Android Question Send data from one device to multiple devices with WiFiDirect

Hi all,

I want to send some data (e. g. 4 bytes) from one device (A) simultaneously to multiple devices (B, C, D ...) per WiFiDirect (without router). The data transfer direction is only from device A to B, C, D ...

B, C, D ... should only listen for the data from A. These devices don't need to answer.

Is this possible by WiFiDirect? If yes, is there an example?

Is it possible to create a hotspot and use the same device as server or client?

I tried it myself: Yes it's possible.

1. Device A: I turned on Hotspot "Free Wifi"
2. Device B: I set WLAN to "Free Wifi"
3. Device A: I started my server app. It show me the actual IP = (without Hotspot it was
4. Device B. I started my client app with IP =

Server app and client app show "connected".
