## What is UDP/TCP/REST Network Utility?

The only network utility application you will ever need:

1) UDP

Send and/or receive datagrams in both string and hexadecimal format. You can send the datagrams to another instance of the application, a server that is set up to receive datagrams or to the same instance of the application. If you are receiving datagrams, you can specify any valid port to bind to.

2) TCP

TCP Mode supports two (2) submodes: 1) TCP Client and TCP Server. TCP Client allows you to to connect to a TCP Server via specifying the remote host and port the server is operating on. Once connected, messages can be sent to the server; any responses will be displayed in the output view. 2) TCP Server allows you to create an instance of a tcp server operating on a port that is user configurable. Once one or more clients connect, messages can be sent to the set of connected clients. All responses from the client will be displayed in the output view.

Messages and responses can be a utf8 string or raw data in hexadecimal (go to settings to configure format).

3) REST

REST mode supports four (4) request method/verbs: GET, POST, PUT,DELETE. In 'GET' mode, given a url, will display the output in output view. In 'POST' and 'PUT' mode, given a url and a body (e.g. parameters), the output will be displayed in the output view. In all cases, the output can be formatted in RAW or JSON. 

JSON builder feature to easily build the request body is available if POST/PUT is selected.

4) Network Scanner

Scan a single or a range of IP Addresses. Optionally, test if a port is open. Response of scan includes number of packets sent, received, lost, response time and status of port. By going to Settings/Info, you can specify the timeout period for ping and port scans.

• Current private and public IP Address available in Settings/Info tab.
• Network interfaces available in Settings/Info tab.

### 1/5 — Neuerdings NUR NOCH WRBUNG

*2025-12-11, version 2.1*

Ich erinnere mich, dass diese APP mir mal sehr Gefallen hat zur ESP Entwicklung. Leider muss man nach 3 mal tippen nun 2 Minuten Werbung anschauen. Somit werde ich die App nach vielen Jahren nun löschen. Sehr schade!

### 1/5 — Reklam

*2025-09-08, version 2.1*

Sürekli reklam çıkıyor iki kere basamıyoruz. Bağlantı test edicem 30 saniyelik reklam çıkınca değmiyor. Peş peşede iki kere mesaj gönderirseniz tekrar çıkıyor.

### 1/5 — Full page video ads right after connecting to server?

*2024-04-07*

So my connection is idling and will time out while I am forced to watch full screen video ads. NOPE! 
Monthly subscription? NOPE. I e time pay perhaps!
There are better and FREE alternatives to this app. 
Older version was not this bad.

### 1/5 — Rubbish update

*2023-08-02*

Too many annoying ad, unuseable app

### 4/5 — Fast perfekt

*2021-04-18, version 1.0*

Zum Testen von Mikrocontrollern mit Netzwerk ein sehr gutes Tool.
Leider kann man den UDP-Port nicht komplett löschen um einen neuen einzugeben. Es muss immer eine Zahl im Feld stehen. Will man also von 5555 zu 8888 wechsen löscht man alles bis auf eine 5, trägt drei 8er ein, schiebt den Cursor nach vorne, löscht die letzte 5 und fügt die letzte 8 hinzu. Funktioniert, ist aber etwas umständlich🤪

### 4/5 — Pretty useful

*2019-12-20, version 1.0*

I’m using to test my remote server.
One humble suggestion would be that it would be useful to insert ‘\n’ into the TCP messages. Since some of the servers depend on the newline escape char to parse the input.

### 5/5 — Useful

*2019-12-04*

I started to use this app today and So far it’s proven to be very useful. It works for what I needed it for... Hopeful it keeps working. I only have a little issue setting the UDP, if I can get a little help, if not I guess I’ll have to figure it out on my own.
