Hello, I'm trying to find the distance of ibeacon with raspberry pi and when I run the python code I get the following error;

File "indoor.py", line 29
if 0<= calculate_accuracy(txpower, rssi)calculate_accuracy< 2:
^
SyntaxError: invalid syntax

You have extra calculate_accuracy on that line

I've solved this problem, but now I'm suffering from a bluepy installation.

Error:
pi@raspberrypi:~ $ sudo pip install bluepy

are you running behind proxy?
If you google the error you will see it could be number of reasons

I guess that's why I'm using the dorm Internet. I think there's restriction.

@buran I have now installed the internet from my phone. Now I have this problem.

Traceback (most recent call last):
File "indoor.py", line 1, in <module>
import blescan
ImportError: No module named blescan

where your code comes from? what is bluescan? i.e. if you create the code you should now what package module it is. is it installed? is it the one part of bluepy?
Obviously it's this one https://github.com/magitnus/bluescan/blo...blescan.py
and it is based on https://github.com/adamf/BLE/blob/master/ble-scanner.py

@buran I apologize, but I can't find the ibeacon this time.
so I could not access the files that solved the problem.
pi@raspberrypi:~/Desktop/bluetooth_indoor_localization $ python indoor.py
ble thread started
error accessing bluetooth device...

I just can't find the device right now.

I really cannot help more

okay but why ?

sorry, i didn't realise it's your code that print that error accessing bluetooth device... and I didn't have any idea why you cannot access the device.
remove the try/except block.
by using blank except you shadow any exception message that will tell what's wrong
you should always use specific error that you can catch

EDIT: I see - scan(sock) should be scan_sock(sock)
