I am making the python script for the read/write connect/disconnect. So it would be a great if you can share your script

My setup is ubuntu 64 bit with python 2.7.

Thnaks,

Hi everyone,

I finally managed to make everything work fine with python (bluepy).

Unfortunately, the only cmd line working is the scan "sudo hcitool lescan" to get MAC_ADRESS

I am still unable to connect using "gatttool -I -b MAC_ADRESS" or "sudo hcitool leccMAC_ADRESS". @Bjørn Kvaale, I red you links, I managed to scan properly using this link but It doesn't change anything about connecting.

Lucky for me, I only needed to connect, activate notifications, and use incoming events using Bluepy (python library), and this worked.

To install bluepy library, I used theses setps

I could share my python code if needed.

Thanks for your help, and have a good day !

Sincerely

Have you googled your error yet? I found these three links that could be helpful: link 1, link 2, link 3

By editing the /etc/group file you could give your user permission to access bluetooth peripheral. But if sudo did not solve the problem this won't either.

Thanks for your comment. I didn't mention it, but yes I ran hcitool using sudo. What do you mean by adding user on bluetooth, netdev and plugdev groups ?

Thanks !

Looks like user permission. Have you tried running hcitool with sudo? Adding your user on bluetooth, netdev and plugdev groups should allow your user to access bluetooth connection.
