Big ESP32 + SX127x topic part 3

Just by using the ESP32 Timer Deep sleep example

Specifically
esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP * uS_TO_S_FACTOR);
and using this line after a TX Complete
esp_deep_sleep_start();

Paul

edit: I am guessing the answer might be in using some of this but its a bit beyond my coding experience.
