esp8266

Hi All. i wrote an app that connects to my ESP8266 local web server. everythings is ok on Android 4.4.2 . But in Android 7+ i'm facing a boring problem! I have written a function (named NetCheck) whose function is to check the status of the network. If the connected network is not the network...

C'è un modo per collegare un esp8266 al database sqlite in un cellulare? Vorrei inviare dei dati al cellulare tramite hotspot. Grazie

Hello Everybody, I want to save custom type variables in a GlobalStore slot. I can compile and run my code, but when I try to log the saved IP address, the ESP8266 crashes. My code: #Region Project Attributes #AutoFlushLogs: True #CheckArrayBounds: True #StackBufferSize: 300 #End...

Please help. I am trying to read the Analog value from AD0 of the ESP8266. So far not working must be? ADC.Initialize(6,ADC.MODE_INPUT) test=ADC.AnalogRead Tryed ESP.getVcc - gives strange result (native) Tryed system_adc_read() (native)

Anyone know if there is a way to get the RSSI value for a given link between the ESP8266 and some access point to which it is connected without having to do a whole network scan process? For example to be able to regularly check the connection strength to the router in a non onerous way

Hello everybody, i need a little bit help. I know it is not the best idea to connect a ESP/Arduino to a SQL Database but i need this to reduce the complexity of my project. There are better and faster Solutions like this...

Hi, Im looking for some advice, i have an idea for a project where i will need to connect a number (let say 10, for now) ESP8266 modules to a B4A app running on an Android device? Ive been browsing the forum, n seeing alot of options...so looking for opinions on best method. Data sent will be...

Hello, i Have modified the rAdafruit Neopixel Library and added some new features (@Erel hope this is ok for you?) This Library is Based on https://github.com/adafruit/Adafruit_NeoPixel V. 1.3.1 I Have test this Library with the ESP 8266 and i Hope it will work on other Platforms too! See the...

Hello Erel, could you import the ESP8266 ESP-07 Board to the "Board Selector"? At this time there are ESP-12 an ESP-13 Boards an many other but no ESP-07. ESP8266 ESP-07: I have problems by setting up the "Generic ESP8266 Board" to use this with my ESP-07 board. THX

There are a lot of post about it: https://www.b4x.com/android/forum/threads/esp8266-wifi-and-socket.69164/#post-438940 https://www.b4x.com/android/forum/threads/not-possible-to-remove-wemos-mini-accesspoint.72501/...

The B4R rMQTT library is based on the well known Arduino PubSubClient library written by Nick O'Leary. It's a subset of this library - with the most important/used methods wrapped. I do have a scenario that requires some of the additional methods to be wrapped as well. Specifically: boolean...

Having been away from micro-controllers for much of the year (my have things changed!), I will admit that I was puzzled by references to FreeRTOS and ESP32. I never payed much attention to it as when you compile a sketch in Arduino or a B4R program - *it just works*. I originally got started...

For the ESP8266 watchdog, can be very simple to use. #Region Project Attributes #AutoFlushLogs: True #CheckArrayBounds: True #StackBufferSize: 300 #End Region Sub Process_Globals 'These global variables will be declared once when the application starts. 'Public variables can...

This is based on EREL Project ESP Configurator... https://www.b4x.com/android/forum/threads/esp-configurator-based-on-b4rserializator.81452/ Just I port the whole code into An App...You can download the Apk file from here or Download from PlayStore. It does not contain ad.Freely available...

Hi All, i have problem to convert this native arduino codes as shown below. my board based on wemos D1 R1 Thanks void loop() { if (Serial.available() > 0) { String incoming = Serial.readString(); if (incoming.indexOf("{")>=0 && incoming.indexOf("}")>=0) { Serial.flush()...

The Arduino IDE can find the IP address of the ESP8266 (mDNS:arduino) when it is programmed with OTA, but we also have ESP-LINK software, which allows the ESP8266 to work in transparent (TCP / IP-Serial) mode allowing reprogramming of microcontrollers like Atmega328 (Arduino UNO / Nano / Pro...

I have running a timer every second for making a stopwatch. Three variables sec, minute and hour are taken. Sec is incremented with every timer tick and minute is incremented when sec value reaches 60. Everything is working fine. Now I want to broadcast the value of time in 00:00:00...

I can connect to my ESP8266 just fine. But quite often after just a few seconds (2,3,4,5 seconds), it randomly disconnects. Sometimes it takes a bit longer to disconnect randomly, after a minute or so. And it does so on LG Nexus 5X. On the other phone the app is working just fine and can...

A client asked us to research environment monitoring options for their server room. The servers themselves have that built-in but they needed something for the room in general. The following is a proof-of-concept (POC) that I came up with using several of the B4X tools to fulfill their...

Hi, I have an esp 8266 (Wemos mini) and I'm connect on wifi with wifi.connect2(ssid,pass). Sometimes, the board can't connect to the wifi and my sub stop and wait the response. But on my DHCP Server, I see the board and the server send a ip address. 2 questions : - Why the board wait even the...
