Network commissioning and diagnostics
We call the process of discovering and configuring devices in a network for operation, "network
commissioning." Devices include several device discovery and configuration features. In addition to
configuring devices, you must develop a strategy to place devices to ensure reliable routes. To
accommodate these requirements, modules include features to aid in placing devices, configuring
devices, and network diagnostics.
Local configuration
You can configure devices locally using serial commands in Transparent or API mode, or remotely
using remote API commands. Devices that are in API mode can send configuration commands to set
or read the configuration settings of any device in the network.
Remote configuration
When you do not have access to the device's serial port, you can use a separate device in API mode to
remotely configure it. To remotely configure devices, use the following steps.
Send a remote command
To send a remote command, populate the
Remote AT Command Request frame - 0x17
with:
1. The 64-bit address of the remote device.
2. The correct command options value.
3. Optionally, the command and parameter data.
4. If you want a command response, set the Frame ID field to a non-zero value.
The firmware only supports unicasts of remote commands. You cannot broadcast remote commands.
XCTU has a Frames Generator tool that can assist you with building and sending a remote AT frame;
see
in the
XCTU User Guide
.
Apply changes on remote devices
When you use remote commands to change the command parameter settings on a remote device,
you must apply the parameter changes or they do not take effect. For example, if you change the
BD
parameter, the actual serial interface rate does not change on the remote device until you apply the
changes. You can apply the changes using remote commands in one of three ways:
1. Set the apply changes option bit in the API frame.
2. Send an
AC
command to the remote device.
3. Send the
WR
command followed by the
FR
command to the remote device to save the changes
and reset the device.
Remote command response
If a local device sends a command request to a remote device, and the API frame ID is non-zero, the
remote device sends a remote command response transmission back to the local device.
When the local device receives a remote command response transmission, it sends a remote
command response API frame out its UART. The remote command response indicates:
1. The status of the command, which is either success or the reason for failure.
2. In the case of a command query, it includes the register value.
