The issue with the springs was with a particular batch of Yuns, I don't think it persists anymore
....

Are you working for OEM of Yun? Can you show us more light?

1. Enable DHCP serverand static IP at WAN ( ethernet ) .





2. Scan WIFI network



3. Join WIFI network



4. setup firewall, masquerading=1, forwad as accept

Hi ,
                 Thank you Sonnyyu For your quick response.
                  As i have read we should be careful enough while handling with the multiple shields as we have to take care of pin numbers.
1) Is it possible to use multiple shields simultenously working  on "Arduino Yun"  where two or more  shields sharing the same pins.

2) If possible how can it be achieved.   

                   Thanks in advance.

Regards,
Shashi.

If I were you, I will repost question at separate topic and make it  address to public.

Make sure use barrier_breaker even Yun is not barrier_breaker.

sonnyyu have you tried it? does it compile/work? It seems like an easy addition to the available packages

Yes, I tried and only got it work at barrier_breaker feed.

Plan B:

gprs shield = 2.5G  technology.

Use 4G Hotspot  to connect with Yun wifi you will get much faster speed and some time even free at monthly charge.

$0/mo - 4G Hotspot - FreedomPop.com‎
Just a one-time $29.99 activation. Get 500MB of free internet monthly.

2) Can we port contiki OS on  Arduino Yun board ?

better support here:

3) Is it possible to incorprate alljoyn frame work on Arduino Yun board ? If yes how can it be done ?


Compile alljoyn on Yun:

Code:
nano feeds.conf.default

src-git alljoyn https://git.allseenalliance.org/gerrit/core/openwrt_feed;barrier_breaker

 Make sure use barrier_breaker even Yun is not barrier_breaker.

1) As part of developing ipv6 based IoT network, I am trying to include light weight protocols like CoAP, LoWpan, RPL on Arduino Yun board. But unfortunately all these protocols are supported for ipv6.
Just curious to know does Arduino Yun board supports ipv6. If yes, how can I enable ipv6 on it or is it enabled by default ?
And is it possible to incorporate all IOT protocols (CoAP, LoWpan, RPL) on Arduino Yun Board ?
Please clarify.
...

Code:
opkg update
opkg install kmod-ipv6 ip6tables radvd ip 6to4

from "HttpClient.cpp"

Code:
unsigned int HttpClient::get(String &url) {
begin("curl"); 
addParameter(url); 
return run();
}

Rewrite HttpClient by use directly Process.

Code:
curl -h
...
--connect-timeout SECONDS  Maximum time allowed for connection
...
-m, --max-time SECONDS  Maximum time allowed for the transfer

If your application is very CPU intensive, then you could select Broadcom BCM4709A0 (1 GHz, 2 cores, WiSoC).
It will run much faster than BeagleBone Black/Arduino TRE/Raspberry Pi.

14  Products / Arduino Yún / Re: price range to produce a board yun based on: August 28, 2014, 10:42:18 am
AR9331 is still the lowest power.  Yes, I agree.
and the cheapest WiSoC.  Unsure.

Ralink and MediaTek

RT3050
RT3070
RT5350
MT7620


by use MT7620 you could save up to 40%.

FYI;-

The heart of Yún is CPU - AR9331, here is the market position of it.

AR9331 (MIPS 24k@400MHz, 1x1:1, 150Mbs/2.4GHz, PHY/100Mbs)

AR9341 (MIPS 74Kc@500Mhz, 2x2:2, 300Mbs/2.4GHz, PHY/100Mbs)

AR9344 (MIPS 74Kc@600MHz, 2x2:2, 300Mbs/2.4GHz, 450Mbs/5GHz, PHY/1Gbs)

QCA9558 (MIPS 74Kc@720MHz, 3x3, 450Mbs/2.4GHz, 1300Mbs/5GHz, PHY/1Gbs)

It is already on bottom of the food chain.
