As of February 10, 2020, the new BLE function of the LIFF app will no longer be provided in the LINE Things Developer Trial when creating a new app.
Now, the LINE Things Developer Trial will only offer automatic communication.
The LINE Things Developer Trial does not plan to provide the BLE function of the LIFF app again.
We apologize for any inconvenience this may have caused. LINE will continue to improve the quality of its services to its customers. Thank you for your understanding.
