I have a weird behaviour with my board ESP8266 ESP-1. The board after power only startup if I join the pin #3(CH_PD) and pin #5(Reset), if I leave both in up level and the whole combinations (obviously in line with the pin characteristics), the board doesn't startup.
I've followed the indications in the datasheet and youtube videos, and I've 4 boards and all of them have the same characteristics.
Some suggestions are welcome.
