camera not ready

Error message

camera not ready

What it means

Connect stops any existing camera preview before starting a new one, retrying StopCameraPreview up to 5 iterations (1s apart). If after 5 attempts the camera still cannot be stopped/prepared, it returns "camera not ready".

Solutions

1. Ensure no other session is streaming from the camera before connecting
2. Power-cycle / restart the robot or camera device
3. Wait and retry Connect after a few seconds
4. Check the device is online in the Roborock app and not in DND mode

Example fix

// before
err := client.Connect(ctx) // "camera not ready"
// after
if err != nil && err.Error() == "camera not ready" {
    time.Sleep(10 * time.Second)
    err = client.Connect(ctx) // retry after device frees up
}

// check device availability before Connect
if !isDeviceOnline(deviceID) || isOtherStreamActive(deviceID) {
    return errors.New("camera busy or offline; retry later")
}

err := client.Connect(ctx)
if err != nil && err.Error() == "camera not ready" {
    time.Sleep(10 * time.Second)
    err = client.Connect(ctx) // bounded retry
}

When it happens

Trigger: Calling Connect (directly or via Dial/Start) when the roborock camera stays busy — StopCameraPreview keeps failing or the device never becomes free within the 5-second window.

Common situations: Another client/app is actively streaming from the camera; the robot vacuum is offline or in Do-Not-Disturb; lingering previous session on the device.
