Remotely upload sketch to Arduino Yun using command line.

1. Compile and get the hex file
   
   In Arduino IDE,
    -  Sketch > Export Compiled Binary
       Wait for the compilation process to finish
    -  Sketch > Show Sketch Folder
       Let's take the one without bootloader.
    
2. Copy [your_sketch].hex to the Yun You@PC $ scp [your_sketch].hex root@arduino.local:/tmp
3. SSH into Yun You@PC $ ssh root@arduino.local
4. Merge your sketch with the bootloader (for the one without bootloader) root@Arduino:~# merge-sketch-with-bootloader.lua /tmp/[your_sketch].hex
5. Program the MCU (ATMega32u4) root@Arduino:~# run-avrdude /tmp/[your_sketch].hex Done!

[Failed] Installing OpenBTS for USRP1 on Ubuntu 16.04

# Firstly, install GNU Radio 3.4.2 for USRP1
# http://blog.puiup.net/2017/05/installing-gnu-radio-342-for-usrp1-on.html

git clone https://github.com/RangeNetworks/dev.git

cd dev

./clone.sh

export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig

./build.sh USRP1

sudo dpkg -i BUILDS/--YOUR_TIMESTAMP--/*.deb

sudo apt-get -f install

## -- 8th May 2017
## PROBLEM#1: Cannot start OpenBTS daemon
## CAUSE: Compatibility issue: OpenBTS is using "upstart" but Ubuntu uses "systemd"
## SOLUTIONS:
##     - Wait for the OpenBTS to fix this
##     - Convert upstart scripts to systemd scripts by yourself
##     - Change your ubuntu to use upstart
##     - Back to Ubuntu 14.04
##     - Run it manually. <--- This works

## -- Some time after
## PROBLEM#2: OpenBTS process keeps terminating after a few seconds.
## CAUSE: The driver problem?
## SOLUTIONS:
##    - Take time finding and hacking into the obsoleted codes/device?
##    - Throw away the USRP1 and find new equipment.
