I’m running the Chirpstack Docker installation and using it to talk to simulated devices. The simulated devices can join and send data and all appears to work as it should.
Using the gRPC interface I’m trying to send an unconfirmed message to the simulated device. The message enqueues correctly and sends when the device send data up. I can see the command is received by the simulated device. The problem is that the message is not cleared from the message queue and it is sent every time the device uploads data. I have to flush the queue to remove the message.
The same happens on the web interface on the panel where you can Enqueue downlink payload. If I don’t tick the confirmed downlink option the message will remain on the queue until manually cleared.
In this link, No downlink visible in Live Loraframes, brocaar says
ChirpStack will only consider a downlink as transmitted when it receives an acknowledgement from the gateway. Really old packet-forwarder versions did not send back these acknowledgements. You could validate this in the ChirpStack Gateway Bridge if any tx ack was received from the gateway.
Is there anyway to simulate the gateway acknowledgement on a docker installation? Or some other way to tell when a message has been sent.
Or have I made some other neophyte mistake?
I don’t currently have access to the hardware, it is sitting at work and I’m in covid lockdown 90 minutes away.
Thanks in advance
