When tfmini is enabled, buzzer cries continuously

Dear members
When I enable SENS_EN_TFMINI and reboot PX4 (1.8.2 Stable Ver.), I come to hear the buzzer
ring contiuously. I’m using Pixhawk2. I attach the capture in Mavlink Console. Of course I reconfirmed the wiring esp. TX-RX.
Thank you for your kind advice in advance.
