BCM943602CS has working WiFi but not Bluetooth

[RehabMan]

This card is native ,am I right ？

Probably not bluetooth.

The patch is to add pid in iobluetooth,without patch,can not recognize BT,

Wrong approach.

BrcmPatchRAM2.kext + BrcmFirmwareRepo.kext , I don't find my card ID,so...

No idea if your bluetooth controller is supported by BrcmPatchRAM because your ioreg was corrupt.

Now the BT works fine after I installed BrcmPatchRAM2.kext + BrcmFirmwareRepo.kext and I add my product ID to BrcmPatchRAM2.kext

After all ,I'll check why my card is not naive, why others are true!

tks

As expected.
The iPhone does not pair, it uses BT4LE.

yes, got myself BT sound and its working perfectly

For the BT module from the BCM943602CS, identified as BCM2045A0 - 0x05AC 0x21FF, the dirty fix is to use another closer FW, to do this just edit the BrcmPatchRAM2.kext and add a key with :

<key>0a5c_21ff</key>
        <dict>
            <key>CFBundleIdentifier</key>
            <string>com.no-one.BrcmPatchRAM2</string>
            <key>DisplayName</key>
            <string>Broadcom BCM20702 Bluetooth 4.0 +HS USB Device</string>
            <key>FirmwareKey</key>
            <string>BCM20702A1_001.002.014.1443.1463_v5559</string>
            <key>IOClass</key>
            <string>BrcmPatchRAM2</string>
            <key>IOMatchCategory</key>
            <string>BrcmPatchRAM2</string>
            <key>IOProviderClass</key>
            <string>IOUSBHostDevice</string>
            <key>idProduct</key>
            <integer>8703</integer>
            <key>idVendor</key>
            <integer>2652</integer>
        </dict>

Clean the rest of the unused keys

In BrcmFirmwareRepo.kext just keep the BCM20702A1_001.002.014.1443.1463_v5559.zhx

And install both in S/L/E, reboot.

For me BT now work with handoff/continuity, i just have some lag if i try to listen music on a BT speaker.

Update : sound work like a charm, it was a faulty speaker device when i tried

*credit to derpuma (in my case i didn't touch the BroadcomBluetoothHostControllerUSBTransport.kext like he did)

I have the same card but it doesn't work... I also tried editing the BroadcomBluetoothHostControllerUSBTransport.kext but Bluetooth is still available but I can't deactivate it or connect/find any BT device.
I posted my logs here: https://www.tonymacx86.com/threads/bluetooth-not-working-on-bcm943602cs.241677/
