Hello there

I have started playing around with an Raspberry Pi. Can you guys maybe help me?


I have connected a WiFi dongle (https://thepihut.com/products/wifi-dong ... bi-antenna) to my Raspberry Pi.

The Pi sends a signal through UDP out. Now, the question is how can I "measure" or "visualize" the signal that is sent out via the dongle? And, how far can a Pi send such a signal?

Thanks for the help!! Much appreciated.

Use commands like "iwconfig" to see the quality of the network link (=how good the cable is) between a wifi client and its access point.

If link quality is poor (40% and below), data communication will suffer. Some protocols/applications are made to run over unreliable links, but in general things can get very complicated, very fast. Absence of evidence [data] is not evidence of absence [no data]...

UDP and the smartest protocol will never fix a broken link, get the best link quality you can, first.

Thanks mate!
