Blynk mobile app stops sending commands to device . #572

Closed sonirohit3 closed 1 year ago

sonirohit3 commented 1 year ago

Blynk library version: [0.6.1 / 1.1.0 ] IDE: Arduino IDE version: 1.8.19 ESP32 core : 2.0.3 Board type: ESP32 DEV BOARD Additional modules: none Server : 0.41.17

Scenario, steps to reproduce

This is a Home automation board where we need to control relays using local server.

Expected Result

Actual Result

The initial connection is fine and shall work for around 30 mins to an hour.( this is totally random) After that we can see that the parameters are updated on mobile app like LCD, button colours etc from device side but when anything is triggered from mobile app like button action etc, the device won't respond. In-fact the Blynk.run() and Blynk.connected() always return true at that time. Also one more behaviour, if somehow Blynk get's disconnected from server, it won't connect again until and unless the device is reboot. This won't reconnect even if wifi is reconnected again. How to debug this issue? I have tried both Blynk library but same issue. The server version is 0.41.17
