I am trying the attached sketch udp client-server (client-test.ino) as a udp-server with the udpclient.c as a client
Hardware "Arduino Uno WiFI"
From the part of the client ....
root@jb-home:~# ./udpclient 192.168.1.140 49150 Type a sentence to send to server: Hello there You typed: Hello there
From the part of the server ....
Attempting to connect to SSID: Lithinon Connected to wifi FirmWare Version: 1.0.0 SSID: Lithinon IP Address: 192.168.1.140 signal strength (RSSI):-68 dBm Starting connection to server...
I get no reply.....any hint?

I get no reply.....any hint?
Print a message AFTER the call to Udp.begin(). If that never returns, loop() will never begin.

the WiFi Link versions 1.0.x are full of bugs.
I did it already, but the problem is the same.

I made bug-fixes to WiFi Link firmware and library in my forks . Use it with my Uno WiFi Serial1 library.

You changed your code, but did not post the revisions.
You should get more serial output. You did not post that new output.
The problem is the same - you are it.

I try firmware download following GitHub - JAndrassy/UnoWiFiDevEdSerial1: Implements Serial1 of Arduino Uno WiFi Developer Edition board to access the on-board ESP8266
but fail
in the attached screenshot you can find details
did you let the Serial Monitor open? and remove the Hello println it disturbs the esptool.
and why do you install the AT firmware?
I see, the link to GitHub jumps up on the page. Follow "UNO WiFi with WiFi Link firmware " chapter.
Hi Juraj,
I select Arduino Uno WiFi board but the compilation gives

you should select Arduino board from esp8266 core for Arduino IDE. did you install it?
Yes but now

install ArduinoJson library in Library Manager
a new error in PATH
.......
exec: "make": executable file not found in %PATH%

The problem is caused by selecting Tools > lwIP Variant > v1.4 Compile from source when you don't have the path to make in your PATH environment variable (likely not installed at all since you're on Windows). The problem will be solved if you select Tools > lwIP Variant > v1.4 Higher Bandwidth .
I installed WiFi Link Library from GitHub - JAndrassy/arduino-library-wifilink: Arduino Library WiFi Link and i try
WiFi UDP Send and Receive String example but i get the following errors.
Any Hint ?

now select the avr board Arduino Uno WiFi.
and first try the WiFiLinkWebClient example of Uno WiFi Serial1 library
Hi juraj,
I am trying from the beginning with new installation of arduino IDE.
In the step "Arduino ESP8266 filesystem uploader"
I take that, us you can see in the attached file.....
What am I doing wrong?

You forgot to follow the directions:
Juraj:
Select Tools > Board > Arduino Uno WiFi .
