Summary:
The difference between Signal mode and Direct mode is: we only need to connect the EVB with the test AP created by AP, then AP will have a menu to test TX and RX related. Its aim is to figure out if the actual running power is matching what you want, RX path has no RF de-sense in a normal running mode. If signal mode passed all the RF standard, we can have a confidence that current RF path include TX and RX, current RF configuration like NVRAM have no critical issues. We can move the product into next long-run function tests.
- Which EVB is for the tests?
I choose 43340 because it has 2.4G and 5G together.
- How to set 8860C before test.
1. Set the static IP address
2. configuration .
Which means creating a AP at 153 channel with 6M rate and power is -15dbm.
After AP created we use command to join the AP, then we can do the test .
- Which application is needed for the tests?
I used the command console for the test because we can use a lot of embedded commands to join a specific AP and do some command input.
And we are using the normal firmware for the test, please see the command output.
test.console-BCM943340WCD1 download run
- Which commands are needed before the tests?
After connection established “scan_suppress 1” , “roam_disable ” are preferred .
PM = 0 is good to be set also.
In command console:
Usage: scan_disable <1 = disable scan|0 = enable scan>
> scan_disable 1
If you didn’t have this command, please add it according another blog.
- How to change country for a test ?
Please input “set country ”, then get channel , choose one channel to do connection with the AP created by instrument.
> get_country
Country is US (US/0)
> set_country CN/0
> get_country
Country is CN (CN/0)
> get_channels
