Switch Wifi IC Replacement Help

[Kill-Switch]

I need your help, I unsoldered the Wifi IC (CYW4356) on my switch.

Now I need another one.

1.Can I also take the CYW4356 or BCM4356.

2. If I buy a new one, it will be programmed. How and where do I get the software. A TL866 is available.

3. Or order a used one via Alieexpress.

4. Where can you order good ones?

It's a bit confusing - one says you can use both chips, another says the chips are programmed.

Some good information would be great.

Sorry for my English is Google Translate.

No you need the same model, they are not cross compatible.
Yes new chips need to be programmed, although i've never used new chips so not sure how to do it. Just get a used one, I bought 10 chips from aliexpress and they work every time
