Sample Client

import asyncio
from vnsconnect import VNSconnect


async def client():
    vns = VNSconnect("")

    config = vns.create_sysconfig(
        imu_odr=10, mag_odr=10, to_ble_imu=True, to_ble_log=True, to_ble_mag=True, to_ble_quat=True)

    await vns.connect_to_tracker()

    address = vns.get_address()
    print(f"{address}")

    await vns.write_config("sys", config)
    await vns.read_config("sys")
    await vns.start_notification()      # No timeout

    try:
        while True:
            await asyncio.sleep(1)
    except KeyboardInterrupt:
        pass

    await vns.stop_notification()

    await vns.disconnect()


if __name__ == "__main__":
    print("Starting VNSconnect client... press CTRL+C to terminate")
    asyncio.run(client())
