in my experience, these chips get WiFi but no Bluetooth. (not new like the listing suggest) one looked new the rest didn’t. but I reballed them all anyway.
I had a total of 5 switchs I did this weekend. (mostly V2s.
I installed the chip from this seller. (I ordered the cym ones but they sent the broadcom ones.
when installing these chips I failed to get Bluetooth. so I pulled the WiFi chips off other PCBs I have (didn’t check which version. and both Bluetooth and WiFi worked fine first time
I repeated this 5 times in a row pretty much and got the same results. so I don’t personally believe it’s my method. as everytime reballed one I pulled off a board myself it always works on the same switch I had problems with these chips.
