Hello community,
Is there a way without MQTT to prevent an ESP 8266 from deep sleeping until it has established an API or WiFi connection?
So: ESP On => Check Wifi => connection ok => send values => go to deep sleep or
ESP On => Check Wifi => connection faulty => stay online until connection established => send values => go to deep sleep
I can’t figure it out from the forum entries and the documentation, as they all refer to MQTT.
Thanks for the help
