I’m using MQTT interface to send multiple downlink frames.
My case is below.
/tx topic to send 3 downlink frames.
The first frame was sent. But there was no ack, so I received
/ack topic message with
Then I received
/error toplic messages with
"type":"DEVICE_QUEUE_ITEM_FCNT", "error":"invalid frame-couter" about next two downlink pending frames.
Is it a correct case?
I’m using LoRa App Server 1.0.1 and LoRa Server 1.0.0.
