I usually configure my Multitech gateway on eth0 with the sim card in failover mode. But i was wondering if it’s possible to set up a buffer on the gateway in case of connection lost. I am not asking how to configure the gateway but i would know if there’s no technical limitation with mqtt and chirpstack if the gateway forward previous IOT data to the server.
Both the Gateway Bridge and the MQTT Forwarder support queueing messages when disconnected, if they’re a.) run on the gateway and b.) configured with QoS set to 1 (or higher, but 1 recommended).
Thanks for the answer. I get what Qos is , but for me it’s more an ack if some paquets are missing. But i d like to know what happens if i lost internet during like 10 minutes. Because i guess that any gateway will store all the iot data during these 10 minutes and send them back to the server when the connection is back
I have the same question here. How can we store the measurements in case of failure of the gateway? I was thinking about a kind of ring buffer deployed in the ESP32 device itself, but I never thought about doing that kind of thing in the gateway realm.
