For some MCU works at 5V DC, it may need to add 4-10K pull-up resistor for the TXD & AUX pin.
6.1 AUX description
It can indicate whether there are data that are not to be sent via wireless yet, or whether all wireless data has been sent
through UART, or whether the module is still in the process of self-check initialization.
No.
Description

【Indication of UART output】can be used to wake up external MCU.
(Note: AUX indication has no delay in continuous transmission mode)
2
【Indication of wireless transmitting】
1.The length of the buffer in the module is 512 bytes, and the single packet must not exceed 128 bytes,
when AUX=1, users can transmit data continuously within 128 bytes.
2.When AUX = 1, it means that all the UART data of the module have been transmitted wirelessly.

6.2 LINK description
The LINK pin indicates the current network status, after the node is connected to the network, the current pin is
pulled low. The external device can query the device network status through the pin level. In the coordinator mode,
the pin indicates if the module establishes the network normally.
6.3 ACK description
The ACK pin is used to indicate the status of the last user’s data transmission. Before transmitting, the pin is pulled
low. After the transmission is successful, the pin is pulled high. The user can use this pin state to judge if the data
has arrived successfully. This pin function cannot indicate the coordinator to send broadcast message.
Note: When 200 nodes sending data at the same time, the device will use the CSMA/MA technology to access the
channel before sending data. When the receiving device receives the data, the returned ACK does not have this
mechanism. In extreme conditions, it means that even if the receiving device receive data normally, ACK pin of
sending device will still indicate that the last data transmission failed.

7.1.Coordinator mode
If the user configures the operating mode 4 (namely AT+ WMCFG =4, refer to Chapter 9),（M0=0,M1=0）or the user
configures the operating mode as 0 (namely AT+ WMCFG =0), the module works in the coordinator mode. In the
coordinator mode, the coordinator can set up the network, coordinator is the central node of the network, there must be a
coordinator in the network.
The coordinator configurable data input mode is:
Broadcast transmission, When configured to broadcast, all non-dormant devices on the entire network will receive data.
The ACK pin unconditionally indicates successful transmission.
Short address transmission, when configured to short address transmission, the user must specify the short address of the
receivind device before sending data.
Long address transmission. When configured to long address transmission, the user must specify the long address of the
receiving address before sending data.
7.2.Normal node
If the user configures the operating mode 4 (namely AT+ WMCFG =4, refer to Chapter 9), （M0=0,M1=1）or the user
configures the operating mode as 1 (namely AT+ WMCFG =1), the module works in the normal node mode. In the normal
node mode, the data can be received and sent in real time. It is suitable for application with request of high real-time
response and no request of low power consumption.
7.3.Dormant node
If the user configures the operating mode as 4 (namely AT+ WMCFG =4, refer to Chapter 9),, M0=1,M1=0, or the user
configures the operating mode as 2 (namely AT+ WMCFG =2), the module works in the dormant node mode. In this mode,
the device request if there is data transmitted by coordinator according to the user-configured sleep period , The
non-broadcast data sent by the coordinator will be temporarily stored inside the coordinator. The device is in low power
consumption during the sleep period. If the dormant node wants to send data actively, the user should send a data within
two bytes to wake up the device. After the wake-up data is sent, the user needs to wait for more than 100ms to send the
real data. And the wake-up data will be discarded. After the device was waken up, the module will open the serial port to
receive AT command, if there is no data input within 2 seconds, the module will close serial port and go to sleep.The

dormant node is suitable for applications where the user requires low power consumption and does not require high
real-time response..
7.4 Configuration mode
At any time and in any mode, as long as the M0M1 combination is set to 11, the system will switch to the
configuration mode. In the this mode, the serial port parameters are: 115200, 8N1, and the average operating current is
2uA.
In this mode, the module cannot send or receive data. When using the external AT command to configure the
module, the user serial port need to send any data within two bytes to wake up the device. After the wake-up byte is sent,
the user needs to wait for 100ms to send the real data and the wake-up data will be discarded. After the device was waken
up, the module will open the serial port, receiving AT command, if there is no data input within 2 seconds, the module
will close serial port and go to sleep. To use the next AT command, user need to resend a wake-up byte.
7.5 Mode switching
No
Remarks
1
In default, The user can decide the operating mode by changing the combination of M1 and M0
2
In any work mode, the user can configure the operating mode through the AT command ( refer to Chapter 9)

(reboot valid)
AT+RSCFG=?
Description:
Gets the auto restart parameter settings
Response：
RSCFG:0
AT+RSCFG=Value
Description:
Value：0 or 60~65535（S）

AT+CLINFO Clearing network information of the module
AT+CLINFO
Description:
Example：AT+CLINFO
Note: The module cannot communicate after clearing the network. It needs to re-establish the network for communication. (thiscomman allows
the user to clear all information when the number of node devices connected to the coordinator reaches 200.)
21
AT+TLCFG Setting/Querying the concurrency performance parameter (restart to take effect)
AT+TLCFG=？
Description:
Gets the concurrency performance parameter
Response：
TLCFG:0
AT+TLCFG=value
Description:
Value:0~3
0：Low concurrency
1：Medium concurrency
2：High concurrency
3：Highest concurrency
Example: AT+ TLCFG =0
(Note: This parameter is mainly used to configure the concurrency performance of the module. That is, when various nodes concurrently
transmit data, the maximum number of nodes is supported. The higher the performance, the greater the number of concurrent systems, but the
delay in sending data and the average power consumption of the nodes will increase; the lower the performance, the higher the real-time
performance of the data sent by the nodes, but the data may be lost when the environment has large interference or multiple nodes transmit
simultaneously.)
