Hi i am using unowifi R3 Atmega328p board and esp8266 inbuild in the board i have flashed new firmware in the board and i am able to get replya of at command ATATRST and ATGMR is working but rest Command are not working. And guidance will be helpfull. The power is on and I can see the power led indicator lit this is plugged directly into the wall.

I looked at my board and saw that it was NodeMCU V3 and that the seller had labelled it as NodeMCU V3 ESP. 2espcomm_sync failed や espcomm_open failed エラーが出る. When GPIO0 is set to low the ESP will go to boot mode on next reset.
