Bluetooth starter code error

[pouyansab]

I am trying to connect 2 go direct devices to Pi3 using bluetooth. my bluetoothctl -v shows 5.63, but seems like the code only runs on 5.51. How can I return it to an older version or make the code work with the current? currently I'm getting the error below

Update: I was able to install 5.51, but now I'm getting the error below.

Likely resolved with v1.2.1 and the update to the latest Bleak.
