I wanted to upgrade the firmware of one of our parking sensors.
When I am installing the new firmware, the RX LED is flashing rapidly but the TX LED is off.
I cannot read nor update the configuration.
I can configure and update other parking sensors. So I think the hardwre of the parking slot is dead.

We bought this parking sensor. Its SN is 001AF3ED.

What can we do?

Please help.
Thanks!

I didn't find the right solution from the Internet.
