1  Using Arduino / Project Guidance / Re: arduino wifi shield and ip lease on: February 17, 2014, 03:44:38 am
Looking at the wifi shield behaviour I think the IP lease is managed directly by the firmware and that it is not necessary to care about as we need to do in the ethernet library.

may be one solution is to periodically call the wifi.begin but I don't thing this is the best way to solve the lease problem
3  Using Arduino / Project Guidance / arduino wifi shield and ip lease on: December 17, 2013, 04:34:43 am
hello. Looking at the arduino official wifi shield library I can't see anything like an equivalent of the ethernet.mantain() function for reneving the ip addres once the lease has expired. This is not dicrectly handled by the shield, if I change ip from my router and I do not execute once again the wifi.begin() it stays with the old ip number. I do not want to call the wifi.begin() every time I need to send packets on the net because this solution is too much stupid. Do you have any suggestion to solve this problem in a more optimized way?
thanks in advance for any suggestion.

The same is true for me. The sticker on the board has nothing to share with the real MAC address

have you discovered anything interesting about IP lease?
thanks in advance.

If you're outgrowing it, you could use one of the other development environments to build your Arduino projects.

You're right. I will try with visual studio that is my favourite IDE
7  Using Arduino / Project Guidance / IDE: Set many sketchbook path on: December 10, 2013, 05:04:27 am
Hello. Do anyone knows if  it is possible (and how) to  add many sketchbook path editing the preferencies.txt?
I want to do this because I need to keep separate some libraries (I use A LOT of libraries), do you know others way? (now I have only two libraries folders, one is the one created with the ide and one is in the user document folder). I am really disappointed that it is not possible to create subfolder to separate library
 example
library/sensor/libSens1
library/sensor/libSens2
library/actuator/libAct1
library/actuator/libAct2
...

Thanks in advance for your help.

9  Using Arduino / Installation & Troubleshooting / Arduino wifi shield: different board revisions need different firmware/libraries on: December 09, 2013, 10:25:20 am
Hi, I have seen many posts about people having problems with the wifi shield. I want to share my experience with the community.
In the internet you can find many tutorials about upgrading wifi shield firmware. I suggest you to take a look at:
http://mssystems.emscom.net/helpdesk/knowledgebase.php?article=50
http://www.binarytaskforce.com/Weblog/2013/09/21/arduino-wifi-firmware-update/

The point is that not all the board are the same and need the same firmware/library, I have tested two boards. If you have more models and know how to make them work please report wich version of library and firmware must be used with.
You can find the version number on the back of the shield.

*** V023-Rev3.B ***
Upgrade the firmware with the files included in arduino ide 1.0.5 (version 1.1.0) and use the library in the same ide.

*** V023-Rev3.A ***
The right firmware for this version is the one included in the arduino ide 1.0.2. (version 1.0.0) You also have to use the library included in this IDE.
Please notice that if you want to succesfully run the "WiFiWebClient" example you have to comment this line
Code:
client.println("Connection: close");
The same thing is not necessary with Rev3.B.
If you use the new firmware and the new ide using the DHCP you will always obtain 0.0.0.0 as your Ip
If you use the old firmware with the new library you will receive a right IP from DHCP but after you cant communicate with a server.


If you can improve or correct this post you're welcome.

10  Using Arduino / Networking, Protocols, and Devices / Re: Thumbs way down for Arduino WiFi shield. Read before you buy on: December 04, 2013, 11:30:46 am
I totally agree with liudr. in my opinion arduino wifi shield is not ready for the market.
I suggest you to use wifi_dnld.elf version 2.7 with wifiHD.elf version 26 March 2013 with libraries included in ide 1.0.5. This combination is the one that gives me no problems with wifi shiled that uses ATMEL 32UC3A1512-U (wifi v023-Rev3.B). Does anyone know the right combination of firmware/drivers for the model with ATMEL 32UC3A1256-U (wifi v023-Rev3.A)?
Thanks

I suggest to read this post about wifi shield

It is the new original! Do not worry  smiley
12  Using Arduino / Installation & Troubleshooting / Add library folder on: March 04, 2013, 05:39:03 am
Hello. Do anyone knows if it's possible to add a libraries folder (for example editing the preferencies.txt file)?
I want to keep separate libraries that I use in different projecs but I don't know how to do this.
Thanks in advance for you help!
13  Using Arduino / Networking, Protocols, and Devices / wifi shiled Microchip MRF24WB0MA and DHCP on: January 10, 2013, 11:24:06 am
Hi, I have brought a wifi shield based on the Microchip MRF24WB0MA (http://www.electronics-lab.com/blog/?tag=mrf24wb0ma) and I have found this useful library to make it work (http://code.google.com/p/wifi-shield-oe/downloads/list).
Do you know if there is another library that support DHCP like the one included in the IDE (http://arduino.cc/en/Reference/WiFi) that unfortunatly works with another shield?

Thanks in advance for your help

15  Using Arduino / Programming Questions / release 1.0.2 Automatically create libraries folder in the sketchbook on: November 20, 2012, 11:32:20 am
on the release notes v 1.0.2 it is written:
Quote
* Automatically create libraries folder in the sketchbook.

could anyone explain me what this means?
Thanks in advance
