You need to use UDP broadcasting. Start with this example: https://www.b4x.-chat-with-auto-discovery.75713/#content

This is not something that you can simply find. Your device isn't familiar with other devices on the network. You can use UDP broadcasting feature to find other devices running your apps: MQTT Chat with Auto Discovery

There is no relation between MQTT and UDP discovery. It is just an example that uses UDP to discover the "mqtt server". This is not what I said... Finding the broadcast address: B4A: https://www.b4x./#content B4J / B4i: UDPSocket.GetBroadcastAddress You should use UDPSocket.GetBroadcastAddress

Debugger improvements: Better handling of multiple installed debug apps. Bug fixes and better logging. Deployment process improved. Auto installation is now the default. SetDebugAutoFlushLogs keyword. When enabled a short pause is added in debug mode when internal logs are printed. This is useful f

Hi, just tried UDP discovery over hotspot but unfortunately it doesn't work. The good way for you is MQTT. If you are using ESP32, think about bluetooth LE for discovery, get the IP from bluetooth then connect via WiFi Bye

link: Yes, the ESP has a short routine to answer to the app. It sends a json containing its IP and some other info about it (i.e. the device name, so it's e
link: @ DavideV, mmm, i would be very interested in how you did that... Did you also change something in the ESP program (to broadcast that UDP?)?

This is an extension to the MQTT chat room example: https://www.b4x.com/android/forum/threads/b4x-mqtt-chat-room.61568/#content It is a chat room where one of the devices acts as a server and the others as clients. https://www.b4x.com/basic4android/images/SS-2017-01-30_10.56.47.jpg The difference

UDP <> reliable If you want to make UDP reliable, be prepared to write some code, which will nullify your lightweight goal. Have you seen this? https://www.b4x.-chat-with-auto-discovery.75713/#content
