetooth power consumption
and low-power data preservation;
5. Configure the Bluetooth device name through the serial port or the Host to facilitate device
differentiation in actual applications and low-power data preservation.
6. The Bluetooth pairing code can be configured through the serial port or the host, and can be set
enabled or not;
7. Reset module through the serial port or the host
8. Factory reset can be restored through the serial port or the host;
9. The Bluetooth MAC address (physical address) of the module can be obtained through the serial
port.
10. The Bluetooth transmit power of the module can be set through the serial port or the host to
reasonably control the communication distance and the power consumption.
11. Support the simpliest development, that is, in the case of simple functional requirements, only
need to connect to the serial port for product development. For example, the mode control pin will
be kept in low level when no control is needed, saving the I/O resources of the MCU.

FCC Statement
This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to
operate the equipment.
FCC Radiation Exposure Statement
This modular complies with FCC RF radiation exposure limits set
forth for an uncontrolled environment. This transmitter must not be
co-located or operating in conjunction with any other antenna or
transmitter.
If the FCC identification number is not visible when the module is
installed inside another device, then the outside of the device into
which the module is installed must also display a label referring to
the enclosed module. This exterior label can use wording such as the
following: “Contains Transmitter Module FCC ID: N4Z-NB4 Or Contains
FCC ID: N4Z-NB4”
When the module is installed inside another device, the user manual
of the host must contain below warning statements;
1. This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including
interference that may cause undesired operation.
2. Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to
operate the equipment.
The devices must be installed and used in strict accordance with the
manufacturer's instructions as described in the user documentation
that comes with the product.
Any company of the host device which install this modular with limit
modular approval should perform the test of radiated emission
and spurious emission according to FCC part 15C : 15.247 and 15.209
requirement,Only if the test result comply with FCC part 15C :
15.247 and 15.209 requirement，then the host can be sold legally.
