"A connection is required for write operations" error

When I tried to write value to the monitored item using the OPC UA Clint for Android, error popup saying that “A connection is required for write operations”.
I can see the current value of the item updated successfully when modifying the value at the server side.
When updating the value at server side, I use the sample console client program running on the same machine.

Test environment:
– Console client program : Evaluation version 2.1.0-436
– Java for Android : OPC UA Client v2.0.1

What is the possible reason of this?

Sounds a bit strange. The connection can be often flaky, but if you get subscription data, also writes should work. Is this a constant problem or only occasional?

It is constant problem.
I tried another Android program, which writes successfully.

When comparing two protocol frames using wireshark, there’s no WriteRequest/WriteResponse on Prosys.

Protocol summary of the two apps are;

1. ProSys Android (Frame 1 – Frame 159)
==================================
– CreateSessionRequest/Response (Frame 20/27)
– ActivateSessionRequest/Response (Frame 28/29)
– CreateSubscriptionRequest/Response (Frame 42/43)
– CreateMonitoredItemsRequest/Response (Frame 44/45)
– CreateMonitoredItemsRequest/Response (Frame 114/115)
Frown write value error here Frown
– CloseSessionRequest/Response (156/158)

2. Another Android Program (Frame 1 – Frame 86)
========================================
– CreateSessionRequest/Response (Frame 18/25)
– ActivateSessionRequest/Response (Frame 26/27)
– CreateSubscriptionRequest/Response (Frame 30/31)
– SetPublishingModeRequest/Response (Frame 32/33)
– CreateMonitoredItemsRequest/Response (Frame 56/57)
– Smile WriteRequest/Response (70/71) Smile
– DeleteSubscriptionsRequest/Response (81/82)
– CloseSessionRequest/Response (83/85)

Below is the detail frames for two programs.
