I'm working on connection between ESP8266 and my B4A app. For a proper connection in perent of phone mobile data I should use PreferWifiRouting function that Erel presented here :
Erel: If you are using Android 5+ then you can try this solution

I'm trying to check the internet connection in real time but I haven't figured out how to do it. I've searched the forum, looked at some posts but they were all for b4a. I also tried some of them but they didn't work. Any help is appreciated.

Not exactly a tutorial or Android-only, but a hint to the community for those who like playing with home automation stuff, and possibly for others as well. I happened across this very nice device (IMHO): https://www.tindie.com/products/nicethings/hugo-esp8266-4-button-wifi-remote/ and couldn't...

Looking for advice, I`ve been trying an app using MQTT over wifi. I have a strong wifi signal all the way out at 600+m (clear line of sight), but I`m losing connection to the MQTT Broker at about 150m?
I`m sending about 10KB on data at a time, and the Broker is responding back with about 2KB of...
Hi. I was excited when I found an Arduino board featuring WiFi without external shells. I used the ESP8266 before, and worked, but I (erroneously) supposed that this one would be easier. I have included the libraries needed for using the WiFi (SPI.h and WiFiNINA.h), but the B4R says that cannot...
I searched the forum and found many examples on checking if the device is connected to internet. In my case, I need to check if WiFi is connected but it could be to a hotspot or printer and so there may not be internet connectivity.
What is the proper way to do this?
Hi, I want to display nmea navigation data on an android tablet. The data is transmitted wifi by an AIT3000 AIS and is received by an ipad running InavX. The ipad lives in the cabin of the boat and it's very useful to have a repeater by the wheel, and I want to use an android tablet. Because...
I have a project with ESP8266 as a Access Point with Wifi connection. It has no internet connectivity.
Most mobile phones work good. I have problems with never Sony mobiles (Android 8.1 and 9.0).
They connect to the ESP8226, detect there is no internet connectivity and disconnect. I have found...
Who tried to use an Android device as the server that has been powered up during several months, or maybe year ?
How is the battery state if such usage ?
I think, now embedded control systems can be build basing on an Android device (also as server) + wired Ethernet LAN hosts of...
Hi to all...i need to scan the all wifi around me at the moment and know the ssid.
I test the MLwifi library:
but the wifi_ScanDone not triggered...why?
it necessary or possible to set a time limit to scan?
this is my code...thank you
In B4A, it's possible to use the Simple Wifi library here – https://www.b4x.com/android/forum/threads/simple-wifi-library-updated-v-3-07-09-05-2018.76233/ (which is based on the MLwifi library) to get all kinds of information about the Wifi connection, which I can't find in B4i.
This is a simple library that allows you to control the 15$ Xiaomi´s YeeLight WiFi RGB LED bulbs (real alternative to Phillips Hue) through your LAN.
So far only tested with the RGB version (v1) but maybe it works also with the white bulb and strips.
You need to enable “Lan Control” in the...
I'm working on a B4A project that monitors and shows the current Wi-Fi signal level.
I need to capture WifiManager.RSSI_CHANGED_ACTION.
I took a look at Phone Library, but it doesn't capture that event. PhoneEvents has only the event ConnectivityChanged, which is triggered only on...
I am developing a widget that I want to sell commercially. Doesn't do much really, a few sensors sending information every 250mS or so.
This means comms to IOS and Android phones without a local router connection ( in the wild)
The problem is that depending on the model of the users Android...
