UART communication between Feather NRF52840 Express and Arduino UNO Post

[vatsal21770]

I am trying to achieve serial communication between Adafruit Feather NRF52840 Express board and Arduino UNO over hardware UART. I have connected TX and RX of both via logic level shifter as both the boards are working on different voltage. I am using adafruit_NRF52_Arduino and Arduino IDE to program. In Feather Express board While using Serial.write() and Serial.read(), I am able to write and read on Serial Monitor but I am not getting any data at Arduino UNO. Will this functions work or is there any other ways to do it? How to achieve UART with feather express and nrf52_Arduino library? Waiting for the response.
