bootloader sounds nice, how its going?
Ivan Grokhotkov
@igrr
good. I've simplified it a lot, compared to the one from espressif and rboot. just one segment of code, no .data and .rodata, no extra build step for extracting the code like in rboot. almost ready to merge...
Markus
@Links2004
sounds good
Ivan Grokhotkov
@igrr
right now it just loads the app, nothing more, but then it will be just a few lines of code to add OTA
also now we need to flash just one binary, it is not split into two parts
so this simplifies memory layout and "size used by the sketch" calculation
Markus
@Links2004
but this will also mean all code is forced to flash? and we loos the option to put some functions in ram?
Ivan Grokhotkov
@igrr
no the iram segment is still there. it just follows the irom0 now
because it doesn't matter where it will be located in flash — it will be copied into ram anyway
so the bootloader skips over irom0 and loads three other segments
Markus
@Links2004
ok, will take a look when its done :)

a few days ago, this image was loaded here https://files.gitter.im/esp8266/Arduino/Lqkg/SPIFFS_WebServer.png
what are all the screens (what is the esp editor)??

@igrr, thanks for your reply, after sending my last message here and going to sleep (this must be the biggest problem, not enough sleeping time :-)), it made sense to change the only things I didn't changed before - the AP and the PC. I just made a quick test this morning and the access from a Linux device (other router running OpenWRT that I have in my network) gave me very good ping results (always below 5ms, no losses), and using my android phone browser gave me consistent access to the web pages on the ESP webserver, without long timeouts as I observed with my PC. I don't have time now to make deeper tests, I will try to make additional tests later today using the same PC with Linux instead of Windows, to check if this is a hardware or software problem with the PC, but it seems that the ESP is OK! :-) So, sorry for all the 'noise' here, the problem seems to not be related with the ESP nor with the Arduino framework for the ESP.

@igrr
great! :)

@alon24 it was an example I had created and loaded while we had spiffs. When we have spiffs again, probably the example will be there also. What you see, runs on the ESP from SPIFFS.

@IanWalker
Including the ESP Editor screen ? What exactly is the function of that?
ficeto
@ficeto
Its a small webpage for managing the files on spiffs. Similar thing should be in the SD server example
Ivan Grokhotkov
@igrr
you can run the same from an SD card right now by the way

@chadouming
Ok, so that bootloader thing, it sounds amazing

@ficeto
I got my DSO yesterday and gotto look at some I2C pulses last night
the best pullup seems to be the 1K resistor
gave the closest to sqware pulses
today I plan to see why the ssd13.. fails when lots is going on
Ivan Grokhotkov
@igrr
which model did you get?
ficeto
@ficeto
DQ5202 ... they all the same... :D
this one is the 200MHz version
chad cormier roussel
@chadouming
I can have access to a professionnal oscilloscope if you need test to be made
ficeto
@ficeto

@chadouming we would need it if someone wants to investigate the radio. Which would be really cool...
Markus
@Links2004
i have access to an network analyzer at work, if some to test with tell me.

@ficeto
yeah :) mine is a shitty chineese DSO that I imagine costs a fraction of what those cost
unfortuantelly I have no clue how to use network analizer..
Markus
@Links2004
in basic it shows the raw "data" of the frequencies in the air. like an oscilloscope for radio.
ficeto
@ficeto
a good use for it is to see what power actually comes out of our modules
Markus
@Links2004
yes for example
ficeto
@ficeto
with the different antennas and settings
as we are not yet managing those
i saw a youtube video with a guy that had 300+ meters range with the trace antennas
Markus
@Links2004
free line?
ficeto
@ficeto
yup
Markus
@Links2004
and may not in the city to many noise therer
ficeto
@ficeto
netgear router on the other end
they were on a highway
it was rural but not that much
the other amazing thing is that he used an antenna from a router on another module
and got close to 500 meters
and using a directional mimo adapter, he got 3km +!
