BLE example
Here is an example of driver to send messages using BLE
Setup on robot (or other BLE advertiser)
Copy following files to robot
- aioble/*
- RobotBleServer.py
- mainRobotTestBLE.py (to rename as main.py)
You can use script toRobot.sh for that, for example when run from a Windows git bash, if robot is connected on drive D:, you can run
./toRobot.sh /d
Setup on USB dongle
Copy following files to robot
- aioble/*
- mainDongle.py (to rename as main.py)
You can use script toDongle.sh for that, for example when run from a Windows git bash, if dongle is connected on drive E:, you can run
./toDongle.sh /e
Setup on computer
You need pyserial module for python. You can install it using command
python -m pip install pyserial
or if a proxy is required
python -m pip install --proxy <http proxy parameter> pyserial
Then run following command
python mainPcTestBLE.py --portcom <com port used by dongle>
To know COM port to use as argument, run following command before and after dongle connection:
python -m serial.tools.list_ports
Port in second result but not in first result is port used by dongle.
Connect on the good robot
When several robots are started at same time, they shall have a unique identifier so you can connect over BLE on the good robot. For that, you shall replace "myTeamName" by a unique identifer (for example the name of your team) in following files:
- mainRobotTestBLE.py
- mainPcTestBLE.py
Note relative to BLE
The Bluetooth is a connection with a limited transfer rate. If you try to send a lot of messages in a short period of time, or transfer long messages, the BLE driver will do it's best to transfer all data but expect delay to receive messages on the other side.
