According to CHANGELOG.txt, Changes for WICED-SDK 3.4.0: Added support for BCM4343W WLAN device.
Thank you for your information. You are right. I checked the SDK 3.4.0-AWS on web sight.
Just curious, why are you looking for the oldest SDK but not latest SDK?
Some customers module needs newer FW than version 184.108.40.206. I must investigate all WICED version is newer than this or not.
I checked FW version of SDK 3.4.0-AWS was 220.127.116.11. If you know the difference between these two vesion, please let me know.
