Transmit data (more than 1k) from core to phone app

[ScruffR]

I guess even in a new thread you won't get answers a lot different to mine in your other thread

@ScruffR

If you've got the possibility to reach your Core globally (e.g. DynDNS) you could have your Core run a TCPServer or even a Webduinio.
Or you could push the data to another server (via TCPClient) from where you'll pull it into your phone.There are some threads about that do deal with similar demands to yours - have a search

The answers of @harrisonhjones and @semaja2 do point you the same direction (port forwarding corresponds to globally reachable & intermediate server = push data to another server)
