# espos_sk SignalK: mDNS discovery, access token, delta stream in and out. ```sh idf.py add-dependency "signalk-espos/espos_sk^0.7" ``` Part of [espOS](https://github.com/signalk-espOS/espOS), an ESP-IDF runtime for Signal K devices. The components are released in lockstep, so one version of `espos_sk` works with the same version of every other. **Documentation:** [docs/signalk.md](https://github.com/signalk-espOS/espOS/blob/main/docs/signalk.md) **Examples:** * [`analog_input`](https://github.com/signalk-espOS/espOS/tree/main/components/espos_sk/examples/analog_input) * [`digital_switch`](https://github.com/signalk-espOS/espOS/tree/main/components/espos_sk/examples/digital_switch) * [`json_and_meta`](https://github.com/signalk-espOS/espOS/tree/main/components/espos_sk/examples/json_and_meta) * [`listener_relay`](https://github.com/signalk-espOS/espOS/tree/main/components/espos_sk/examples/listener_relay) * [`pulse_counter`](https://github.com/signalk-espOS/espOS/tree/main/components/espos_sk/examples/pulse_counter) * [`tls_server`](https://github.com/signalk-espOS/espOS/tree/main/components/espos_sk/examples/tls_server) Built on the espOS tree as a git submodule, or installed from the registry; either way `REQUIRES espos_sk` in a component's `CMakeLists.txt` resolves it.
