Re: low ambient temperature - no boot ( bug or future )

I think it is probably related to some tollerances of the oscillator components (quartz, capacitors) that leads to some instability but would be good to get a feedback from espressif. Seems pretty stable "bug" and affected only at boot time. While chip work, outside temperature -20 degrees of Celsi...

Re: substract 32 from uint8 temperature_sensor_read()

According to specifications, temperature sensor work from -40 to +125. Return value of temperature_sensor_read function is unsigned. So you need substract 40 from returned value to get valid results ;) Also, to convert from Fahrenheit to Celsius, you need substract 32 and multiply by 5/9. uint8 tRaw...
