Current architecture
The existing Nordic LTE-M demonstration connects an embedded STCP client to MQTT infrastructure through the protocol stack.
Secure publish/subscribe sessions for telemetry, command channels and long-lived device connectivity.
STCP can reduce connection-establishment overhead compared with a full TLS session in measured Linux tests.
The same Rust protocol core can protect MQTT across Linux and embedded targets.
TCP and UDP carriers allow deployment-specific tuning without changing application semantics.

Median and tail latency by payload size and network type.
Connect and reconnect costs for TCP, TLS and STCP.
CPU, memory and later power-consumption comparisons.
