If you're wondering: ESP8266 variant. Can't make the main thread go to sleep and wake it up on wifi events. You get to poll. Which doesn't work when you want power saving. Which I kind of do because I'm building a temperature sensor and 70mA constantly will warm it up.
It's really sad, because I implemented my entire application in 200 lines of code using all these wonderful pre-existing libraries, and now I have to rewrite it (which will probably be 2000 lines) because I hit a fundamental showstopper with power management.
I'm not familiar with the ESP8266, but it looks like wifi is disabled in sleep mode ?pic.twitter.com/m702OpD7zj
But it wakes up on the AP's DTIM interval. This is how Wi-Fi power saving works.
You can't do power saving on an esp in the way you want to. You should use 2 separate cores, the esp and an avr or similar that brings up the esp
Yes I can. There's even a whole document from Espressif about that. https://www.espressif.com/sites/default/files/9b-esp8266-low_power_solutions_en_0.pdf …
I HIGHLY recommend you talk to the ESP WIZARD @cnlohr, the man works MAGIC
https://github.com/esp8266/Arduino/issues/1381 … ? any issues with this thread? Keep in mind it is only possible to enter sleep modes if you are connected to an infrastructure. APs need to _always_ be listening :(
It is not sad
It is showing you that you need more adequate control of our device
As you said, "because the design choices are fundamentally stupid and broken." Regardless what their #duino marketing says and does
