The above is a small series to introduce the Android Socket thread connection OpenWrt and Arduino SCM serial port Two-way communication, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
