Command	Description
`rssi`	Show RSSI and LQI of the last received frame.
`analyze`	Scan the current band (hopping) and report the strongest signal.
`jam`	Toggle continuous jamming on the selected frequency. Stop with `stop`.

Command	Description
`rx`	Toggle sniffer – prints every received packet in hex.
`rxraw <microseconds>`	Sample the radio at the given interval (µs) and print raw bytes.
`recsig`	Start recording fixed‑code remote signals for later replay.
`showbit`	Display the recording buffer as a binary bitstream.

Command	Description
`rec`	Toggle recording of complete packet payloads into the buffer.
`recraw <microseconds>`	Record raw OOK samples with the given sampling interval (µs).
`add <hex‑vals>`	Manually add a frame payload (max 64 hex bytes) to the buffer.
`addraw <hex‑vals>`	Manually add raw chunks (max 60 hex bytes) to the buffer.
`show`	Display all recorded frames (payloads).
`showraw`	Display recorded raw data.
`flush`	Clear the recording buffer.
`play <N>`	Replay frame `N` (or `0` for all frames) from the buffer.
`playraw <microseconds>`	Replay raw data with the specified sampling interval.
`playsig`	Replay the fixed‑code remote signal stored in the buffer.
