This all depends on the classes supported by your device. When your device supports Class-C, you can send data right away-ish (it will be enqueued, but the LoRa Server scheduler will send it asap to the gateway).
Please refer to the LoRaWAN specification for the differences between Class-A / Class-B and Class-C.
The device is a C-class, but i’m not sure my data is going out, also is it possible to send via Fport 0.
When i do the tx with mqtt i get a ack on the device live view, but only when i use “application/9/node/xxxxxxxxxxx/tx” and not “application/9/device/xxxxxxxxxxx/tx”?
This is not possible, per LoRaWAN specification. fPort 0 is used by the network-server.
