tmr.delay(), delay I meant in general - to put delay between doing tasks and for sure non-blocking, using
tmrin this manner:
tmr.create():alarm(10, tmr.ALARM_SINGLE, function(t_ads) adc1:startread(function(volt). Saying “not optimal” I meant that usually, when you have device library it should do these small tasks and you should be free of thining about “did I forgot to put delay between readouts”. I will do readings today using different timing and will return with results.

@tjakober What are your .h changes. I just used linux x64 w/o issue on default...

I showed the head ref, too just in case something was fixed before I posted.
Yeouch. I was just looking at 'smartconfig.' Man is it ugly for security, even using AES. In the situation where you are a company and you have pre-provisioned your devices with specific AES keys to deliver to the public customer, those keys live on the device. We all know how to dump the storage, find the programs, perform disassembly or whatever is needed to find the keys. Now after they are publicly shared some war driver can capture your packets (or your neighbor can do the same) and your network is passphrase is known. Even without capturing the AES key, an attacker can drop a device with battery to capture the info of the target. The device can then get on the network transmit its passphrase to "destination hosts somewhere belonging to 'chchchoo' (sorry had to sneeze) the attacker." The device erases itself to avoid detection or maybe reconfigures itself for some rapid or stealthy recon. It could just alter the key to send you on a fools errand when doing your response effort to figure out what someone did. Basically smartconfig will unwittingly put the networks of your customers at risk -- or your personal network if you use it yourself.
No matter what, good security practices indicate that you should pay attention to what hosts are on your network -- or use good provisioning techniques that meet your risk threshold for your Intellectual Property (which may or may not include smartconfig). I don't use it.
#define WRITE_BLOCKSIZE 2048. Now is it set to 2KB for memory issues? Each time the 2KB write happens the esp should read the full block, update it, then write it. So writing with 2KB means double the reads and double the writes for each write. Correct?? I know this routine should rarely be used but I'm just curious about the reason for 2KB rather than 4KB.
The Makefile definitely does not work on wsl. I made now a VM with Ubuntu and there it will compile to some extent. However also there I have a missing file:
In file included from /home/thomas/nodemcu-firmware-esp32/components/luac_cross/../lua/lua.h:18:0,

modules/in the flash file system and at boot time inject
modules/*.sointo the firmware memory? (I'd like it to ignore subdirs, reasons on demand.)
