Documentation (for GATTPeripheral)

Would it be possible to provide some documentation or examples of using GATTPeripheral to accomplish something like this?

Also any help would be appreciated, as my peripheral with service and characteristics isn't working for some reason even though nothing that can throw is throwing and it should be discoverable..

(I'm not an expert, but have a good understanding of bluetooth/GATT. I have setup a custom python GATT server that does similar things to the bluez example in the above link. I also have written the Central that talks to it in Swift on iOS - however porting the python code to pure swift so far is proving to be more difficult than anticipated.. )

Kind regards,

Can't figure out how to dynamically set read value on a characteristic based on central UUID

I'm trying to implement a peripheral on a Pi that looks at the central's UUID on a willRead and figures out the reply based on some business logic. The problem is that because peripheral.write is async, there doesn't appear to be a way to dynamically change the value on a willRead in time for the response to go out.

Is there a recommended pattern to follow for this:

private func willRead(_ request: GATTReadRequest<Central>) -> ATTError? {
        logger.info("Recevied read")
        guard let peripheral else {
            return nil
        }
       /// SET THE VALUE OF THE CHARACTERISTIC
}

Implementing a cross platform GATT Peripheral

Using PureSwift GATT I wish to implement a GATT Peripheral that will be deployed on Darwin (MacOS, iOS, Mac Catalyst) and Linux platforms. How can a peripheral such as a Heart rate Monitor be implemented without custom coding for each platform?
Perhaps I am missing a trick?

Implement CoreBluetooth state restoration

CoreBluetooth state restoration needs to be properly implemented, and be an optional feature. Since CoreBluetooth uses Objective-C runtime introspection to check if the CBCentralManagerDelegate instance implements the state restoration delegate methods, it makes optionally enabling this feature a bit more difficult.

Unable to subscribe to notifications for characteristics from different services on Darwin platforms

Issue

Subscribing to notifications for characteristics from different services is not working as expected on Darwin platforms (iOS and macOS).

Expected Behavior

I'd expect for the notification handler to be triggered for all of the characteristics I subscribe to, even if those characteristics are from different services.

Observed Behavior

Only the last characteristics I subscribe to from a single service have the notification handlers called.

Possible Cause

I've done some initial investigation and the cause of this limitation may live in the Cache of DarwinCentral.swift:

GATT/Sources/DarwinGATT/DarwinCentral.swift

Lines 781 to 823 in 5752c67

struct Cache {
fileprivate init() { }
var services = Services()
struct Services {
fileprivate(set) var values: [UInt: CBService] = [:]
}
mutating func update(_ newValues: [CBService]) {
newValues.enumerated().forEach {
let identifier = UInt($0.offset)
services.values[identifier] = $0.element
}
}
var characteristics = Characteristics()
struct Characteristics {
fileprivate(set) var values: [UInt: (attribute: CBCharacteristic, notification: ((Data) -> ())?)] = [:]
}
mutating func insert(_ newValues: [CBCharacteristic],
for service: CBService) {
// remove old characteristics for service
while let key = characteristics.values
.first(where: { $0.value.attribute.service === service })?.key {
characteristics.values[key] = nil
}
// insert new characteristics
newValues.enumerated().forEach {
let identifier = UInt($0.offset)
characteristics.values[identifier] = (attribute: $0.element, notification: nil)
}
}
}
}

The Cache stores Services and Characteristics as siblings. The Characteristics are stored by the index / order that they were discovered in.

This means that if you discover characteristics from Service A. Then discover characteristics from Service B. The characteristics from Service B overwrite the characteristics from Service A.

Additional Information

Depending on how the caller discovers / subscribes to notifications, this may result in an Invalid characteristic assertion failure when attempting to call the notification handlers:

GATT/Sources/DarwinGATT/DarwinCentral.swift

Lines 595 to 598 in 5752c67

guard let cache = self.internalState.cache[Peripheral(corePeripheral)],
let characteristicCache = cache.characteristics.values.first(where: { $0.value.attribute === coreCharacteristic })?.value
else { assertionFailure("Invalid characteristic \(coreCharacteristic.uuid)"); return }

[Linux] Command Disallowed

With this test program:

import GATT
import Bluetooth
import BluetoothLinux

typealias LinuxCentral = GATTCentral<BluetoothLinux.HostController, BluetoothLinux.L2CAPSocket>
guard let hostController = await HostController.default else { fatalError("No Bluetooth hardware available") }
let central = LinuxCentral(hostController: hostController, socket: BluetoothLinux.L2CAPSocket.self)

// start scanning
let stream = try await central.scan(filterDuplicates: true)
for try await scanData in stream {
    print(scanData)
    stream.stop()
}

I'm getting Swift/ErrorType.swift:200: Fatal error: Error raised at top level: Command Disallowed (even with sudo).

I'm on an Ubuntu 20.04.2 LTS derivate. Any idea what could be wrong?

GATT peripheral does not advertise services

Services added to a GATTPeripheral are discoverable once a remote central has connected, their UUIDs are, however, now included in the LE advertising payload. This causes nodes acting as a GATTPeripheral to go undiscovered if the central scans for specific service UUIDs.

Implementing glucose services, need help

I want to implement BLE stuff regarding blood sugar measurement and found this project.
Is there any chance to get general starter information regarding how to implement a simple read workflow of an characteristic: connect device, peripheral service discover, manage notify values, read and write characteristic data?

I took already a look at https://github.com/MillerTechnologyPeru/SmartLock, but honestly, it's not very helpful to get started.

Any help appreciated!

Beacon and Service Advertisement

Decrease CPU usage when scanning

Use a different strategy that doesn't involve sleep() while scanning to improve energy efficiency and decrease unnecessary CPU usage. DispatchSemaphore might be a good solution.
