Hi @Kenneth-Lim, it seems that your Omega was configured to connect to your home router, but wasn't able to connect properly. In order to turn on the Access Point, your primary network needs to be either turned off or properly connected. Since it wasn't connected properly, access point wasn't able to start. We do have a service running in the back ground called wifi-saint that checks to see if primary network is setup properly, and turn it off in order to allow access point to run, however, it is run at an interval of every 5 minutes.
Hi @john-b, Yes, there is a way for you to "make" your own ethernet expansion, however it is going to require some hacking, especially since you do not have expansion dock. The Arduino Dock does not break out any pins from the Omega itself, so as fas as flashing the Omega goes, it won't be able to contribute much.
Jumpers J1/J2 set the divisor used for the output signal frequency
Jumper ENABLE is an enable jumper - would normally expect this to be permanently installed
Jumpers I2C_PU select whether or not pull ups are used on the I2C pins
Jumpers I2C_ADDR set the I2C address allowing up to two such timer oscillators to be used with different addresses
The following zip file contains my own Arduino library sources related to this (I think I have included all relevant files) : ArduinoOwnLibs.zip - let me know if you need info on how to use these.
Just for further information, I too use a Spakfun Shield adapter for the Teensy (https://www.sparkfun.com/products/13288 _ assume this is the one you refer too) though I have made some modifications to it to expose the second I2C interface that the Teensy has which isn't otherwise exposed on the Sparkfun shield.
My original proposal for an alternative Arduino Dock in this topic was intended to reflect something like this Sparkfun Teensy Adapter but for the Omega
Write your code on your native platform once complete or ready for test merely launch MobaXterm hook up a session of your choice ftp or sftp then drag and drop to your Omega directory. Simple and fast.
