ABP join does not transmit and receive any data, it just changes some data structures in the stack which will (almost) always succeed.
For OTAA your device sends data which has to be received by at least one gateway and TTN needs to respond to that using one of those gateways which has to be received by your device.

Is there a gateway near to you? Do you see anything being received in the TTN console for your device?

data send to my gateway beside me
this pictures are device console and gateway console

If this is your node and gateway and they are 5-10m apart with a brick wall in between. And you RSSI is at -111, I would think there is something wrong with your antennas.

Tell us more about your setup, where is your node and where is the gateway? Close proximity, far apart, building in between…

Please read the many many many messages on this forum regarding devices shouting to a gateway. LoRaWAN is LOng RAnge technology and won’t work (reliably) when device and gateway are close together. It is like you trying to understand what someone is shouting next to your ear in a quiet room…

gateway and end device are 20cm far from each other
but i didnt connect antena
now its connected and rssi is better but still the problem exsist

thank you my friend

This is the one of fastest you can make RF devise stopping to work, it is like reversing VCC and G.
