Hello
Thank for your reply.
In my point of view
the node did not actually transmit
If the problem occured to one of them, may be. But all nodes, in the same time were not seen by the gateway with no transmission. I do not thinks, it’s the problem (i think, but may be I am wrong)
the gateway did not receive a valid raw packet
I do not think, as well, as the package were successfully sent for one moth, and at the same time there were no trasnmission for all of the nodes. Or may be I do not understand your suggestion
the gateway did not communicate it to TTN servers
May be but why there is traffic on my gateway (other than my nodes). I can not see traffic for my nodes
the TTN servers are not working
How can I check it? and why this issue append for now more tna 2 days. It’s a long delay for an interruption of service, isn’t? TTN should not inform this?
the packet is invalid because it is a repeat of a used sequence number
I do not understand what you means. May be a lack of knowledge from me
the packet is invalid because it has the wrong keys
What do you means by keys? Network Session Key and App Session Key
Do you means the variable where are store the key could be corrupt or somethings else?
But as the 4 nodes are independent of each other, how can you explain that the key are wrong for all nodes at a point of time
Or do you means the gateway key? The gateway key is not store in the nodes and the gateway is seen at TTN console
What is interesting to observe, the gateway is usually seen each 15 second (‘last seen’ field of the gateway overview tab). Actually, the ‘last seen’ field show 3 minutes. In fact, it display 3 minute, 2 minute, 3 minute, 2minute. It never go the 1 second. Previously, I observed this value in seond: 12s, 9s 12s etc.
It’s look like now, the gateway is seen each 2/3 minutes. Is not long 2-3 minutes?
