I was wondering if we can send our messages to our own server directly (I mean HTTP POST/PUT)? How we can bypass the AllThingsTalk?
How we can use GET to receive a data? Any example?
What about downlink (realtime)? Does each shield have a public IP address to be able to send a message to the device? Or we need to implement something like MQTT (to poll the server every x seconds to see there is a message for device or not)?
Is there any carrier in Germany to support NB-IoT and the shield?
