It doesn't work. 10cm wires, 2 parallel 4k7 resistors

@matasondrak 2k2 might be to low... I thought about 3k5 or so. I have a small decade resistor box for experiments.

hi guys , I'm trying use 3x3 keypad with 6 ESP8266 pins and Arduino Keypad Library , according to its library, row pins set input pullup and column Pins set output and LOW and in pool all output pins versus input pins will be checked , but after running the following sketch, notice only couple of key combination works (2&16 ->e 0&16->h) any clue really appreciated
#include <Keypad.h>

const byte ROWS = 3; //four rows
const byte COLS = 3; //four columns
//define the cymbols on the buttons of the keypads
char myKeys[ROWS][COLS] = {
 //16   12  4
  {'a','b','c' }, //5
  {'d','e','f' }, //2
  {'g','h','i' } //0
};
byte row_Input_pullup_Pins[ROWS] = {5, 2, 0}; //connect to the row pinouts of the keypad
byte output_low_state_colPins[COLS] = {16, 12, 4}; //connect to the column pinouts of the keypad

//initialize an instance of class NewKeypad
Keypad customKeypad = Keypad( makeKeymap(myKeys), row_Input_pullup_Pins, output_low_state_colPins, ROWS, COLS); 

void setup(){
  Serial.begin(115200);
  Serial.println("\n\n\nStarting.........");
}

void loop(){
  char customKey = customKeypad.getKey();

  if (customKey){
    Serial.println(customKey);
  }
}

@mkeyno , do you have external PullUps, even on GPIO5 ? does the 'B' key also working ?

Any reason why SPIFFS.open(NAME, "r") should fail for an existing file? Should I retry if there is a fail or can I consider the file does not exists?

It is possible to put my esp (which is client and connects on a local server IP (192.168.1.200) to connect in a ddns over the internet?
Currently the program is made server "192.168.1.200" it already connects
Develo
@devyte
Look at the easyddns examples
rodrigocirilo
@rodrigocirilo
Thank you, but ... I need the opposite.
in this example easyddns the esp will be found through the right ddns address!
I need esp to find the server that is running a ddns address.

@devyte
Isn't that just a normal dns lookup? Hostbyname or something, if mem serves
Clemens Kirchgatterer
@everslick
dynamic dns is just DNS from the hostname lookup POV. but don't confuse wit mDNS, which is a different thing.
rodrigocirilo
@rodrigocirilo
see my esp is a client that connects to a c # application that is the server, the site that is the server is a fixed IP so my search for this IP. has worked. it happens that the ip will not be fixed anymore it will be dynamic and for my esp the server will have to search for a ddns and what I want to know with the noble colleagues is which the command to use. currently it looks like this: Client.connect(server, Port)) the server is a IP,
I want to change this ip to my ddns example
Testddns.dyndns.com
would be Client.connect(testddns.dyndns.com, port)

I'm seeing connections to an AP take about 300-500ms (with static ip) is there any way to make that faster?
I'm passing the channel an AP bssid, but that doesn't seem to make any difference at all
riataman
@riataman
hopefully there would be a way to avoid the rescan when connecting

Hi Guys, I wanted to write unit and integration testing for my software on esp8266. I couldn't find a lot of good frameworks for ESP8266 unit or any other type of test automation. Wanted to get an idea of standard ways of testing.
Akash Ashok
@thehellmaker
@enriquecml Thanks a lot enrique. Will take a look. I am looking to run tests on ESP8266 directly. So I am not looking to mock on the computer where the code compiles but more like I upload the code and run the tests there on the device. And on the device any dependencies I would like to be mocked
Mehrdad K
@mkeyno
thanks @martinayotte , yes I did , also I test with external pull down as well , but still most of keys not working
In other try I use interrupt to capture pin status but same result , would you please check it in this issue esp8266/Arduino#3723

Hello
Is there a manual somewhere to add a new reset method for esptool.exe?
And do it so that it was to select resetmethod in arduino IDE.

I have a question about the bootup message 'boot mode: (x, y)', where I can find information about 'y' ?. I remember it was somewhere but now I can not find it anywhere.

Hi all!
I'm trying to install the RC1 staging version of esp8266/Arduino in PlatformIO. Could anyone please point me in the right direction?

Has anyone had the problem with WiFi.softap() where it partially connects? It is firing the WiFi.onSoftAPModeStationConnected() event, but doesn't seem to give my laptop a local ip address.
Develo
@devyte
@zenmanenergy which wifi mode? Which core version?
Steve Nelson
@zenmanenergy
2.4 rc2 WiFi.mode(WIFI_AP_STA);
Develo
@devyte
In that case the sta side will be attempting to connect to some your router on the router's channel. Meanwhile, the ap side may be serving on a different channel. While the sta is trying to connect, the ap gets dragged along, because there is only a single radio shared between the two. Your client connected to the ap will see the ap drop out because of the channel swapping. In that case, if the ap dhcp server is sending the reply during the channel swapping, the client may never receive itm
Figure out the router's channel, set the ap to the same channel, check if the dhcp works then
Also, implement a timeout for the sta's attempts to connect
I.e.: after 10 failed attempts, disconnect and stop trying
Steve Nelson
@zenmanenergy
@devyte do you think just switching it to either ap mode or sta mode by itself will resolve it?
I guess i don't really need it to be both. I was just doing that to enter the settings.

@mikekgr
hello there!
Is there any good how to, in order to get direct port bit access/manipulation in the ESP8266, in the sense that Atmega does?
Develo
@devyte
@zenmanenergy I suggest testing ap-only, and see if the dhcp works correctly. The wifimanager does one or the other: it tries sta, if that fails it stops trying and brings up the ap. Me, I'm doing stationap mode with the ap on the same channel as the router that the sta tries to connect to.

Hi guys.
I looking for AES encryption library for Arduino ESP8266 and came across plenty
it appears it's not included already in the SDK so I'd need to use one of them
Does anyone knows if there's an AES library that supports CTR mode for Arduino ESP8266?
I don't want to be working with Initialization Vector and CTR mode would be the case
Rinaldi Segecin
@rsegecin
well at least when I'm to cipher in nodejs with "crypto" library I don't need to specify an IV when I use "aes-256-ctr"
Matej Sychra
@suculent
What's wrong with IV? It's just a number.
