"Boost" mode in ESP8266 where the CPU or base clock is doubled (I know the CPU can do it) and WLAN is temporary suspended.

That's already in ESP32?

I noted when switching to the current v3 SDK: - user_rf_pre_init is NO LONGER called (contrary what is said above). You can set a variable in your function and check it later to see. - user_rf_cal_sector_set is NO LONGER called (contrary what is said above). You can set a variable in your function a...

Or even better: just, public (!) confirmation from Espressif (or adjustments of course).

I am sharing my experiences about this here. I really hope some of the Espressif employees will step in and comment. Otherwise it may serve as starting point for others that have the same question. BTW this is all non-OS SDK. To start with, during the very early boot process, some functions in user ...

Totally understood ;) I already guessed that would be the way to go if nobody could give me this information (either because unknown or because classified (for some stupid reason)). I'd simply allocate some growing array on the stack though, rather than having a function recurse on itself. Issue is ...

If you make any delay long enough, wifi will break anyway. I don't think you should use them, use timers instead.

Hi Pratik, Good to see you're still around here ;) You say this: The DRAM is actually 96kB. With nonOS SDK, the remaining 16kB gets used for ROM code. In RTOS SDK, you have the entire 96kB for data, bss, rodata and heap. Because heap is the flexible one here, it depends on the size of (data+bss+roda...

Hello All, This has been puzzling me more and more lately and I don't seem to find out anything about it (googled it...) According to https://github.com/esp8266/esp8266-wiki/wiki/Memory-Map: 3FFFC000h 4000h RAM ETS system data RAM. 3FFE8000h 14000h RAM RW User data RAM. Available to applications. In...

The link doesn't give much information. Is this an USB-serial converter (like CP2102) and some connectors added?

What ESP's can fit out of the box? I need ESP01 and ESP201.
