Figure 23: Read Non-volatile Configurations Command and Response
The response contains 55 bytes of configuration parameters. The full list of
parameters are shown in Figure 24 followed by descriptions of each one.
Note that this command reads out the configurations stored in non-volatile
memory. Any configurations that have been changed in volatile memory are
not read by this command.
Parameter 1 is the device type. This indicates whether the module is acting
as an Access Point (31), Range Extender (32) or End Device (33).
Parameters 2 through 4 are the module’s local address that uniquely
identifies it within the network. No other module in the same network can
have the same address.
Parameter 6 is the UART serial baud rate. The codes for this are shown in
Figure 25.
Parameter 7 configures the channel mapping for Frequency Agile mode.
This byte contains two parts. The high nibble defines the number of
channels out of the 4 available channels that are used. The low nibble is a
bitmap which defines which channel(s) are being used. In this nibble, bit 0
corresponds to channel 0, bit 1 to channel 1 and so forth.
For example, the factory default value is 0x12. The high nibble is 0x01, so
one channel is being used. The low nibble is 0x2, which is binary 0b0010,
so channel 1 is being used.
