bleak/examples/service_explorer.py program errors

[Bipman1]

Hi

I am trying to run the Service_explorer example program on a PC to get the services of a BLE device. I get the following error

TypeError: 'str' object is not callable

There is a device called Gloving as I can connect to it using a Ble scanner on my phone and the PC. Any idea what it might be? I'm just trying to find out the services given by the BLE device as for some reason the Service UUIDs are different to the ones I programmed.

Can you please give the exact steps to reproduce the problem?

Hi I run the program from the Windows CMD line with 'python --name Gloving' and that is when I get the error message, so nothing unusual. Are there any other logs I can look at?

Thanks, I'll check it out.

Hi Checked it out and the error output is attached. Not sure but it looks like I'm getting there but also not sure if the errors are normal or not. Also, how do you reconnect when the BLE goes to sleep? SPG

GitHub discards email attachments. You have to use the web interface to attach files.

Ah, here you go.

The device is disconnecting right away. You would need to log Bluetooth packets to see what triggers the disconnection.

[Bipman1]

Ok, thanks.
