What is the Internet of Everything?

Today there are more things connected to the Internet than there are people in the world. In the very near future, pretty much everything you can imagine will wake up. We are leading the next step in the evolution of the Internet and helping change the way we work, live, play and learn.

Compile alljoyn on Yun:

Code:
nano feeds.conf.default

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

Alljoyn is A Common Language for the Internet of Everything  (Machine to machine)

It was initially developed by Qualcomm Innovation Center, Inc. and is now a collaborative open source project of the AllSeen Alliance

Qualcomm Innovation Center, Inc. (QuIC) is a wholly owned subsidiary of Qualcomm Technologies, Inc.

Qualcomm Technologies brings AR9331 (CPU of Yun) to us.

Code:
root@Arduino:/mnt/sda1# wifi --help
Usage: /sbin/wifi [down|detect]
enables (default), disables or detects a wifi configuration.

reset wifi:

Code:
wifi  down; wifi

if you console via ethernet  port:

Code:
ifconfig

Code:
ifconfig wlan0 down

Code:
ifconfig

Code:
ifconfig wlan0  up

Code:
ifconfig

The code you are looking for :

Code:
ifconfig wlan0 down; ifconfig wlan0 up

Plan B:

Set both Yun as Ad-hoc

Try this:

Code:
opkg update
opkg install python-openssl #adds ssl support to python
27  Products / Arduino Yún / Re: yun selected ip interface on: July 22, 2014, 11:08:54 am
Code:
root@Arduino:/mnt/sda1# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.0.1     0.0.0.0         UG    0      0        0 eth1
192.168.0.0     *               255.255.255.0   U     10     0        0 eth1
192.168.240.0   *               255.255.255.0   U     0      0        0 wlan0

if both ethernet and wifi connected to internet , It will go for low-cost routes (metric) . The wifi  net is preferable since it has less metric.

Code:
nano /mnt/sda1/test.sh

or  if you have no MicroSD

Code:
nano /root/test.sh

Code:
chmod 755  /mnt/sda1/test.sh

Code:
Process p;        
  p.begin("/mnt/sda1/test.sh");
  p.run();
  
  while (p.available()>0) {
    char c = p.read();
    Serial.print(c);
  }


always test function of it first at console

Code:
/mnt/sda1/test.sh

FILE_APPEND

need create it first

Code:
touch /mnt/sda1/datalog.txt
at console
