WGM160P module is pre-certified for CE, FCC, ISED, KC South Korea, and Japan. For more information, please see:

If you are trying to re-certify the module, or the end product using Gecko OS, please have a look at the certification example app found in the SDK at ~\applications\gecko_os\test\certification. The purpose of this example is to provide the functionality needed for certification.  Like all example apps you can clone it from Gecko OS studio.  It is found under "Test Examples" as shown below:

Note: the test app referred below is based on Gecko OS 4.1.11

Please see below for the different variables and settings:

There is also a custom command to start the transmission or reception of frames: wifi_test start

Examples:

Get TX_PACKET 11n MCS7 continuously to RF2 output (test in conducted):

set wlan.antenna.select 2
set wifi_test.channel 6
set wifi_test.mode tx_packet
set wifi_test.period 5000
set wifi_test.tx.protocol n
set wifi_test.tx.rate 7
set wifi_test.tx.ht_format mm
set wifi_test.tx.length 1400
set wifi_test.tx.number 0
wifi_test start

TX_PACKET 11g 54Mbps:

set wlan.antenna.select 2
set wifi_test.channel 6
set wifi_test.mode tx_packet
set wifi_test.period 5000
set wifi_test.tx.protocol g
set wifi_test.tx.rate 54
set wifi_test.tx.length 1400
set wifi_test.tx.number 0
wifi_test start

DSSS 11b 11Mbps

set wlan.antenna.select 2
set wifi_test.channel 6
set wifi_test.mode tx_packet
set wifi_test.tx.protocol b
set wifi_test.period 5000
set wifi_test.tx.rate 11
set wifi_test.tx.length 1000
set wifi_test.tx.number 0
wifi_test start

Stop TX after 100 frames and update the TX for rate MCS4 (if already in 11n):

set wifi_test.mode tx_packet
set wifi_test.tx.number 100
wifi_test start

TX stopped. Set tx.rate in MCS4 and then TX frames continuously

set wifi_test.tx.rate 4
set wifi_test.tx.number 0
wifi_test start

Get CW signal to RF2 output:

set wlan.antenna.select 2
set wifi_test.channel 6
set wifi_test.mode tx_cw
set wifi_test.period 5000
wifi_test start

WLAN backoff of 5dB on channel 6 for mod_group_5

set wlan.backoff 6 0,0,0,0,0,5

RX_PACKET for 11bgn 20MHz signals on channel 7 on RF2

set wlan.antenna.select 2
set wifi_test.channel 7
set wifi_test.mode rx
set wifi_test.period 5000
wifi_test start

We get then every 5 seconds (wifi_test.period=5000µs) this Rx statistic report:

The statistics are done on 5 seconds. In this example, the Wi-Fi source transmits only 802.11n MCS7 frames in the channel 7.

Please note when some packets are completely erroneous and not detected like a Wi-Fi frame then they are not counted in “Frames received” or “Bad Frames”.

This PER accuracy issue, it happens more when we are close or below the sensitivity level.

So in order to get an accurate PER, you have to compute it based on number of transmitted frames by the Wi-Fi source.

To stop this Rx mode with statistic report:

set wifi_test.mode tx_packet
set wifi_test.tx.number 100
wifi_test start
