In this example the Arduino board acts as a server. Clients can list the available files and can download files stored on the SD card, which is part of the Ethernet shield. https://www.b4x.com/basic4android/images/SS-2016-06-08_11.24.37.png To make the solution more reliable, the communication is stateless, similar to HTTP requests. The client sends a request, the server (Arduino) sends... such as the Arduino Mega. During the tests I've found a bug in SD.ListFiles which can cause some of the files to...

. This is a nice example as it shows how B4X tools can be used to program both the Arduino side and the Raspberry Pi side. Arduino and Raspberry Pi complete each other nicely. The Arduino is easier to connect to... with a USB cable using the Arduino built-in usb to serial converter. During development it is convenient to run the RPi side on the PC. Otherwise you need to disconnect the Arduino each time...

https://www.b4x.com/basic4android/images/SS-2016-05-11_13.27.00.jpg The GSM shield allows the Arduino to connect to cellular networks. This opens the door for many interesting outdoor solutions. There are all kinds of shields available. Make sure that the shield you are using is configured to work with pins other than 0 and 1 (which are used for programming the Arduino). We will use SoftwareSerial with AsyncStreams to communicate with the GSM module. The GSM shield is controlled...

HI, All Strange, my ESP8266 project works OK in B4R, but now i'm trying to start with ESP32 ... with no success. Arduino IDE connects, starts the board OK, logging is OK, the reset button makes the reset OK. In B4R the flashing of the min template app is OK, but no log output. 108658 Sub Process_Globals Public Serial1 As Serial Private wifi As ESP8266WiFi End Sub Private Sub...") End If End Sub p.s. Arduino can log the output of B4R sketch ! ets Jun 8 2016 00:22:57...

After installing B4R, it is required to set the path to arduino.exe. In the dialog window, a filter is set so only this file can be selected. Unfortunately, in the version 2.0.3, the arduino file is called Arduino IDE.exe, which means it cannot be selected. Two possibilites: Rename the arduino file (not my preferred selection) or remove the filter in B4R. I hope Erel will remove the filter. ?...

https://www.b4x.com/basic4android/images/SS-2016-04-13_15.50.49.png With the rSoftwareSerial library you can turn regular pins to serial ports. This is useful as the hardware serial is used by the IDE during development. There are some limitations to the supported pins: https://www.arduino.cc/en/Reference/softwareSerial As an example, the following program should run on two boards. When you press on the connected button, the on-board led on the other board will turn on. Sub Process_Globals...

Hello everyone, This has been a long time coming, but B4R now has an ArduinoBLE library supporting.... I originally wrapped a basic version of this ArduinoBLE library a couple of years ago, with only limited... useful functions as possible for the B4X community. About this library: rArduinoBLE is a modern, high‑performance Bluetooth Low Energy wrapper for B4R, built on top of the official ArduinoBLE framework. It brings BLE Peripheral and Central capabilities to ESP32, Arduino Nano 33 BLE, plus much more...

The new esp32 SDK is got of very huge size and the downloading (and + unpacking + installation) is failed due to the timeout is out.
