Currently I am in certification process with our product using the AMW007 WiFi module and the proposed PCB antenna. I need the module to continuously transmitt modulated 802.11n signal. I followed the instruction on "Zentri Classic/Legacy Module Setup for Certification Testing" page and established a connection to the AMW007 module via ATG002 (Piranha) Board. So fare everything seems to work. I am able to boot the AMW007 in programming mode; I can run wl_gui.exe and program the AMW007 with "RF" application; I can configure "TX Radiated" test parameters and start/stop the test.
However, the AMW007 does not transmitt anything (verified with Metageek WiSpy DBx). I tested with two different devices, both did not transmitt. Below I attached the serial log. Could someone help me to get this running?
Boot in programming mode log:
ets Jan 8 2013,rst cause:2, boot mode:(1,7)
Boot mode is indicated as (1,7) but in the Certification Testing documentation (1,6) is depicted. Is this an issue?

I used the following parameters for TX Radiated test: Channel 9, Rate MCS0, Tx Power 14 dBm
In Addition I tested with the AMW007-E03 (Medusa) Eval Board to have identical setup as described on "Zentri Classic/Legacy Module Setup for Certification Testing" page. The start-up code is identical with the description (i.e. mode: (1,6)).

However, there is no emission when starting the "TX Radiated" test. With the Metageek WiSpy DBx I measure the company WiFi and some BT beacons but no signal at the configured test channels.
I was able to fix the problem. The antivirus application on my computer blocked the execution of some files. I had to declare the complete "WiFi" folder as an exception in the antivirus program. Now the AMW007-E03 (Medusa) Eval Board and our custom board with embedded AMW007 transmits as intended.
