Regulatory and Certification Information
Regulatory certification/tests were done using:
•
SDK version 2.2
•
Bluetooth version 1.2.X
•
IEEE 802.15.4 version 5.3.X
The RF synthesizer within the PAN4620 can be configured to use any channel
frequency between
2.36 GHz and 2.487 GHz. The information given in
6 Regulatory and Certification Information
is only valid within the ISM
frequency band
starting at 2.4 GHz. We recommend to use the certified
Bluetooth LE, Thread, and Zigbee wireless stacks provided by NXP, to not
void all pre-certifications and to be sure you are comply with regulatory
requirements.
6.1 Federal Communications Commission (FCC) for US
To comply with FCC regulatory requirements, it is necessary to reduce the
output power from 3.5 dBm to about 0 dBm on the highest 802.15.4 channel
(channel 26 at 2
480 MHz).
It is necessary to do this in the software of the end product and in the tool
used during certification testing. The following example shows how to adjust
this setting in the example code, which we recommend for certification testing.
This example is included in the NXP SDK.
Reducing output power in the software
1. Open the example project with the designation
frdmkw41z_wireless_examples_smac_connectivity_test_freertos
.
2. Go into the folder
source
and open the file
connectivity_test_platform.c
.
3. Go to the function
ShortCutsParser
in line 164 and replace the code in case
q
,
w
,
a
,
and case
s
with the following code:
case
'q'
:
if
(testChannel == (
channels_t
)gTotalChannels)
{
testChannel = gChannel11_c;
}
else
{
test+;
}
