Okay... It worked!!!
10th generation IPAD 16.3 VER IOS
SOLUTION HERE:
1. Make sure the apple pencil has some charge. ( give it 5 minutes to charge)
1.1 disconnect the apple pencil from a cable. Because in my solution it should work as a stand alone bluetooth device. The main problem is the cable connection to ipad.
So once pencile is charged( 5-6 minutes)
Simply disconnect it from charger.
Yes, you got me right, DO NOT CONNECT pencil with that cable TO YOUR IPAD, as this is the main reason why it won't pair ( hahaha)
2. Download lightblue app from app store.
3. Open lightblue app.( make sure pencil is not connected to ipad through a cable)
4. Search for apple pencil( should appear in the list)
5. Tap on apple pencil, then type 1234 for pairing code.( don't pair via regular bluetooth, it won't work)
6. Finally tap pair button ( it should work now)
Please notice!!!!!
On each pencil charge, or turning off the ipad, the pairing will be lost!!!
Solution for REPARING AGAIN:
0.1 connect the pencil with charge cable to wake it up ( with a time a pencil will enter the Idle mode.) so by connecting the pencil TO a charger will wake it up.
1.OPEN BLUETOOTH setting.
2. Locate apple pencil, and Tap on (I) sign to open THE dialog window.
3. Choose forget this device.
5. Open lightblue app again, and search for apple pencil again.
6. Enter 1234 for pairing again.
7. Bingo, it will pair your pencil and ipad again.
Reminder:
while pairing pencil, with ipad don't connect them with a cable!!!
Everytime you have a connectivity issues,
1. Forget device from regular bluetooth setting.
2. Reconnect your pencil again via light blue app.
3. Plug the pencil into the charger to wake it up.
Enjoy.
