I want to send data from my Arduino UNO to esp-32 via serial connection. I connected an Arduino UNO to esp-32 via tx-rx pins. It works fine when the delay() is greater than or equal to 999. When it is less than 999, the value is not transferred to esp-32. Is there any to reduce the delay time?

Serial connection between ESP-32 and Arduino UNO
