So to summarise it is an issue and there are what I see as 3 solution.
- Keep the web socket Connections permanent open. - consumes resources.
- Action by TTI on TTN Servers.
- Keep sending traffic to node say every 20 seconds with short payload.This seem wasteful in air time and on TTN server resources but is the only option open to gateway / node owners.This is easy to set up with a spare node.
- TTI Change server software to take account of the disconnect of web socket in regard to handling down links and intersection to the TTIG.- Action by TTI.
I hope TTI looks seriously at this issue and resolve it as it causes issues with ADR and Acknowledge responses and packet loss. To have all of the TTIG owner sending dummy traffic to keep gateway open is very wasteful on TTN.
Related to above when will there be update software for TTIG?
