i need to connect my phone to the esp32 with BLE(Bluetooth Low Energy). But only when you are close to just 1 meters. So, how can i reduce the meters? And also if you go far away from 1 meter, it has to disconnect. I would be happy, if you answer...

Unfortunately this would be very challenging to implement because you have to rely on the RSSI to approximate the distance which is not always very reliable. Have a look at these links below for more information:-

Connect if the RSSI more than 40 and keep updating the RSSI for 2 seconds, get the average if it's more than -30 then you're too close to the device.
