4. Function
4.1 Roles
There are three roles: master, slave, and observer.
The master module connects to other Ebyte Bluetooth models. Up to 4 slaves can be connected to it. Transparent advertising and
format transmission are available. Both manual and automatic connection are allowed.
The slave module connects to other Ebyte Bluetooth models, only one connection is allowed. Only transparent transmission is
available for slave.
The observer is only used to print information about the ble device around the module and cannot be connected.
4.1.1 Master
1. AT+ROLE=1 choose role as master;
2. AT+SCAN=1 master scanning started;
3. AT+AUTOCONN configure if it is automatically connected after power on；
4. Once in manual connection，AT+CONN configure to connect specific device；
5. One master and multiple slave connection is available. Maximum connected slave quantity is 4;
3引脚内部电平自锁存。为电平时，内部上拉，为低电平，内部下拉。

6. Print status information when the master connection status changes. See 6.3 for Status Print.
4.1.1.1 Master connecting method
4.1.1.1.1 Condition filtering
The device can be configured to filter by MAC address bonding and service UUID.
UUID filtering is filtered according to the content configured by AT+UUIDSVR. The filtering condition cannot be closed. If
MAC address filtering is not enabled, the MAC matches, it is automatically connected to the slave once service UUID is matched.
If the user needs MAC address filtering, MAC address filtering needs to be enabled through AT+BOND=1, and the MAC address
is added to the master through AT+BONDMAC. After the master scans to the slave, if it is the same as the binding list MAC address
and the service UUID, it automatically connects to the slave device.
If the master is configured as a manual connection, MAC address binding filtering will be ignored, but svruuid is consistent.
4.1.1.1.2 Automatic connection
If configured to connect automatically, the slave is automatically connected after the condition filter is met.
If configured to connect manually, turn on scanning. The master will scan the device with the service UUID matched and output
through the UART (the data format is as shown in Figure below, the master outputs the scan result data format). The user connects to
the specified slave device using AT+CONN.

4.1.2 Slave
1. AT+ROLE=0 choose role as slave.
2. AT+ADV=1 configure normal advertising mode.
3. The broadcast switch is configured to be enabled. Once power on, it automatically enters the broadcast state. Otherwise,
the broadcast device cannot be found.
4. After receiving the master connection request, establish a Bluetooth connection to stop the Bluetooth broadcast and enter
the data transparent transmission mode.
5. Check 5.5 for advertising configuration.
4.1.3 Observer
1. AT+ROLE=2 choose role as observer（Reset to be valid）.
2. After receiving the broadcast, print out the entire contents of the broadcast package through the serial port.
3. It cannot connect any device.

4.2 Power mode
There are two modes：low power mode and wake-up mode.
4.2.1 Low power mode
The low power mode means that the BLE function continues to run after entering this mode, and the peripherals except the
wake-up pin are turned off. If you need lower power consumption, you can turn off the broadcast, scan, disconnect all connections, set
a longer broadcast gap, scan the gap, and connect the gap by AT command.
Enter low power mode：
1. AT command “AT+SLEEP”: enter low power mode；
2. AT command “AT+DISCSLEEP=1”: disconnect and enter low power mode；
3. AT command “AT+ONSLEEP=1” : enter low power mode once power on；
4. Via pin WKP rising edge，keep high level for 200ms and enter low power mode；
To output “STA：sleep” via serial port after entering low power mode（LOGMSG output unclosed）。
Note: In low power mode, when it is not disconnected, for example, when ble receives data over air, or when the connection
status changes, the module temporarily wakes up and outputs the corresponding data, and immediately goes to sleep after the data
output is completed. At this point, entering low power consumption, or waking up will not output status data.
4.2.2 Wake up mode
In this mode, the peripherals of ble modules works normally. Once it waked up, it outputs “STA：wakeup”.
Wake up mode：
1. Via pin WKP falling edge，keep low level for 200ms and enter wake up mode；
2. Pin RX wakes up, via falling edge of pin RX，keep low level for at least 50us and wake up immediately。
4.3 Data transmission mode
There are two transmission mode：transparent transmission and format transmission.
4.3.1 Transparent transmission
It refers to the data received by the serial port is sent to the other device through BLE without any processing, and the data
received by the BLE is sent through the serial port without any processing.
In slave mode, only data transparent transmission is available. The result of the command "AT+TRANMD" is invalid for the slave.
In master mode, data transparent transmission is sent to each connected slave module by advertising. Due to the use of broadcast
transmission, under extreme conditions, there is no guarantee that each slave will be able to receive data. The host is set to the
transparent transmission mode by the instruction "AT+TRANMD=1".
4.3.2 Format transmission
The data sent to the module through the serial port and the data transmitted through the serial port must be in accordance with the
defined format and transmitted. It should be noted that the format transmission of the module also supports the transmission of data in
a broadcast manner.

It is unavailable for salves.
Send to slaves command “AT+TRANMD=0” to switch it to format mode. Format is as follows：
Slave ID
Valid data
1byte
Max:243bytes
0~3/0xff
Salve ID：0~3. It is printed by master from “STA:connect,1<mac>” after mster and When slave ID is 0xff, every device is
under advertising.
Every packet output via uart is format transmission.
If connection defined by slave ID doesn’t exist, module will abandon this packet directly.
4.4 MAC address bonding
To enable MAC address bonding, the device connects only to devices with MAC added.
4.5 Advertising

4.6 Configuration
There are two configuration modes: serial port configuration and air configuration. They are basically the same. Before the air
configuration, the authentication password AT+AUTH=123456 must be passed. Once it is passed, the module is allowed to use the air
configuration. The authentication period is the current connection. When disconnected and reconnected, it needs to be re-authenticated.
The module is in configuration mode before the connection is established. The Mod pin is invalid.
After the connection is successful, it is determined whether the module is currently in the configuration mode or the data
transmission mode according to the mod pin level. When mod is high, it is the data transfer mode, and when it is low, it is the
configuration mode.
The Mod pin latches the current state when a valid change is detected. Each state change hold time is valid for at least 200ms.
The Mod pin has no effect on the air configuration.
In configuration mode, the mster sends data to “MAST CHANNEL” and the slave returns “CONFIG BUSY” via “SLAVE
CHANNEL”.
4.7 Data indication
When data is output through the serial port, the DATA pin is set to low level, indicating that data is being transmitted. The AT
command response does not change the state of the DATA pin.
Data output delay is enabled via with AT+DATALY=1. After it is turned on, the module first pulls the DATA pin and outputs the
data after 10ms.
Data output delay
No delay of data output
