Kconfig (`menuconfig`)

Path: Component config → IOTMER.

Option	Purpose
`IOTMER_PROVISION_API_URL`	Base URL for provisioning (no trailing slash). Default `https://console.iotmer.com/api/v1`.
`IOTMER_PROVISION_AUTH_CODE`	API key sent as `iotmer-auth-code`. Empty + complete NVS session → HTTPS skipped.
`IOTMER_WORKSPACE_ID`	Workspace UUID in the JSON body; required when auth code is set.
`IOTMER_WORKSPACE_SLUG`	Optional override; production devices get `workspace_slug` from the provision API JSON and NVS. Use Kconfig only for testing or non-standard setups.
`IOTMER_TEMPLATE_ID`	Optional device template UUID.
`IOTMER_WIFI_SSID` / `IOTMER_WIFI_PASSWORD`	Station credentials.
`IOTMER_NVS_NAMESPACE`	NVS namespace for credentials (default `iotmer_creds`).
`IOTMER_PROVISION_TIMEOUT_MS`	HTTPS provision timeout.
`IOTMER_AUTO_OTA`	Enable HTTPS OTA when firmware metadata is present.
`IOTMER_OTA_APPLY_EVEN_IF_SAME_SHA`	Always OTA when URL+SHA present, even if SHA matches NVS (typical factory image).
`IOTMER_OTA_TIMEOUT_MS`	OTA download timeout.
`IOTMER_FIRMWARE_POLL`	Background task when firmware fields missing or OTA rejects image.
`IOTMER_FIRMWARE_POLL_*`	Interval, stack, priority for the poll task.

The mbedTLS certificate bundle and dual OTA partition table must match the target hardware (see example sdkconfig.defaults).

IOTMER BLE Wi‑Fi provisioning (optional component)

When the repository component iotmer_ble_wifi_prov is included in your project, its options appear under Component config → IOTMER BLE Wi‑Fi provisioning.

Symbol	Purpose
`CONFIG_IOTMER_BLE_WIFI_PROV`	When y, links the NimBLE GATT implementation; when n, stub APIs return `ESP_ERR_NOT_SUPPORTED` from the same component.
`CONFIG_IOTMER_BLE_ADV_TIMEOUT_MS`	Advertising duration while not connected (`0` = until `stop()`).
`CONFIG_IOTMER_BLE_CONN_IDLE_MS`	Connected idle timeout without qualifying writes.
`CONFIG_IOTMER_BLE_SESSION_MAX_MS`	Maximum session length after connect.
`CONFIG_IOTMER_BLE_ADV_NAME_PREFIX`	GAP name prefix (suffix is MAC-derived).
`CONFIG_IOTMER_BLE_RESTART_ADV_ON_DISCONNECT`	Resume advertising after disconnect while `start()` window is active.
`CONFIG_IOTMER_BLE_SMP_IO_CAP`	NimBLE SMP IO capability (`NO_IO` default).
