BlueZ 5.50: Avoid service discovery in every connection

[Miguel Sancho <miguel.a.sancho@xxxxxxxxx>]

Hi,
using Bluez 5.50 to pair do a BLE device, I am seeing that there is
Service Discovery every time the peripheral is connected:
ReadRequest
ReadRequest
....
Read By Group Type Request
Read By Group Type Request
Read By Group Type Request
...
This behavior continues even if the remote device is marked as trusted.
how can this be avoided?
Thanks in advance
Miguel
