Hi,

Noticed that there are 2 Android releases:

Android release based on brcmfmac: Cypress Android 10 Release [2021-01-14] - Infineon Developer Community

Android release based on AHD/bcmdhd: Infineon Android Release [2021-06-29] - Infineon Developer Community

 

My question is why two releases for Android? What's the difference? What AHD stands for?

 

Thanks,

The 2021-01-14 release is based on the open source Linux driver, which has legacy chip (43455...etc.) support up to Android 10.

AHD (Android Host Driver) was created for newer Android version and newer chipset support like : 54591/4373/43012.

The difference is essentially between FMAC and DHD driver. It is summarized in this community thread https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/Which-driver-bcmdhd-or-brcmfmac/m-p/1270...

AHD stands for Android Host Driver. We moved from FMAC to DHD driver for Android. We will check for the reasons and differences and let you know
