NodeMCU ESP-12F doesn't wake up
Posted: Fri Dec 23, 2016 3:43 pmHello. I'm new to this forum, and I came up here because I have a problem with my NodeMCU. The problem is that, when I put it in deep sleep mode, it doesn't wake up. The power consumption gets down (from 80 mA to 10 mA) in deep sleep and then a little up (20 mA), but it does nothing. On Serial Monitor, when it wakes up, appears the following:
--- EDIT ---
If I put Serial Monitor to 74880 baud, it prints the following:
My code is:
Moving code from functions to setup does nothing. And if I try to connect GPIO16 (D0) with RST, it resets constantly. Pulling-up D3 and D4 (GPIO0 and 2) and pulling-down GPIO15 doesn't work, either.
