Open-source IoT Gateway - integrates devices connected to legacy and third-party systems with ThingsBoard IoT Platform using Modbus, CAN bus, BACnet, BLE, OPC-UA, MQTT, ODBC and REST protocols
Describe the issue
First of all, sorry, for asking here instead of at the thingsboard-python-cliend-sdk project. But my question is about gateway API so I decided it put here.
Here is official example how to listen to shared attributes updates. And there said that it is obligatory to send connect event for a target device (in our case it is a LoRa sensor).
# without device connection it is impossible to get any messages
gateway.gw_connect_device("ImageTest")
We do that in our C project on ESP board. But we noticed that after some time server "forgets" about our ESP gateway or about a target device, thus the gateway doesn't receive updates of shared attributes of a target device. There is no session errors, no reconnections and moreover the gateway pushes every minute its own telemetry and each hour the telemetry of a target device.
So my question is how often the gateway should send connect event to a server about a target device?
