# nsx-cordio

<!-- nsx:facts -->
Optional Cordio/WSF Bluetooth LE host stack. Vendors the AmbiqSuite third_party Cordio stack (ble-host + ble-profiles + WSF) at AmbiqSuite stable-2026.06.18 (caaf5af860) plus NSX edits, and builds it from source for the active SoC's BLE transport. Low-level stack only; the app-facing convenience API lives in nsx-ble.

- Type: Backend specific
- Version: 5.2.26
- Project: nsx-ambiq-sdk
- Revision: v5.2.26
- Source: https://github.com/AmbiqAI/nsx-ambiq-sdk/tree/v5.2.26
- Capabilities: bluetooth_le, cordio, wsf, ble_host_stack, sdk_component
<!-- /nsx:facts -->

## Add it to an app

```bash
nsx module add nsx-cordio
```

## Capabilities

- bluetooth_le
- cordio
- wsf
- ble_host_stack
- sdk_component

## Use cases

- provide the Cordio BLE host stack (HCI/DM/L2CAP/ATT/SMP/GATT) to higher-level BLE modules
- build the WSF FreeRTOS port for the active SoC
- supply the SoC-specific BLE HCI transport driver (Cooper on Apollo4P, integrated BLE on Apollo3/Apollo3P, EM9305 on Apollo510B)

## Requires

- [`nsx-ambiqsuite`](https://ambiqai.github.io/neuralspotx/modules/nsx-ambiqsuite/)
- [`nsx-ambiq-hal`](https://ambiqai.github.io/neuralspotx/modules/nsx-ambiq-hal/)
- [`nsx-ambiq-bsp`](https://ambiqai.github.io/neuralspotx/modules/nsx-ambiq-bsp/)
- [`nsx-freertos`](https://ambiqai.github.io/neuralspotx/modules/nsx-freertos/)
