Hi Orne,
I have a problem sending downlink confirmed messages to any node, since every time I receive an ACK on the MQTT queue ending by /ack the “acknowledged” field is always set to “false” although the message is actually received by the node and the server receives a positive ack from it, since in the device log I see “ack: true” in the ACK message.
The node are in class C OTAA and the server a 2.x version.
Here’s a few messages read from the MQTT queues:
{“applicationID”:“1”,“applicationName”:“Urbana-retrofitter”,“deviceName”:“S1804600004”,“devEUI”:“70b3d58ff0035f0d”,“acknowledged”:false,“fCnt”:786}
{“applicationID”:“1”,“applicationName”:“Urbana-retrofitter”,“deviceName”:“S1804600004”,“devEUI”:“70b3d58ff0035f0d”,“rxInfo”:[{“gatewayID”:“aa555a0000000107”,“name”:“Gewiss-pilot”,“rssi”:-103,“loRaSNR”:6.8,“location”:{“latitude”:0,“longitude”:0,“altitude”:0}}],“txInfo”:{“frequency”:868100000,“dr”:5},“adr”:true,“fCnt”:3539,“fPort”:2,“data”:null}
And here’s the log of the Lora-App-Server:

I hope you can clarify this issue, since I need to retrieve the actual acknowledgement status asap.
Thanks.
