Problem: Arduino WiFi Shield - Find out firmware

Projects Networking, Protocols, and Devices

Hi everybody,

I am trying to do 2 things, read out what firmware I have on my Arduino WiFi Shield. I already did the upgrade to the new firmware, but I want to check if it worked fine. I have an Arduino UNO R3, and I am using the IDE 1.0.5.

I found the following solution online: binarytaskforce.com : 404 Not Found. Here is in the first step explained how to find out the firmware using a FTDI adapter. It should work as follows:

  • Connect the FTDI adapter to a mini-USB cable, which you connect to the PC.
  • Check in your Device Manager which COM-port the FTDI adapter uses.
  • Download/open Putty.exe (Connection Type: Serial; Serial Line: COMx (x=your_COM_port); Speed: 57600
  • Click "Open"
  • Mount the WiFi Shield to your UNO
  • Connect the FTDI adapter to the UNO and to the PC
  • Connect the WiFi Shield via its mini-USB port to the PC
  • Now you should see the WiFi Shield start up on Putty which will show the firmware version
  • If not, press the reset button on the WiFi Shield to reinitialize

Now the problem I am having is that with me it only says the following (even after pressing the reset button):

800×532 9.3 KB

It is not showing the start menu totally. Has anybody else had this before? How to fix this?

You can use the sketch on this link to find the firmware version.

Thanks Tim for your help,

I also found the code below which also gives me a way to check my firmware, but I am still curious why it is not working via the FTDI adapter.

#include <SPI.h>
#include <WiFi.h>

void setup(void) {
 Serial.begin(9600);
 Serial.println("Setup...");
 
 Serial.print("Firmware ");
 Serial.println(WiFi.firmwareVersion());
}

void loop(void) {
  Serial.print("Firmware ");
  Serial.println(WiFi.firmwareVersion());
  
  Serial.println("Scan networks");
  uint8_t numNets = WiFi.scanNetworks();

  for (uint8_t i = 0; i < numNets; i++) {
    Serial.print(WiFi.SSID(i));
    Serial.print("\t");
    Serial.println(WiFi.RSSI(i));
  }
  Serial.println();
  delay(1000);
}
