ESP32 S2 and MAX6675

Hi, I'm using an ESP32 S2 Solo with the thermocouple MAX6675. I'm working in a temperature read project where I activate the deep-sleep, I read the temperature and I go back to the deep sleep. I have to try to save the most battery I can, so the time that the module is in an active mode must be the smallest.
After searching a lot of information, I'm not able to read the temperature after waking-up from deep-sleep. Does anyone know why?

I want to do the project without using delay's, to reduce the time. If I use a 500 miliseconds delay, it works well, but using a delay it's not my purpose.

I have an ESP32 WROOM Devkit and here there is not any problem, I mean, I can wake up, read the temperature and go to sleep in 50 miliseconds.

If someone can help me, just let me know how.
Thanks.
