can't come up with answer without some serious thinking. Surely takes less to give it a go :P

hehe - indeed. but first comes lunch! :-P

@martinayotte
@everslick , I'm using Wire on GPIO0/GPIO2 without any issue for more than a year.
Clemens Kirchgatterer
@everslick
hmm, i have my own bitbanging code. maybe Wire does something to switch of serial?
Martin Ayotte
@martinayotte
it is doing pinMode(GPIOx, INPUT_PULLUP) right at the beginning.
Clemens Kirchgatterer
@everslick
yeah, but it does not switch off any debugging output in the core neither.
@martinayotte do you have SDA or CLK on GPIO2 ?
Martin Ayotte
@martinayotte
According to my sketch and wiring, I'm doing Wire.begin(0, 2), so it is wired as SDA=GPIO0 and SCL=GPIO2.
Both with external pullups.
About debug output, I'm pretty sure it is turned off by the pinMode()
Clemens Kirchgatterer
@everslick
that could be
do you have a button on GPIO0 as well?
Clemens Kirchgatterer
@everslick
testing with 2 and 4...
Martin Ayotte
@martinayotte
But the button on GPIO0 isn't pressed for normal use, and almost never since I'm using OTA since months.
Clemens Kirchgatterer
@everslick
ic. i use the GPIO0 for factory reset and debugging, so when i press it short i see a dump of debug messages, if i hold it for 5 seconds, the device factory resets (clears eprom).
so i wonder, if this will conflict with I2C
Clemens Kirchgatterer
@everslick
argl. it works.
even with shared SPI bus
and i don't have any idea why it did not before.
Martin Ayotte
@martinayotte
Great !
Clemens Kirchgatterer
@everslick
thx, for your help though! always appriciated!

I'm having issues finding mDNS entries for my ESP8266. I'm using https://chrome.google.com/webstore/detail/mdns-browser/kipighjpklofchgbdgclfaoccdlghidp and can't get anything to show up after I've added a service.
for instance:
/* Setup DNS-SD */
    if (MDNS.begin("esp8266")) {
        MDNS.addService("e131", "udp", E131_DEFAULT_PORT);
        MDNS.addService("http", "tcp", HTTP_PORT);
    } else {
        LOG_PORT.println(F("** Error setting up MDNS responder **"));
    }
it sets up just fine, and i can make mDNS queries for other devices from it, but I can't see my own services
Shelby Merrick
@forkineye
I can use MDNS.queryService and see other devices / services on my network, but can't get my esp's to show up at all

@me-no-dev
interesting... I see the arduino service, but not the web
Shelby Merrick
@forkineye
what sketch you using?
or is that the updater service?
Me No Dev
@me-no-dev
how does sketch matter :)
I haave web server, added a service
Shelby Merrick
@forkineye
so i can see how you added it? lol
Me No Dev
@me-no-dev
MDNS.addService("http","tcp",80);
Shelby Merrick
@forkineye
where did the Arduino service come from then? you have the OTA updater running in sketch too?
Me No Dev
@me-no-dev
ArduinoOTA.setHostname("async-esp");
  ArduinoOTA.begin();
  MDNS.addService("http","tcp",80);
there :D
Shelby Merrick
@forkineye
will give that a shot, thanks!
Martin Ayotte
@martinayotte
I've helped someone on the forum who didn't saw his telnet service, the setHostname() was important.
Me No Dev
@me-no-dev
I still do not see the web server though
Martin Ayotte
@martinayotte
In fact, it was WiFi.hostname(), and personally, I was using wifi_station_set_hostname()
Me No Dev
@me-no-dev
MDNS working fine on my end
Shelby Merrick
@forkineye
your web server finally show up?
Me No Dev
@me-no-dev
yup
it was before
my console tool was dumb
Shelby Merrick
@forkineye
arrgggg.. looks like its this dumb browser now. shows up with avahi-browse -a

does anyone know what the footprint/form factor of the A6 GSM modem is? is it custom, or is it something i can get a breakout for?
or how else can i connect it to a breadboard?

I've bought one. Works fine.
Stavros Korokithakis
@skorokithakis
@gmag11 ah yes, i saw that as well, but i was wondering if there's a board that will JUST give me the breadboard connections (so i can add the resistors etc myself later). i want to design a PCB with the A6 on it, so i want to prototype it
