  I wanted to turn wifi off on my board to check out how much memory it would release. Unfortunatly I trap into infinite trying to boot. Firstly I get:

  >ESP32.enableWifi(false)
  Erasing saved code.
  Done!

  I know that re-flashing helps to "fix" the board but I need t0 find a way to turn wifi off.
  I will be much thanksful for your advice.

• Why so little memory on board with ESP32

  @JumJum, hello again. I continued to search for answers, even have found ur 5 year old thread on esp32, where you state that:

  • ESP32.enableBLE(false/true) , adds about 1900 additional JsVars
    
  • ESP32.enableWifi/false/true) , adds about 3800 additional JsVars
    
    

  And I see that lots of people are talking about switching BLE off to get more free memory. But even 2500 jsVars is only ~35Kbytes, meanwhile my board advertises to have around more than 500 KBytes of ram. That's just nonsense!

  Reference page says that "E.getSizeOf() returns the number of variable blocks used by the supplied variable".
  But how should I estimate the real size of entities in my app? For example, E.getSizeOf(Number.MAX_VALUE) returns 1, meanwhile the bocksize is 14 (according to process.memory) and espruino numbers are 64bit. It just makes no sense for me.

  Sorry for asking kind of stupid question, but I really want to figure out how to calculate size of objects as preciese as possible. Thanks for answer in advance!

  Am I correct that exatly support of BLE & Wifi eats most of the memory?

  Hello everyone. I'm using ESP32 Wroom 32 devkit. It is advertised as having

  • Flash-memory: 448 Кb
    
  • SRAM-memory: 520 Kb
    BUT as I use process.memory(), I get quite confusing answer:
    Total of 2351 block * 14 bytes (blocksize) results in ~33Kbytes what is extremly low.
    Even if I made a mistake in calculations, I have seen with my own eyes how quickly I lose 2/3 of memory total memory after just a few requires(btw all files are minified) and launching a ws server with 2-3 connections.
    How do u think, can it be a problem with the firmware or Wifi + BLE modules take soo much memory?
