It's probably possible to do it using socat. Probably something simitar to this: http://www.acmesystems.it/socat

I have done this in the past on other system, I'll try to think on trying it out.

@Cesar-Vargas I did not have to flash the bootloader in my case.

@Cesar-Vargas Looking at the code of /usr/bin/arduino-dock in the arduino-dock-2 package it looks like the flash bootloader command is not supported. The code actually tried to open a file called bootloader as your hex file to upload.

@Cesar-Vargas Glad it helped.

One note, do not update opkg, doing so seems to make it loose the repo.onion.io/omega2 repo. I have to confirm but looks like it.

I'll add this to my review blog of the Omega2: http://net-forces.blogspot.ca/2017/01/omega2-with-arduino-dock2-review.html

Ok, got it to work !

cd /root
opkg remove arduino-dock
opkg remove arduino-dock-2
opkg remove avrdude
wget http://repo.onion.io/omega2/packages/onion/avrdude_6.1-1_mipsel_24kc.ipk
opkg install avrdude_6.1-1_mipsel_24kc.ipk
opkg install arduino-dock-2

Then you can use the sh /usr/bin/arduino-dock flash my_file.hex

Do not use avrdude v6.3-1 as there is a known issue (https://savannah.nongnu.org/bugs/?func=detailitem&item_id=49450)

Re: Omega 2 and Arduino dock.

I have exactly the same behavour. Both via wifi using the Arduino IDE or local from the Omega2:
