Hi,
My HW setup has ESP-12 module, LM75 tempsensor and three LED indicators connected to GPIOs.
ESP reads the temperature sensor and sends the value to a server once a minute triggerd by tmr.alarm. The module is warming the board and the temperature of the sensor is about 15 deg C higher than room temperature.
I can't use dsleep since one of the LEDs should be on all the time. I have tried wifi.sleeptype and node.dsleep(nil,4) to turn off the radio, but they don't have any effect on current consumption. node.dsleep(1,4) resets the module and the information of which LED is on is gone.
Any ideas how to go a low(er) power mode during waiting for next measurement and keep the gpios on?
Timo
