Note
The data length of this message encodes the number of frequencies to
populate into the hop table. The length must be divisible by four for the
message to be properly formatted.
This example shows a command that sets up a table with only three values:
The generated hop table has values of 902MHz, 915MHz, and 927.25MHz. For the US
region, valid frequencies are 902MHz – 928MHz. If any of the values in the table are
invalid, then none of the values are recorded.
The Set Frequency Hop Table command should be used for debug only, as there
should be no reason to modify the frequency hop table in the field.
Set User GPIO Outputs (96h)
There are two GPIO outputs available for use. The Set User GPIO Outputs command
has been “overloaded” to create a mechanism to return the current state of both GPIO
pins. To set either GPIO Output pin, send the following command. Note that the data
length is 2 bytes:
FF 0C 95 00 0D C3 70 00 0D F6 38 00 0E 26 12 C1 8F

CAUTION!

Any changes to the frequency hop table
could put you out of compliance with the
Local Regulatory Requirements (for exam-
ple, FCC, ETSI, MIC).
