@ZombieBest I experienced the same issue with the DW1830 as you did. Thought the issue was with my card and replaced it with another DW1830 and had the same issue. One thing I found was that if I just had Bluetooth on with no devices connected, BT would not dropHello,
I have High Sierra 10.13.3 on my Dell XPS 13 9350. I have the DW1830 Wifi Card with BCM2045 Bluetooth.
After Sleep Bluetooth works for about 2-3 minutes then, if no device is attached it get's "disconnected" (in ioreg device disappears).

If a device is attached right after sleep, then Bluetooth works with no issue, but the same problem appears after 2-3 minutes the device disconnects.
If I have Apple AirPods connected, while the earphones are still in my ear, BT works (even if no audio is played). If I remove a headphone, and no sound is played in the other, BT probably goes into low-power state and after 2-3 minutes it's not available. A sleep-power cycle fixes it, but the problem is the same.
So, I assume issue is related to low power BT state. I attach a ioreg with the Bluetooth still working (connected on USB HS03) and everything needed from Problem Reporting. If you need something else let me know!
Also, for reference, in this Thread they are discussing about it too (on XPS 9360): https://www.tonymacx86.com/threads/guide-dell-xps-13-9360-on-macos-sierra-10-12-x-lts-long-term-support-guide.213141/
Shouldn't you use BrcmFirmwareRepo instead of BcrmFirmwareData?On my Lenovo Thinkpad x250 I have the same problem: Bluetooth works fine when AC is attached, but without AC on battery no Bluetooth hardware is available.

@Gymnae try putting BrcmRepoData in /L/E/ instead of BrcmFirmware Data. My BT does drop out in my XPS 9560. However, it turns "back on" if I close the lid, causing it to sleep, then opening it a few mins later. I know this is not a solution. But, hopefully, it will be a step in the direction of figuring out how to resolve this once and for all.On my Lenovo Thinkpad x250 I have the same problem: Bluetooth works fine when AC is attached, but without AC on battery no Bluetooth hardware is available.
