I am running the latest Raspbian Stretch on a Pi 3b+ with Swift 4.1.1 installed from https://packagecloud.io/swift-arm/test?page=1

I upgraded Package.swift to Swift 4, rearranged the directory structure to match, fixed few random incompatibilities (e.g. flatMap -> compactMap, etc) and encountered:

swift: /home/linaro/RaspberryPi/buildSwiftOnARM/swift/lib/Serialization/Serialization.cpp:617: TypeID swift::serialization::Serializer::addTypeRef(swift::Type): Assertion `!ty->hasError() && "Serializing error type"' failed.
[snip stack dump]
1.	While serializing type 'τ_0_1'

<unknown>:0: error: merge-module command failed due to signal 6 (use -v to see invocation)
error: terminated(1): /usr/bin/swift-build-tool -f /home/XXXX/Bluetooth/.build/debug.yaml test -v output:

This seems to be the same compiler bug as: https://bugs.swift.org/browse/SR-6754

By playing around I think I have tracked it down to the compiler getting confused on the default static var in BluetoothHostControllerInterface, though its not clear why it would.

When I remove that variable and its definition in the protocol extension, compilation proceeds normally.

Has anyone else gotten Bluetooth compiling under swift 4.1?

Add TestL2CAPSocket for unit testing GATT Client and Server.

Implement all HCI comment sent for LE operations.

Add RSSI.dBm

https://support.dialog-semiconductor.com/convert-rssi-dbm

Decrease the framework binary size by removing non-essential Bluetooth types for iOS, tvOS and watchOS. HCI Commands and Events, non-supported GAP Data types by CoreBluetooth and ATT PDUs cannot be used from iOS.

Implement GATT Descriptor procedures (Discovery, Read, Write).

Implement HCI Informational Parameters Commands to read controller values such as device address.

Depends on #6. Create dummy TestHostController for unit testing HCI commands and GATT operations.

Allow compiling for Swift 4.2 in Xcode 10

Depends on #7. Add protocol extensions that serve as convenience functions to easily configure the Accept Connection Timeout parameter on the Bluetooth controller.

Update the BluetoothUUID defined UUID list (in DefinedUUID.swift) from bluetooth.com.

UUIDs are used in Bluetooth® protocols and applications. The SIG provides UUIDs for all the types, services and profiles it defines. The UUID program will run until the available block of 512 UUIDs is fully allocated. A fee of $2,500 per UUID will be charged for each.

Implement the standard GATT Characteristics in GATTCharacteristic.swift by implementing the GATTProfileCharacteristic protocol.

Implement ATTHandleValueNotification for GATT Server and Client.

Depends on #33.

Write Connection Accept Timeout Command in
BLUETOOTH SPECIFICATION Version 5.0 | Vol 2, Part page 925

GATTServer should not be sending GATT notifications to the connected client that wrote the value.

• If the Peripheral wrote a new value, all connected clients should be notified.
• If a Central wrote a value, all connected centrals, except the one that wrote the value, should be notified.

The project currently has GATTCharacteristic.swift and ATTProtocolDataUnit.swift which contain over 20 types and over 2k LOC, as well as the HCI commands. We need to separate the project into one file per type (with nested types as exception). This source layout will prevent merge conflicts and make the project scalable for rapid development with a larger team, but at the cost of git history. There is also the worry of a limit of number for files, and longer compile times with Xcode and Swift Package Manager, but this approach is cleaner and scalable.

This should not affect the API, but we might need to rename some of the HCI commands since the Swift compiler has issues compiling nested types in extensions across different files based on the order of input files. This bug is not present when Whole Module Optimization is enabled.

Integrate SwiftLint into the Xcode project.

The parameter packetpayload: LowEnergyPacketPayload is not being using.

Create an Adapter protocol to represent Bluetooth adapters in a abstract type, and create a dummy TestAdapter in the unit tests to test HCI commands.

Improve performance of library when used across modules as a shared library (e.g. .so, .dylib, .framework).

Building the package on Xcode 12.5 I am getting such an error on line
public static let allCases: Set<MajorServiceClass> = [
in
ClassOfDevice.swift.

Implement the GAP / EIR / BLE Advertisement Data Types.

Implement HCI Inquiry procedure. Depends on #100.

• Create AppleBeacon struct with parameters. See PureSwift/GATT - Beacon.swift.
• Use GAP data types (depends on #44)
• Check if controller supports LE features (Read Local Features HCI Command).
• Read LE Advertising Power (depends on #3).

Separate the code into separate libraries and remove the platform conditional compilation introduced in #108 for modular and smaller binaries.

The unit tests for failing with Swift 5 and Xcode 10.2.

Add Class of Device struct according Bluetooth Documentation

Implement BLE mesh protocol.

Implement the new CaseIterable protocol introduced in Swift 4.2

This will allow enum cases that currently rely on BitMaskOption.all to have the compiler synthesize the value (and prevent missing cases in the set).

Integrate xcov and generate code coverage to be published with GitHub Pages.

Hello,
I'm desperately trying to revive this project that is based on your libraries stack.
This project is quite old and I've make forks of your libraries and this library to update it and make it compile on Ubuntu.
Unfortunately after I've fixed some issues, mainly due to misalignment between swift version and libraries version, I've found myself stuck with those kind of errors during the linking phase.
Project itself seems to build fine, but as soon as I try to test it swift test it shows me that error.

It seems that is looking for some mangled methods and properties that should be present in BluetoothGATT that are referenced from the project but it can't find them.
I've tried different solutions for instance use GATT module definitions (but it seems to be just a proxy if it can import BluetoothGATT).
I really do no not understand what I'm missing, tried to reach the original creator of the library but he/she is not responding.
Could you point me to the right direction?
Best,
Andrea

Add ATT PDU mock data and unit tests.

Implement HCI_Write_Local_Name and HCI_Read_Local_Name.

See BLUETOOTH SPECIFICATION Version 5.0 | Vol 2, Part E page 923

Integrate Jazzy to generate documentation.

Android always provides 128 bit UUID.

Add human readable names for HCI commands.

Optimize parsing of Data for HCI commands, events, and ATT protocol data units. Migrate from parsing only Data to parsing from Data.Subslice or a similar type. This is to avoid unnecessary instantiating Data buffers when decoding bytes.

Implement a function for data types like ATTProtocolDataUnit that will encode data while reusing and growing a buffer, instead of copying into a buffer.

Well, the time has finally come. This project currently supports Swift 3.0.2 - 4.2. While that is impressive, since Swift 4.1.2 is available for Linux ARM, there is no reason to continue supporting Swift 3 anymore.

Implement HCI Link Control commands and related events.

Modify HostControllerInterface.pollEvents() and its implementation in BluetoothLinux to allow for different types of events.

Update the list of registered CompanyIdentifier from bluetooth.com.

Company identifiers are unique numbers assigned by the Bluetooth SIG to member companies requesting one. ​​​​

The LE Scanning is currently only taking into account LE Advertising Data, not the LE Scan Response data.

See how Android currently handles scanning and advertisements.

Implement the standard GATT Descriptors found in GATTDescriptor.swift by implementing the GATTDescriptor protocol.

The defined Bluetooth Units should be specified in a list and automatically generate the extensions and unit tests. The member names should be manually defined and not sanitized from the documentation.

Implement GATT Indication / Confirmation procedure.

This is not severe but the outputs of below warning always pollutes the console:

Add validation os(Android) on POSIXError.swift.

#if os(Linux) || os(Android)

Implement the standard GATT Profiles.
Depends on #58.

Generic Attributes (GATT) services are collections of characteristics and relationships to other services that encapsulate the behavior of part of a device.

A GATT profile describes a use case, roles, and general behaviors based on the GATT functionality, enabling extensive innovation while maintaining full interoperability with other Bluetooth® devices.
