Bluetooth OBEX Profile Support Documentation?
I'm connecting to an iPhone 12 via Bluetooth for access to PBAP, HFP, and MAP for sending, receiving, and listening to messages/calls. Note that this is not via any kind of custom hardware but rather through a PC. When I try to run basic commands like GetMessagesListing, it always comes back empty. I can hook some events, so I at least get something, but nothing compared to other platforms. That said, is there any documentation that describes what is supported for each Bluetooth profile? I've searched through the documentation for Core Bluetooth but wasn't able to find answers to that specific question. From what I can gather, this is something that Apple doesn't seem to support as opposed to me doing it wrong. Any help is appreciated, -Dew

Recent Bluetooth Flakiness on MacOS Monterey 12.1
I have MacOS Monterey 12.1 on an iMac (Retina 5K, 27-inch, Late 2015). After a recent Monterey update, the Bluetooth began to drop and eventually reconnect the Trackpad 2. Even after purchasing a new replacement Trackpad 2 from Apple, the issue persists. The issue can occur frequently or with an hour or two of intermittent stability. When the connection drops, it usually (but not always) reconnects in some random number of seconds or minutes. Several steps have been taken that DO NOT resolve the issue: Delete /Library/Preferences/com.apple.Bluetooth.plist Delete ~/Library/Preferences/ByHost/com.appl.Bluetooth... Shutdown bluetooth and reboot Reset NVRAM/PRAM Reset SMC I have been unable to locate any logs on my MAC that provide more detail on bluetooth connections/issues. Questions Is there a fix for this recently-introduced issues OR is there an option to rollback the latest updates? Are there logs that can clarify the underlying issue(s) OR is this an oversight in the design?

iBeacons broadcasting on background for long time
Hi, We have an app that broadcast UUIDs as beacons to the Suntech vehicle tracker device in the foreground and background. This app broadcast UUIDs to vehicle tracker devices when the app is in range of the device, and when the application is away from the device then it will send alerts to users. But this is working properly when the app is in the foreground. And when the user puts the application in the background then broadcasting stops and UUIDs format is also changed. So can you guide us, on how we can broadcast in the background for a long time and when the app is killed?

Background ble
I want to send encrypted data from ble (as central) to another device (as peripheral). Now when app is open everything is all good, but what to do if app is in background? Do I have to buy smaller version of advertising id from BLE SIG? OR Is there any way I can send data in background? Or Is there any unique characteristics or services other than BLE ADDRESS that iPhone always advertises when iOS Bluetooth is turned on, so that I can check on that condition and allow entry to user (as application is for smart door lock.)

Can Customize Bluetooth HID usage page/usage be accessed by application on macOS?
We developed a bluetooth keyboard with classical bluetooth, and used usage page 0x01 and usage 0x03 for OTA firmware update, and I wrote an appliction on Windows 10 and everything works as expect. I am trying to wrote same application on macOS Big Sur 11.6.1 with XCode 13.2.1, but I found that DeviceMatchingCallback was triggered only once with usage page 0x01 and usage 0x06, which is keyboard usage page/usage pairs, any other usage page/usage pairs such as 0x01/0x03, 0x0C/0x01 didn't trigger DeviceMatchingCallback. So my question is: can customize usage page/usage of bluetooth hid be accessed by application?

CoreBluetooth stopped working in my app
Hello, I am the developer of an app that is published on the App Store. This app connects to Bluetooth devices to read their battery levels. However, it seems that CoreBluetooth, which is used to discover and connect to devices, has completely stopped working on macOS Monterey. The delegate methods are no longer triggered. When I start my app I see the following messages in the output area: [CoreBluetooth] No name or address The Console app shows a lot of this messages: error 14:56:23.730415+0200 bluetoothd Server.Core sdp attributes is empty I don't know if this is related in any case. Are there any new entitlements or something like that? I did not change any single line and on Big Sur, everything works fine. A customer of mine, which also uses the beta version, already contacted me, so this seems to be a general issue - at least with my app? The app also works fine on Big Sur for the customer.

Bluetooth Headphones Crackling and Popping
My Bluetooth headphones are cracking and popping. This topic is on a lot of forums but I haven't found any fixes. Some of them are quite old. There is a really long run on this forum in fact years however there's not a fix for me. I did have success with reset the Bluetooth module this morning and it cleared up the distracting noises. I/m back on my computer this ever working in Logic Pro X and it's back. ANY HELP would be greatly appreciated. Thank You in advance. I have a late 2105 iMac Big Sur 11.4 Graphics: ADM Radeon R9 M390 2 GB 32 GB RAM

How to capture Bluetooth notifications on Mac and iOS?
I want to capture Bluetooth "Classic" device notifications on both Mac and iOS platforms primarily when: Bluetooth is turned on/off When a device gets connected/disconnected to Bluetooth On Mac: I used the IOBluetooth framework in Mac for this by registering for two notifications: registerForConnectNotifications registerForDisconnectNotifications However, the issue with this is that notifications get triggered even when a connect request happens with the device. (For ex: I pressed connect for connecting with headphones and a notification is received even though it failed to connect to the device for whatever reason). I need the notification to be received only when the device is successfully connected with the system. On iOS: I am not sure which framework to go with - whether CoreBluetooth or External Accessory. I did read that CoreBluetooth supports classic devices but not every device. I would appreciate any insight or help on this topic.

Discover and connect to BT speaker via API
Hi all, is there anything available in the iOS SDKs to allow me to find and connect to a bluetooth speaker? At the moment I have to direct users to iOS settings and do it from there, but I would like to have an in-app experience for this. Thanks!

Random Spaces Inserted into Barcode Scan
Multiple barcode scanners will work properly when hard-plugged into Windows device but will insert random spaces into Notes when bluetooth-connected to iPad mini 4 (running 15.1), even if the settings are for a mac OS device. Thoughts?

Connect to Rasberry Pi
I can see my pi listed in iOS settings, and I can connect to it that way. I'm also trying to connect using CoreBluetooth but the pi never appears as a Peripheral I can connect to. Should I be taking another approach? Would it appear as an ExternalAccessory instead? I have a Python server on the device that I'd like to connect to. Thanks!
