AT+ClcNoNet
Clearing the internal network information
AT+ClcNoNet
Description:
Example
：
AT+ClcNoNet
Note: The network cannot be re-established after the module is cleared ( This instruction can clear all the information when
the coordinator node number reaches 50)
8. Note
⚫
In sleep mode, The serial port parameters are 115200, 8N1( fixed). If the user forget the current baud rate, they can use
this At command to reconfigure.
⚫
After the node is associated with the coordinator, the node information will be saved, and the information will still
exist after the node is disconnected from the network, this mechanism has two advantages:
1.When the same node joins the network established by the coordinator, the network access speed will be increased.
2.After a node enters the network, the short address will never change as long as the current network exists.
If the coordinator has associated more than 200 devices and wants to continue associating new devices, you need to call
the AT+CLINFO command to clear the current network information.
⚫
The average power consumption of low power nodes depends on the wake up period of user configuration. The larger
the cycle, the lower the power consumption, but the delay of receiving coordinator will be even higher.
⚫
Low-power node cannot receive broadcast data which transmitted by the coordinator
⚫
The system will be reset if the node is powered on for more than 60 seconds and it has not yet entered the network.
⚫
When node PANID is set to 0Xffff (65535), the node can join any network, otherwise it will only be able to join the
same network as its PANID.
