This is an unofficial Sphero library for BLE toys.
The Sphero protocol is reverse-engineered using the official Sphero Edu application for Android and this library.

This code is tested only on Sphero Bolt. Probably it will work on the other BLE toys too.

For using this library need bluepy and libgtk2.0-dev.

# apt-get install libgtk2.0-dev
# pip install bluepy

# To use gatt BT stack, install it manually
# pip install gatt

# To use bled112 dongle, pygatt for BGAPI is supported
# To use pygatt BT stack, install it manually
# pip install pygatt

To install pysphero use pip:

# pip install pysphero

from time import sleep

from pysphero.utils import toy_scanner


def main():
    with toy_scanner() as sphero:
        sphero.power.wake()
        sleep(2)
        sphero.power.enter_soft_sleep()


if __name__ == '__main__':
    main()

While using gatt, if you are facing connection issues

# Connection failed: Device does not exist, check adapter name and MAC address.

You must check if your BLE device is known on your system list (thanks to bluez-tools).

# bt-device -l

If not, used bluetoothctl to do so.

sudo bluetoothctl
Agent registered
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# scan on
[CHG] Controller AB:CD:EF:12:34:56 Discovering: yes
[NEW] Device 12:34:56:78:90:AB (your Sphero toy)
[bluetooth]# exit

BLE device list must have been populated

Packet contains sourceID and targetID. Their meaning is unknown.
