I have B-L072Z-LRWAN1 board from ST running I-CUBE-LRWAN software for LoRaWAN, and RHF0M301 gateway from RisingHF.
I am testing a class C and I have an issue in downlink, here is the scenario:
- Node transmit an uplink to server, then a delay for 30s to transmit the next packet.
- During that time I send a packet from server, it is received by gateway ( INFO: [down] a packet will be sent in “immediate” mode)
- But it is not sent to node immediately, node receives the packet before the timeout, then process the next uplink immediately. (For example, at 28s it receives the packet, at 30s it process the next uplink)
So, what is the reason of this problem? How can I solve it?
In my viewpoint, It could be caused by the gateway (no immediate transmit), or configurations in node.
