16-inch MacBook Pro Bluetooth issue

Yes no problem

The adapter im using is

plus it has a CSR8510 Chipset like @vitorhenrique

Simply a joke and not a reason for me not to plug such a device in...

within 3 fixed here in germany they have to take the device back!

Never heard such problems - not to plug in a specific usb adapter LOL

How could any noobie know this? Simply not possible...

I had my bluetooth adapter connected on the side of Sennheiser SDW-5000 which then connected to the CalDigit hub via USB.

I just had the laptop returned from Apple. Never connecting a bluetooth adapter again till hear otherwise from Apple.

I saw Catalina got 10.15.4 update today, and didn't see anything about Bluetooth on the release notes.

I can also confirm that this is the case.

I share a monitor with my stationary computer. I recently got my self a bluetooth dongle to use with my home computer, its plugged in to the dell monitor and after i connected my mac to it. I haven't been able to connect any bluetooth devices back onto the MacBook 2019 16" using the internal bluetooth.

Im not very tempted to deliver my computer in for repair in these corona times :P

Hope it's possible to patch this problem somehow. I cant understand how a dongle is suppose to destroy the internal bluetooth receiver/transmitter.

I've also tried to use the bluetooth explorer to debug the bluetooth device, this has gotten me this error:

"updateChainPower error: -3903

2020-04-10 13:11:13 +0000 Apple80211Get(APPLE80211_IOC_BTCOEX_MODE) returned error -3903"

Got mine back in 3 days at a official repair point, should never take 4 weeks!

Trust me, just got mine back from the repair point and the replaced the whole board just like others explained here. The internal BT just doesn't work and they have to replace the whole board, just do it under warranty and your all good to go after a few days/weeks.

Make sure to never plugin a BT dongle again :)

Both wifi and bluetooth failed on me. As with others, I am using dongles. I asked Apple for repair but they insisted I ship it in rather than do it at the store.

I am teacher, currently trying to carry-on distance learning. Being without my mac for a week or more is impossible. I had hoped they would swap out the Macs, I even offered to pay something for it, but no dice.

All my experience with Macs (I have owned one since 1984) has always been good until this time. I had this Mac for barely 3 months. I really feel like this company has lost its soul.

Like I mentioned before @jdharris56 i`m a windows guy and i bought the mac for my surface book and this was for sure the last mac I own.

Here, in germany, the said on chat twice that I cant send it it in and I should bring to a store nearby me...then they look up and found out that the next store is roughly 110 kilometer (about 160 US miles ) from my home PLUS due to corona virus I cant drive there because of the quarantine.

So what is the solution ? Sit there and wait til I can drive there 2 times to bring and pick it up? Who pays me for this? Never experienced such a bad service...

Best thing is - what happens when it is repaired? I always have to be scared that I forget to pull my BT receiver from my dock ..otherwise this thing blows up again? Pretty cool solution as far as you ask me. I really would like to go to the store and when I pick it up i will again attach my BT dongle there and let it blow up again...really. Here in germany if the same error occurs 3 times in a row and It cant get fixed you have to get your money back...thats what the law here says.

Maybe the best solution because not attaching a dongle anymore is really crap - because I know it will happen again.

I have exactly the same problem.

WTF apple... Tried everything, restarting PRAM, SMC, boot into diagnostics mode. Nothing. BT is completely dead, can't find any device.

BT Explorer shows no Host Controler.

US has similar 'Lemon' laws.

Issues related to power (mis)management and thermal overload, bad chip packaging have dogged Apple for a long time.

You’d think the people at the repair depots would be noticing the frequency of problems.

There is a Repair Frequency Index by year/Mac model/manufacturing location/serial number/replaced part serial number and type. 😉 Repeat Repair Index tracks the number of times a given serial number comes back for warranty repairs.

There is a very unhappy bunch of engineers and managers somewhere on this planet. And this is not the first time!

I'm afraid they don't give a fuck. My 3500€ laptop is at repair since March the 1st. Yesterday I got Apple Europe (Ireland) customer services on the phone, they don't offer anything but "wait" (meanwhile new machines are on stock).

This story is likely to end in a trial, and even worse, an unhappy user.

The 2011 AMD GPU problems are well documented. The nVidia GPU (GT series) issues are also similar. It is very hard on the end-users. There is no easy solution for a new model, and the current supply chain issues do not help either.

I just got the same issue, I am using razor x chroma as for thunderbolt, I have tried all and plus even wasting time with apple care, format the computer, installed bootcamp too for windows 10. Over there the same ble is not working either after the issue. This sucks big time. Now they want to fix the computer, but it seems more likely another bad step from apple engineering. For me when doing the check up (D) it telling me all is good but obviously it is not working.

what did you do at the end?

I got also the 2011 MBP, I was like over there as it lasted me around 9 years then I got this one and again.

I hope they find a solution but I really doubt that, money has been spent already they don’t care anymore.

i was screaming out loud but your system is quite more expensive than mine and it is out for warranty 2-3 months. This is amazing. I hope your system get fix soon. Thanks to your post I will wait for it to get it fix.

After 2010, I only bought refurbished Macs. The only exception has been a 2018 Mini. My experience has been to wait for at least a year after a new model is released, before I consider a purchase. The 15-in line-up is a much more stable lineup.
