The root directory contains the core objects and type aliases for typical use of the SDK.

📁 Combine — Primary Combine operators used to control MetaWear devices
📁 Cpp Bridging — Swift wrappers around sensors/modules (e.g., gyroscope), commands (e.g., activate iBeacon), and anything else from the C/C++ library
📁 Helpers — Extensions and utilities

📂 MetaWearSync — iCloud synchronization of device identities

📂 MetaWearFirmware — Updates device firmware from MetaWear servers

📂 MetaWearCpp — Underlying C/C++ submodule

Hi,

I think the documentation may be wrong or the immediate flag is not working as documented. Currently, if I run this code:

        sub = metawear
            .publishWhenConnected()
            .first()
            .createTimedEvent(period: 2000, repetitions: 2, immediateFire: false, recordedEvent: {
                let command: MWCommand = .led(.blue, .blink(repetitions: 3))
                command.command(board: metawear.board)
            })
            .handleEvents(receiveOutput: { timer in
                mbl_mw_timer_start(timer)
            })
            .sink(
                receiveCompletion: { completion in
                    print("COMPLETED: \(completion)")
                },
                receiveValue: { value in
                    print("VALUE: ", value)
                }
            )

It runs as expected and the LED fires after 2 seconds. Yet, according to the docs, the immediateFire flag should negate the need to call mbl_mw_timer_start, however, if I run this:

        sub = metawear
            .publishWhenConnected()
            .first()
            .createTimedEvent(period: 2000, repetitions: 2, immediateFire: true, recordedEvent: {
                let command: MWCommand = .led(.blue, .blink(repetitions: 3))
                command.command(board: metawear.board)
            })
            .sink(
                receiveCompletion: { completion in
                    print("COMPLETED: \(completion)")
                },
                receiveValue: { value in
                    print("VALUE: ", value)
                }
            )

Nothing happens and the timer does not seem to run the specified LED command.

Additionally, it would be nice if createTimedEvent worked similarly to recordEvents where command closure has the board as an argument.
