We have completed product development using TLSR8253 and are currently mass-producing. I got a lot of help. Thank you.

This time, I would like to use BLE to control the lock/UNLOCK of the vehicle door.

In general, we already know that the RSSI of BLE has a large measurement error rate.
However, we have to use BLE or Bluetooth due to the customer's request. Do you have any recommendations?
