The Tx power test determines if transmitter path can work normally with a specific power like 18dbm at 11b 11M rate. The RX sensitivity test determines if the receiver path can receive a relatively weak signal such as -85 db at 11b 11M rate.
We usually recommend that the customer use a certified partner module since the module partner themselves have already performed all the testing before releasing into the broad market. This Help Article was created to show a basic test procedure which allows the customer to determine if the issue encountered is on the RF hardware or software side.
Test machine Instructions :
MT8860C : 802.11b/g/a, 2.4G, 5G
MT8862A : IEEE802.11a/b/g/n/ac , 2.4G and 5G
IQ2010 : 802.11 a/b/g/n , 2.4G, 5G
IQxel : 802.11 a/b/g/n/ac , 11AC HT80 and HT160
I will use MT8860C with CYW43340WCD1-EVB to show the test process.
please also read the application notes from WICED studio in detail.
Sometimes you need to update mfgtest.bin or modify NVRAM for the test, please find them in above place. Test scripts already integrate some test command lists, you can take them as a reference , sometimes we need to change some items for a test like rate, channel .
test.mfg_test-BCM943340WCD1 download run
After application is download and run, please use below command to make sure wl tool and serial port run well.
If you meet this issue, it means serial port is occupied. Please disable the log UART com and input the command again.
Make sure you will see a WLTEST string in the output.
3. connect the board to MT8860C by RF cable .
4. Connect to MT8860C ，After scan complete, click Connect
5. Configure MT8860C into direct mode and the channel , rate needed.
The picture means 802.11g , channel 1 /2.4G, rate 54M, Direct mode
6. Set MT8860C attenuation.
Change the channel , and add the Path loss you assumed. We often set to 1db or 1.5db with RF cable connected.
7. Change the script to be compliant with MT8860C setting, please see the compare.
Please see the script, we often change comport, target WL tool, band , channel info, rate info.
if you meet test command problems , please raise case to us.
8. If we set the power into 14dbm, please see the results.
9. EVM results spec table.
You can get more from spec or Module maker, thanks.

Different countries has different WiFi regulations and it is user responsibility to meet those, if operating in a particular country. Setting Country code parameter in WICED STUDIO will help us to meet those regulatory standards.
By default in WICED the country code is set to "WICED_COUNTRY_UNITED_STATES". Please refer to the following file in WICED
If you are having problems with your installer, check that the download size of the installer is roughly 260MB, installer problems are typically caused by incomplete downloads.
The picture below shows a very common error message. Our SDK utilizes a 32-bit version of an Eclipse based IDE which requires a 32-bit version of JRE to be installed. If you already have the 64-bit JRE installed, you will also need to install the 32-bit version as well. The JRE is designed to allow both 32 and 64 bit variants to be installed on the system.
The WICED Sense kit uses a Silicon Labs USB to Serial Device. The TAG3 board uses an FTDI USB to Serial Device. Both should be installed as part of the SDK 2.2.1 installation process. If not, the FTDI drivers for the TAG3 reinstall them using the file /WICED-Smart-SDK/Drivers/dpinst.exe (make sure you access from the command line). The Silicon Labs USB Drivers can be foundWICED Sense Table of Contents
Everything we have for the WICED Sense, such as schematics, drivers, and Android application source code, can be accessed through theWICED Sense Table of Contents. A great post for the WICED Sense is theWICED SENSE Kit BLOGwhich is like a WICED Sense quick start guide.
Some Android devices appear to have issues pairing to the WICED Sense Tag from inside the app, linked is a work-around that should allow you to connect to your Android device:WICED Sense Android Pairing Work-Around
