Notifications disconnected after 60 seconds

[kevinchapron]

Hi,

I did a peripheral program with a NRF52 working perfectly.
I did a central program receiving data from the NRF with "github.com/currantlabs/ble" as library
When i suscribe to a characteristic, the program seems to stop itself (disconnecting) after 60 seconds every time.

First i thought it was my code, but i tested with an example of "github.com/getsenic/gatt-python", and it works perfectly indefinitely
So, my question is : how is it possible to receive more than 60 seconds of data ?

I join you an of the program running (on the central program, being run on a Raspberry Pi 3).
