Connecting ProMini and ESP8266 together via uart but not able to upload sketch

-

hello,

i'm looking idea how can solve issue uploading sketch pro mini , esp8266 via uart. both connected each other , send regularly data. when trying update 1 of 2 there interference because looks this
usb tx -> rx avr <- tx esp8266


one solution came mind pulling down reset of other board interfere transmission. if pushing manually reset button works. need trigger reset somehow during entire time when 1 of boards being updated.

how solve it? maybe possible pull pin high during bootloader receives new update?

reset low. connect reset pin ground.

it can't work both. esp usb connected rx-rx tx-tx
