My device would never work out of the box. I spent a lot of time and energy troubleshooting. After discussion with the company tech support, they determined my Rock Pi was defective.
Since I never got a reply here, I wanted to pass on the solution from the company. I ordered the Rock Pi in early January. It took several weeks to arrive. I’ve submitted for help with a lot of lag in the response. Ultimately, the Rock Pi is defective and has to be shipped back. The company expects me to send it back to Hong Kong. That shipping costs more than the device itself. They won’t replace it until they get the defective product. Then, I have to wait a few more weeks to get it.
BUYER BEWARE… If you have a problem, you’re out the money and time. I should’ve resisted the urge for more power and just bought the Raspberry Pi. Now, I have a piece of electronic junk that does nothing.
