I have a problem with the code below that is supposed to run on an Ardunio Nano with old-Bootloader.
It gives me loads of error messages. The pins are correct. I tested it under the Arudino IDE.
Here is the code and the error messages. The Libs i use ist Rsoftserial in the Lib-Manager...
i used https://www.b4x.com/android/forum/threads/rasynctcp-on-esp32-respasynctcp-on-esp8266.138893/
but when client connected OnConnect sub not raised.
OnDisconnect works fine.
what is the problem?
hello dears and B4X team.
We all know that B4X has improved dramatically over the years...
But the main problem is that the B4X developer community is very small and the number of developers is small, perhaps due to lack of advertising!
The B4X has great potential, but I don't think anyone knows...
I was just trying to make my first project with B4R. Also, I was a newbie in microcontroller programming.
In this my first project, I make a dashboard in Node-RED to display a value from the ESP32 and to control the blue LED on ESP32. The value had been successfully sent, but until now the...
EDIT: Solved = See post #6. Note: Removed the attachement as the reworked B4R library will be shared in the B4R Libraries forum.
This is question is related to the partial wrapping of the ESP32 lib Legoino to B4R lib rLegoinoBoost.
The lib Legoino requires callbacks to access device property...
rLEDController is an open source B4R B4XLib for controlling multiple LEDs.
The LEDController enableds to control up-to 10 LEDs individually, like turn ON/OFF, turn on for period of time or number of timer ticks.
The background for developing this module, is to control a number of...

how can i return IPAddress from in line c.
this is my code.not work

This is a modified version of Erel's BMP180 library with support for ESP8266-01.
The tiny ESP-01 board does support I2C but the SDA and SCL pins are different from the bigger boards' so the standard library does not work. You will not get a reading from the sensor.
Instead, this library...
Sometimes you want to clean the additionnal folder, but are you sure a library is used or not in your projects ?
This app lists all the libraries found in your projets.
Select a folder, check project's type and you got it!
In the left listview are the libraries found.

it seems it is not possible to use a type variable in another type variable.
Type WLAN_Type (IP As String, SSID As String, Password As String, Chanel As Byte, BSSID As String)
Type Settings(Resets As UInt, Summertime As Boolean, WLAN As WLAN_Type)
Hmm, I see that Anywhere Software has created this new section in the forum, so I've decided to add my actual B4X story.
WARNING: This is going to be a loooooooooooong read :cool:
I've always enjoyed creating software from the early days of the humble 48k ZX spekky, to machine coding my 68000...
You can create class modules in B4R but they act as singletons - I can't define a class module say "MQTTBUNDLE" and then create instances of that class. I know the whole thing about low resources and all that but is this something that might be possible in the future? I'm using Types for this...
is it possible to save the selected board like ESP8266 in the project?
So that the "Board Selector" is set automaticly?
When i work with an ESP8266 board an load a new project with an ESP32, the "Board Selector" stays on the last selection and didn´t change with the loaded project...
Hello every Body,
is there someone how likes to write a Library or Wrapper for the M5Stack Board?
GitHub Project with Arduino Library and some cool examples:
There are 3 Boards called "Cores":

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:
Last December I made a request for support for the ESP32 Camera support. Well, I finally found the time to work on it myself and here's my initial attempt at implementing this with B4R. I'm using an ESP32CAM camera board with 4GB of PSRAM (like extended memory for the camera). I'm...
