4. Operation modes
4.1 Low Power Mode
Low-power mode: The module enters the low-power mode at once by AT command “AT+SLEEP”, or enter the
low-power mode after disconnecting the “AT+DISCSLEEP=1”setting, the serial port output “STA ：sleep”when the
command enters the low-power mode at once, if the broadcast function module is not turned off, the broadcast gap as the
wake-up time will broadcast. See 6.37 Get to sleep mode at once
Description：
1. If broadcasting is turned on in low power mode, the host can scan the broadcast and establish a connection with the
module, and the module wakes up at once after the connection is established.
2. The module enter low-power mode to support serial data wake-up (the first frame data will be lost as wake-up
source data).

4.2 Wake-Up mode
WKP pin: When the module enters the low power mode, the user can pull down the wake-up via WKP pin.
Serial port wake-up: When the module enters the low-power mode, any data received by the serial port will wake up
the module. The frame data module does not operate on it. At this time, the serial port outputs "STA: wakeup".
In wake-up mode, the module can broadcast, can enter configuration mode, can be scanned and connected. If the
main device is connected to the module, the serial port output "STA: connect", the module can transmit data transparently,
after the device is disconnected, the serial port output "STA: disconnect".
4.3 Configuration mode
Configuration mode: AT command can be operated by default when the module is powered on (See 6. Instruction
operation ). If the MOD pin is pulled down in connection state, the module will also enter the configuration mode.
Description: Bluetooth communication is interrupted in configuration mode, data cannot be sent or received.
4.4 Data valid indication
In the transparent transmission mode, the user can set the delayed output data by “AT++DATDLY=1” command.
After the delay output is set, the DATA_LINK pin of the module will output low level 10ms before the data is sent, so as
to wake up the external MCU. After 10 ms, the data will be sent, and the DATA_LINK pin is pulled high after the data
transmission is completed. As shown in the figure:
4.5 IO level reading
The user can request the specified IO pin level by AT command AT+IO0?" or "AT+IO1?"(See 6.39 Read IO0 inpu and 6.40
Read IO1 input)
4.6 IO output
The user can request IO2 output level by AT command "AT+IO2=1" or "AT+IO2=0"
(See 6.41 Set IO2 output and 6.42 Set IO3 output).

4.7 PWM output
The user can set the PWM cycle by AT command "AT + PWMFRQ = xx" and set the PWM0 duty cycle by AT
command "AT + PWM0 = xx".
See more details about PWM setting (6.43 Read/Set PWM0 duty cycle, PWM output cycle setting 6.47 Request/Set
PWM output cycle
PWM output example as following:
4.8 MAC address bonding
When E104-BT05 sets the binding connection address, opens the binding enable, retrieves whether the host MAC
address is a binding address before accepting the host connection request, the connection is established if the address
matches successfully, otherwise, the slave will continue to broadcast.
See more details: 6.23 Read MAC binding status, turn MAC binding on and off.
4.9 Bluetooth single packet byte length MTU Configuration
The user can configure the maximum single-packet data length by AT command "AT+MTU=xx". The default is 20
bytes, and 20~128 bytes is optional. The packet length can be increased to realize the big packet data transmission.
Description: The next Bluetooth connection will take effect after the packet length is configured.

4.10 UUID configuration
The module supports UUID flexible configuration. It can turn on 128-bit UUID function by command "AT +
UUIDTYPE = 1" , and customize the transparent transmission service UUID, receiving feature field UUID, sending
feature field UUID by command "AT+ +UUIDSVR=xx", UUIDCHAR1 = xx", "AT + UUIDCHAR2 = xx"
See more details from 6.26 Request/Set transparent transmission service UUID length ,
4.11 Broadcast data switchable
The E104-BT05 supports general broadcasting and iBeacon broadcast. The command can be configured to select the
broadcast mode. (Note: Since the default MTU length is 20 bytes, if the data length is longer than 20 bytes when setting
the broadcast data, the user needs to modify the MTU length before setting broadcasting data.
General Broadcast packet format:
The broadcast information includes advertising and scan response, advertising is the active broadcast, and scan
response is a broadcast report that is replied after receiving a host scan request.

4.12 Configuration over air
The air configuration refers to the terminal device (such as mobile phone, tablet, etc.) that supports the BLE
function, and reading and writing module parameters through wireless mode.The configuration process uses the FFF3
feature value of the FFF0 service to implement the instruction transceiving. Its attribute is read/write/notification, and the

Chengdu Ebyte Electronic Technology Co., Ltd E104-BT05 User Manual

11
configuration instructions refer to Chapter 6 Instruction operation. The air configuration can realize all parameter
configuration operations of the module, including special IO read/write commands and PWM output control.
Air configuration method:
1. After the connection is established, the terminal device sends an AT command to the FFF3 feature value under the
FFF0 service
2. "Air Configuration" requires password authentication. Send authentication information by command
"AT+AUTH=xxx", after the authentication is successful, the configuration status can be entered.
3. The authentication is successful until the connection is disconnected.
4. MOD pin has no effect on the air configuration process
5. See more details for air configuration operation instructions, see 6.33 Request/Authenticate Air configuration
password and 8.2 Transport transmission and Air configuration mode.

5. Instruction operation
Note: Before sending operation instructions, first ensure that the module is in wake-up mode, otherwise it will not be
able to receive configuration instructions.
