I have a ESP8266-12F setup to send data to thingspeak. It connects to my AP and does a http post to a rest service where it stores the measured light intensity and the battery voltage. That looks like this:



It does an update every minute. Between updates it goes in deep sleep mode. After a one minute timeout it wakes up and reboots and does a new post. But it sometimes seems to miss one or more updates. I have no idea if it simply doesn't wake up from the sleep cycle, if it is unable to connect to the AP or if the webservice refuses connection. Does anyone else have the same problem?

what is your schematic ?

I have the same problem with my ESP-01 but I think this is because GP0 and GP2 aren't in the right status during the reset!

Maybe have a look with this idea

If you are using EasyIoT Cloud and MQTT: we added security feature - if there are too many login attempts with incorrect password your IP address is banned for some period of time and you are unable to connect to EasyIoT Cloud.
