Crate umshctl 

umshctl: the host tool for ULCP radio devices — inspection, device identity, persistence, pairing, radio configuration, and packet capture.

Every attach is administrative, with the non-resetting full-protocol handshake, so pointing this tool at an autonomously operating board never disturbs its configuration: only the command explicitly given changes anything.

With no command it opens a shell — one attach, many commands — which is worth a great deal over BLE, where each fresh attach costs a discovery pass plus a handshake.

Modules

App
