There are reason 22.

Thank you!

Hi, 

Disconnect reason 22 (0x16) means BLE_HCI_LOCAL_HOST_TERMINATED_CONNECTION. You can get also get BLE_HCI_LOCAL_HOST_TERMINATED_CONNECTION as the disconnect reason if a procedure timed out. For instance connection parameter update initiated by the slave, or other L2CAP procedure timeout or ATT related. It is difficult to say without knowing more. Some questions: 

• Can you also add the debug log here by adding DEBUG to your preprocessor definitions and provide the debug log from the device?
• Is it possible for you to share a sniffer trace showing this issue? 
• Which SoftDevice version are you using?
• What is the OS of your smartphone? Are you able to provide the log from nRF Connect?
