5.1 Low power mode
In any case, Pin P06 input high enters sleep mode and reduces the whole power consumption. Now the serial port stops receiving
any data while the transparent transmission of the Bluetooth remains unaffected. In this mode the output function of the serial port is
still valid and data received in Bluetooth port can output via serial port.
Description:
1) If Bluetooth is connected, after entering the low power mode, you can command <BKTOSLPON>/<BKTOSLPOFF > to select
whether to disconnect the current connection. This function can be used to quickly disconnect the Bluetooth connection and enter the
low power mode after the external MCU is sent and received.

Copyright ©2012–2019, Chengdu Ebyte Electronic Technology Co.,Ltd. 5
2) When masters and slaves enter this mode, its scanning and broadcasting function remain unaffected.
5.2 Wake-up mode
In any case, WKP (P06) or serial RX pin (selectable command <COMWKPON> configuration to enable serial port wake-up)
input falling edge, the module wakes up from low power mode, if the command <WSMON> turns on mode feedback, wake up The
serial port will automatically output WAKEUP to notify the user that the wake-up operation is successful. From the detection of the
falling edge to the completion of the module wake-up for about 7 ms, the transparent transmission function is temporarily disabled
until the system wakes up successfully and the system returns to normal.
5.3 Configuration mode
In wake-up mode, the module enters configuration mode via pulling down Pin P00 and now any data received by the module is
regarded as configuration instructions rather than for transparent data transmission, that is, the transparent transmission function is
invalid.
Description:
1) Any data transmitted by the master via Bluetooth channel “CENTER DATA BUFF” is not for transparent transmission if
Bluetooth is connected now, and channel “BLE DATA BUFF” will receive feedback information “<CONFIG MODE BUSY>”to
indicate that the slave is in configuration mode and doesn’t receive data via transparent transmission.
2) In configuration mode, all configured information for the module will be saved after powering down and it will operate
according to the new configuration when powering up next time.
5.4 Data validity
Bluetooth outputs transparent transmission via serial port when receiving data. To ensure correct receiving of external MCU, at
10 ms before UART outputs the first start bit, P03 (APP) pulls down and wakes up external MCU till data transmission is completed
and P03 recovers a high level.. As shown in the figure:
Description: 1) The data output valid function can be commanded to turn on or off with <APPON>/<APPOFF>.
5.5 Role selection
The module can be configured as a master or a slave. In 160ms after powering up it starts to read the level signal of Pin P14. If a
low level signal is detected the module will be configured as the master; if a high level signal is detected it will be the slave; if the pin
floats, module with internal pull-up resistance will act as a slave. Role configuration is only valid when the module is powered up and

Copyright ©2012–2019, Chengdu Ebyte Electronic Technology Co.,Ltd. 6
initialized and the role is fixed after powering up is completed till next restart to redetect role configuration.
Description:
1) When operating as a master and with scanning started, the module will automatically scan surrounding slaves until valid
slaves are detected (If MAC address bonding is set, it is likely to connect to slaves with assigned MAC address) and the Bluetooth
connection is completed automatically.
2) When operating as a slave and with broadcasting started, the module will transmit broadcasting data packet to
surrounding areas via configured broadcasting gap and wait the Bluetooth master to initialize connection.
5.6 MAC address bonding
The module supports bonding of MAC address connected via Bluetooth, which bond connected MAC address via instruction
“ <BONDMAC> ” . When master sets bonded address, before a connection is completed, the master will firstly search that if address
of devices is compliant with bonded address, and only bonded devices can complete connection. Likewise, when slave sets bonded
address, before receiving request for connection from master it will search if MAC address of the master is the bonded address, and
when address is successfully matched the connection can be enabled or the salve will continue to broadcast. Carrying out instruction
“<DISBOND>” will stop MAC bonding. The slave can receive any request for connection from master when being stopped and the
master will connect to any slave devices in a valid area.
Description:
MAC address bonding can help to realize directional connection in complex conditions. For example, there are several slaves in a
valid scanning area for a master device. The master can filter requests for connection from salve devices to realize directional
connection.
5.7 Transparent continuous transmission
Slave supports transparent continuous transmission in which mode configured UART baud rate can be as high as 19200bps, i.e.,
no matter how large the data packet UART received is, or it is continuous data flow, transparent transmission remains unaffected.
Abnormal packet loss will not happen. This function realizes transparent transmission in a real sense.
Description:
After receiving the Bluetooth data, the slave module transmits the serial port transparently. Due to the “data valid indication”
function, the serial port delays the data output. Turning off the “data valid indication” can improve the data throughput speed.
5.8 Bluetooth packet length configuration
The module supports the long-packet standard of Bluetooth 4.2, and can command <MTU> to configure the length of the
Bluetooth single-packet packet. The default is 20 bytes, and the optional 20~128 bytes. The packet length can be increased to realize
the big-band data transmission of Bluetooth.
Description:
After the packet length is configured, it takes effect on the next Bluetooth connection.
5.9 UUID configuration
The module supports UUID flexible configuration, and can command <UUID128EN> to enable the 128-bit UUID function. The
command <SVRUUID>, <RXUUID>, <TXUUID> can be used to customize the transparent transmission service UUID, the reception
feature field UUID, and the transmission feature field UUID. This function can solve the problem that the UUID does not match the

Chengdu Ebyte Electronic Technology Co.,Ltd. E104-BT02 User Manual
Copyright ©2012–2019, Chengdu Ebyte Electronic Technology Co.,Ltd. 7
APP communication, meet more customization requirements, and is more practical.
5.10 Bluetooth sniffing
The module supports the Bluetooth sniffing function in the host state. In the host configuration mode, the command
<STARTSNIF> turns on the Bluetooth sniffing. The module automatically sniffs the surrounding Bluetooth broadcast data packet and
outputs the acquired Bluetooth information through the serial port. The output format is MAC (6 bytes) +RSSI (1 byte) a total of 7
bytes of hexadecimal data. (Special note: This function is valid in both master and slave modes, and it has nothing to do with whether
Bluetooth is connected or not. That is to say, the sniffing function is enabled in the Bluetooth connection state.)
Description:
1) The sniffing function is valid only in the Bluetooth host role and the configuration mode.
2) The broadcast packet sniffing speed can be configured by the command <SCANGAP>/<SCANWN>. The shorter the gap, the
larger the window and the faster the sniffing response.
5.11 Beacon data switchable
The slave module can be configured with "<ADVDATA>" and "<IBACON>" respectively, and the normal broadcast data and
Ibeacon broadcast data. After the broadcast is enabled, the module uses the configured broadcast gap as a fixed interval and broadcasts
3 ordinary broadcast data packets each time, switch broadcast 3 Ibeacon broadcast packets, and loop. This function realizes
synchronous transmission of ordinary broadcast and Ibeacon broadcast, which can achieve seamless connection effect.
In addition, the command <ADVSUST> can be configured as a broadcast non-switching function, that is, the ibeacon and the
normal beacon switch broadcast mechanism are turned off, and the broadcast mode is set to a fixed broadcast mode.
The default factory configuration enables Beacon data switching mode.

5.12 Air configuration
The module supports the air configuration function. After the Bluetooth connection is established in the slave state, the host can
access the "BLE DATA CONFIG" feature value under the transparent transmission service (FFF0). The configuration steps are as
follows:
1）、In the air configuration login authentication, send the command <PWDXXXXXX>, where XXXXXX is the login password,
the default is 123456, and return <OK> after success.
2）、The parameter configuration is executed, and the command is consistent with the serial port configuration command.
3）、Disconnect the Bluetooth connection.
Description：
1）、After the <PWDXXXXXX> command fails, the current login status will be exited immediately. That is, the configuration
operation needs to be resumed after the login is successful.。
2）、After the <RESTORE> command is executed, the login password is restored to the default settings.
6 Operating Instruction
