Hi, I am testing with the example script WiFiS3 -\> WiFiPing It connects to my WiFi ok and prints the connection details to the serial monitor. It then tries to ping some remote addresses but each fails with a timeout: SSID: IP Address: 10.0.0.220 signal strength (RSSI):-74 dBm Trying to ping [github.com](http://github.com) on IP: 140.82.121.4 Timeout on IP! Make sure your WiFi firmware version is at least 0.5.0 Trying to ping host: [www.google.com](http://www.google.com) I have been through a few iterations with issues like making sure I was connecting to a 2.4Ghz network (thanks ChatGPT for resolving that one). Then trying to update the firmware from inside the IDE which fails every time - eventually managed to get it done manually despite a lot of bad info around on this. Now on latest firmware 0.4.1, but it still doesn't work. I will try other protocols like HTTP next, but I would really prefer to get ping working as this is meant to replace an existing server monitor app running on a windows server which has been working fine for years using pings but I want to retire it. ---

My R4 WiFi was still on 0.4.1 so I took the opportunity to try out the ping example. As I expected, it failed with a timeout. Once I upgraded my firmware to 0.5.0 the example worked fine and was able to ping [github.com](http://github.com) and [www.google.com](http://www.google.com). ---

In this case it was that it had not been implemented yet.

As @ptillisch has already pointed out, ping support was added in the 0.5.0 firmware. Which is why I could take the opportunity to try the example out with my board with 0.4.1 firmware, see that it failed as expected (because the firmware didn't support it yet), then upgrade to 0.5.0 (where it was supported) and see that it worked. Nothing to see here, folks. ---

@ptillisch , Thanks very much for testing that, and pointing out there is a later firmware. I had thought I had got the latest when I updated it earlier today. I'll look again... ---

@van_der_decken - sorry I tagged the wrong person before. I found the later firmware. In case anyone else needs this, you need the pre-release builds, as the IDE only lists the released builds of which the latest currently is 0.4.1. I downloaded 0.5.1 and manually flashed it. All works great now, thanks for your help.

> [@talisman334](#): > > IP Address: 10.0.0.220 Hmm... Looks odd for a local IP address from your router. What IP addresses do other WiFi clients like phones & laptops have on your network? ---

@PaulRB , It's fine - I have always used that 10.0.0.0/8. Apart from less typing it's a historical thing because my first office server was MS Small Business Server which was based on Windows NT 3.51. Incidentally I still use that server running in a VM and upgraded to Windows NT4 lol. Not connected to the net of course. I have other routers for phones etc using other local address ranges like 192.168. ---

Hi, where and how do you get 0.5.1 since the IDE only shows 0.4.1? I can't find it on GitHub. I need to use ping on my new Rev 4, like I do on my Rev 2 boards! Thanks! ---

I am getting stuck at the compile step. Using Git Bash, this is the error: /arduino/update-firmware (main) $ ./compile.sh Error during build: Platform 'esp32-patched:esp32' not found: platform not installed Platform esp32-patched:esp32 is not found in any known index Maybe you need to add a 3rd party URL? ---

Damifino. I do the update manually because there isn't an rPi auto updater. 1. Install esptool.py if not already done (`pip3 install esptool`). 2. Download latest firmware from [Releases · arduino/uno-r4-wifi-usb-bridge · GitHub](https://github.com/arduino/uno-r4-wifi-usb-bridge/releases) 3. Extract the bin file from the firmware subdirectory in the zip. 4. Short bottom left and bottom centre pins on 3x2 header near USB connector before powering on. 5. Remove jumper after applying power. 6. Erase flash with: `esptool.py --chip esp32s3 --port erase_flash` 7. Write flash with: `esptool.py --chip esp32s3 --port write_flash -z 0 ` ---

Because I'm a total novice and doing something wrong, lol. At least you taught me how to get the .bin file. So I am really close now....
