Hello
everyone, I am a new bee to raspberry pi. I am working on a project with arduino + HC-05 and raspberry pi 3
I have wrote a code to arduino to send temperature data to pi over bluetooth, and python code to receive the data. The python code throws error could not import bluetooth. Please can someone help me to rectify this...

Hope fully this is the last post and solution 
after following the steps in the link I posted above I did the following
sudo python3.4 -m pip install pybluez
this succesfully allowed me to import the bluetooth package in python 3.4, for python3.5 try:
sudo python3.5 -m pip install pybluez
don't forget to do it as root (with sudo). If this fails to work I can only assume that pybluez hasn't been ported over to python3.5 and you are out of luck
Hello World !
I wonder if this project is always in progress... But if it is, I have some informations for you, maybe.
In fact, Python 3.5 or above no longer accept pybluez module directly.
By now, Python3 calls BlueTooth as Socket with "Command Type", "Socket Type" and "Protocol Type" parameters, so in your case, this is a typical script :
# --------------------------------
#!/usr/bin/env python3 # Only if OS is not Microsoft 
Windows
import socket # Socket module is used for network and bluetooth in Python3.5 and above
MACAdrBluetoothModule = 'XX:XX:XX:XX:XX:XX' # MAC Adress of the Bluetooth sender, not the RaspBerry Pi
BluetoothChannel = 1 # Indicate the appropriate transmission channel (generally 1 for a serial bluetooth module as HC-05)
SizeOfDataInBytes = 2 # Indicate the appropriate number of bytes you want to receive
# Function created for data read
def lecture_serie(MACAdrBluetoothModule, BluetoothChannel, SizeOfDataInBytes):
Connection = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_STREAM, socket.BTPROTO_RFCOMM)
try:
Connection.connect((MACAdrBluetoothModule, BluetoothChannel))
ReceivedData = Connection.recv(SizeOfDataInBytes)
ReceivedData = str(ReceivedData.decode('utf-8')) # To translate data to a correct string UTF-8 data
except IOError:
ReceivedData = "ERR"
return ReceivedData
Connection.close()
# --------------------------------
So, every times you want to read the bluetooth serial data, you just use this function and it returns the received data by the RaspBerry Pi.
For example :
print(lecture_serie(01:23:45:67:89:AB, 1, 1024))
It will return 1024 bytes from the serial Bluetooth module where its MAC adress is 01:23:45:67:89:AB and its channel is 1.
So, good luck for your project,
Bye ! Best regards.
