Library for using the bleuio dongle.
Project description
##Python library v1.1.2 for BleuIO
Supports BleuIO v.2.0.4
Instructions
- Install the library by running:
pip install bleuio
- In the python file import:
from bleuio_lib.bleuio_funcs import BleuIo
- Initialise an object with BleuIo. You can leave the parameters empty for auto detection.
# Auto-Detect dongle
my_dongle = BleuIo()
# Specific COM port (Win) 'COMX'
my_dongle = BleuIo(port='COM7')
# Specific COM port (Linux) 'dev/tty.xxxxx...'
my_dongle = BleuIo(port='/dev/tty.123546877')
# Specific COM port (Mac) 'dev/cu.xxxx...'
my_dongle = BleuIo(port='/dev/cu.123546877')
- Start the deamon (background process handler) for rt and tx data.
my_dongle.start_daemon()
- Access all BleuIo AT-commands from my_dongle object.
- The functions return a string list.
- Don't forget that you can stop started scans with:
my_dongle.stop_scan()
and SPS streams with:
my_dongle.stop_sps()
Just remember that scans and streams will run indefinitely if not otherwise specified. They will not return data until stopped using .stop_scan() or stop_sps(). Once stopped you can collect the data from my_dongle.rx_scanning_results or my_dongle.rx_sps_results. You can get a live feed by listening to .rx_buffer().
Some examples can be found in bleuio_tests\test_bleuio_funcs.py
NOTE: The streaming functions of the at_spssend() is unstable. We are working on fixing it. The at_spssend() command with parameters works fine and we suggest you use that instead untill a bugfix is released.
