Hi everyone,
I bought one LoRaWan Gateway model RAK7289CV2(Firmware WisGateOS_2.2.10_RAK). I tried to use the Built in network server work mode that already implemented inside gateway. I encountered the issue when I tried to push a downlink command from MQTT to a note via gateway.
This is my configuration for Gateway.
Our node joined the network server with OTAA mode and Class A.
I published the downlink command to a device with payload size is 15 bytes.
This cmd had been put into a queue until the node sent a uplink.
But after the node sent a uplink to gateway with DR2 successfully, the gateway didn’t send the downlink to the node. I checked system log and I saw:
“daemon.err lorawan[26502]: lwDataDownComplete: 02216910 Device AppDataSize 15 > MaxPayloadSize 11 (DR2), drop dl message”.
After that the node tried to send another uplink with higher datarate (DR5) but it didn’t receive the downlink anymore.
I think it related to the dwell time (400ms) of region AS923.
Then I tried to disable the Downlink Dwell Time Limit configuration, but it still not work.
Please help me resolve it.
Thanks and Regards,
Phong Le
