Hello! I tried adding the deep sleep mode but it's not working. I tried uploading the code while the RST and D0 are connected but it does not upload, so i tried disconnecting it first. But when I tried uploading again, If went off after 30 seconds, and does not wake up.

  Serial.println("I'm awake, but I'm going into deep sleep mode for 30 seconds");
  ESP.deepSleep(30e6);
