getting error on Bluetooth LE Console steps

[hirenthumar]

Hi Support Team,

Have a nice day.

Board: NRF5340DK

Python version: 3

nRF Connect SDK version 2.6.99

We are selecting the NRF5340DK for development purposes and are developing a peripheral testing command on the Zephyr shell. Currently, we can test through the UART Zephyr shell.

We want to perform the same tests through BLE. I found an NRF note about the Bluetooth LE Console here.

As per the provided link, we are trying to compile the code from the repository, but we are encountering errors with Python 3. Could you provide the steps to compile this code in the latest Python environment?

Thank you.

It would be helpful to know which Linux distribution you try to use in what version, and what error messages you got.

1.

Linux version:

Distributor ID: Ubuntu
Description: Ubuntu 22.04.4 LTS
Release: 22.04
2 . Resolved Error when we executed with $ python3 BluetoothConsole.py and now we are getting BLE console

  $ python3 BluetoothConsole.py
  Traceback (most recent call last):
  File "/home/soho/.local/share/Trash/files/ble_console/BluetoothConsole.py", line 19, in <module>
  from BlueZ_communication import BluetoothConnection
  File "/home/soho/.local/share/Trash/files/ble_console/BlueZ_communication.py", line 184 
  print e.args
  ^^^^^^^^^^^^
  SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?
 

  $ python3 BluetoothConsole.py
  Traceback (most recent call last):
  File "/home/soho/.local/share/Trash/files/ble_console/BluetoothConsole.py", line 19, in <module>
  from BlueZ_communication import BluetoothConnection 
  File "/home/soho/.local/share/Trash/files/ble_console/BlueZ_communication.py", line 50
  bashCommand = 'bluetoothd -v'
  TabError: inconsistent use of tabs and spaces in indentation

But when we executed the below steps, the BLE device did not show our BT_NUT_shell hostname. before executing it is seen

nano /etc/systemd/system/bluetooth.service

ExecStart=/usr/lib/bluetooth/bluetoothd -E

sudo service bluetooth restart

Script is br0ken since at least NCS v2.2.0 - and nobody noticed that yet. I don't have older versions on my disk here to check.

Hi,

The Bluetooth LE Console is outdated and requiers python 2. It should be python 3 compatible if you fix the print staement in BlueZ_communication.py line 176, though (add parenthesises as print is a function call in python 3). There may be other issues with recent distroes also, though.

May I ask for wha tyou intend to use it? Perhaps there are other alternative approaches that would be better?
