@Suman-kumar-Jha One more time This was the originally installed '/sbin/yunbridge' file on Omega2(+) : root@Omega-5BE1:/# cat /sbin/yunbridge #!/bin/sh stty -F /dev/ttyS0 2500000 clocal cread cs8 -cstopb -parenb exec < /dev/ttyS0 exec > /dev/ttyS0 exec 2> /dev/ttyS0 askfirst bin/ash --login I've modified it because we can't set either 250000 (ie. 250,000 250 kBaud) or 2500000 (ie 2,500,000 2.5 MBaud) with the stty command and ttyS0 (UART0) is occupied by the Serial Console on Omega2(+) - so I tried to use ttyS1 (UART1) instead This is the modified '/sbin/yunbridge' file: root@Omega-5BE1:/# cat /sbin/yunbridge #!/bin/sh stty -F /dev/ttyS1 115200 clocal cread cs8 -cstopb -parenb exec < /dev/ttyS1 exec > /dev/ttyS1 exec 2> /dev/ttyS1 askfirst bin/ash --login That's it! I think 115200 Baud is a good choice. It's good for all - for Omega2, Arduino, Arduino Bridge, Arduino IDE, ... IMO the serial line speed is not the most important problem in this five-liner script now. BTW please try it what you want: root@Omega-5BE1:~# stty -F /dev/ttyS1 250000 stty: invalid argument ‘250000’ Try 'stty --help' for more information. root@Omega-5BE1:~# stty -F /dev/ttyS1 2500000 stty: /dev/ttyS1: unable to perform all requested operations root@Omega-5BE1:~# stty -F /dev/ttyS1 115200 root@Omega-5BE1:~# stty -F /dev/ttyS1 speed 115200 baud; line = 0; -brkint -imaxbel

The Omeage2 has no analog, limited PWM, non-deterministic timing. Arduinos have a varied number of analog, digital and PWM pins, are deterministic as to how long things take to run, have 'bank' i/o support (which I've not seen implemented on any copy device), software serial, sleep mode, ... So, no.

@Ashu-Joshi Arduino Dock Initial Setup tutorial is related to Omega (ie the previous version) and the first version of the Arduino Dock. Use it carefully! @Ashu-Joshi said in Arduino Dock 2: Setup: I wired up the Expansion board with Omega2+ and the Arduino Dock 2 expansion - BUT I could NOT get the Omega2+ to power up at all. Omega2 is a 3.3V povered device and its GPIO pins are not 5V tolerant. VIH (Voltage Input High) absolute maximum is 3.3V - 10% + 0.3V = 3.27V ... 3.3V + 10% + 0.3V = 3.93V. Arduino is 5V powered on the Arduino Dock 2 so it may damage your Omega2 if you connect them in the mentioned way.
