ESP8266 doesnt wake up after put to deepsleep.

const char ssid = ""; const char password = ""; WiFiClient *client = new WiFiClient(); IPAddress clientIP = IPAddress(9xxx);

OneWire oneWire(5); DallasTemperature sensors(&oneWire); float temp1; unsigned czas; void work();

void loop(void) { delay(10); }

void work() { do { sensors.requestTemperatures(); temperatura1 = sensors.getTempCByIndex(0); } while (temperatura1 == 85 || temperatura1 == -127); sensors.requestTemperatures(); delay(500); temp1 = sensors.getTempCByIndex(0); String url = "example"; client->connect(clientIP, 80); client->println(url) client->flush(); client->stop(); delete client; ESP.deepSleep(10e6, WAKE_RF_DEFAULT); }

Problem: After a random time ESP doesnt wake up. [zombie mode on GPIO-0]

Conection: RST-> GPIO16

you're sure it is zombie mode and not wdt because it got stuck in "while (temperatura1 == 85 || temperatura1 == -127);" because of flakey sensor?

Does this: https://github.com/esp8266/Arduino/issues/6007#issuecomment-606414184 help at all? (47K pullup on MISO)

47K pullup on MISO solved this issue for me on ESP12F

I've been dealing with the zombie deep sleep wake up on my D1 mini clones. I went through that other thread in detail. I don't have any 47k resistors, but I put a 10K on MISO (pin D6 on the D1 -- this terminology is horrendous), but I still get the same failed wake up.

Does this work to wake up the ESP: https://github.com/esp8266/Arduino/issues/6007#issuecomment-542192213 ?
