|
|
//| =========================================================

//|
|
|
//| Implement a BLE broadcaster which sends data in advertising packets and does not connect.
|
|
//| Used for beacons and other one-way data transmission.
|
|
//|
|
|
//| Usage::
|
|
//|
|
|
//| import bleio
|
|
//| import time
|
|
//|
|
|
//| # Broadcast once a second.
|
|
//| broadcaster = bleio.Broadcaster(interval=1)
|
|
//| data = 0
|
|
//| # Broadcast a byte of data that's incremented once a minute
|
|
//| while True:
|
|
//| # data is an entire advertising data packet, starting with flags.
|
|
//| broadcaster.start_advertising(data)
|
|
//| time.sleep(60)
|
|
//| data += 1
|
|
//|
|
|
//| .. class:: Broadcaster(interval=1)
|
|
//|
|
|
//| Create a new Broadcaster object.
|
|

//| :param float interval: how often to broadcast
