Hi ,

  Greetings 🙂

  We are developing HomeKit compliant product and planning to WICED with STM32. For the same, our hardware supplier is recommending BCM43438. But based on the community mailing list, we realize that this is not a mass market supported Broadcom. [Bcm43438, which version of WICED sdk can use ? ]

   Hence, was interested in knowing whether BCM4343W can be considered as replacement for BCM43438.

   Please let us know.

Thanks in advance,

Best regards,
Gupta

I moved this to the WICED Wi-Fi forums.

The BCM4343W and BCM43438 are packaging options for the same chip.

The BCM43438 is an SoC based design, so it is not supported here on the community and there is not an associated dev kit.

It's depends.

The latest SDK supports both BCM4343W and BCM43438 as platforms as you know.

So if your supplier provides 43438 based module, you can use it I think.

Of course BCM4343W can be used instead of BCM43438(WLAN+Bluetooth).

By the way, only fewer people check messages in this group,

so I recommend to post your question to WICED Wi-Fi Forums (not to Homekit group).

Which STM32 is your hardware vendor recommending? Most STM32 don't have enough SRAM to run homekit.

Hi nsankar

  We are planning to use STM32F405. It has 192Kbytes of SRAM.

  What is the minimum requirement for homekit?

Thanks and regards,

Gupta
