NodeMCU flashing sketch problem

[febalci]

When openlog connection is done with UART0 (RX,TX pins, GPIO1 and GPIO3) of NodeMCU 1.0, there's no way to flash new sketch to Nodemcu, i have to take out TX pin of NodeMCU out every time. When i make serial.swap to D7 and D8, then Serial monitor of Arduino IDE is not working. When i use Serial1 TXD1 (D4, GPIO 2) then there is no RXD1. How can i use TX and RX pins with allowing new sketch flash of Nodemcu?
