FAQ
[Failed to access the network]: Please check if the node PANID setting is consistent with the coordinator when the nodes
are unable to access the network
[Garbled]: One reason is that the serial baud rate does not match. The o ther reason is that the power supply capacity is
insufficient.
[High delay]: When the node sends data, if the current channel noise is too cloud, it will actively back off. After waiting
for a period, the node will idle and start sending.
[Receive response time]: When the node is configured as dormant node, the maximu m receiving delay may be equal to the
configured period
[Unable to communicate]: The modem must be connected to the network to communicate with the coordinator
[Unable to read parameter]: Check whether the baud rate of the serial port is correct. You can query in the configuration
mode.
[Into the network is too long]: During the network access process, the node and the coordinator have a large number of
information exchanges. This process does not have any protection mechanism and the information is easily interfered. After
a node fails to access the network for a single time, it will request again after a certain period of time.

Firmware Transmitting mode
5.1.
Transparent transmission
Format
Values
When the coordinator is set to transparent transmission, the coordinator will send broadcast message. At this time, all non-dormant
nodes in the entire network will receive data.
5.2.
Short address transmission
