  • Slow ping rates with SDK Version 4.3

    I have an old pair of ZTE Android phones that we've been reliably using for the last several years. I recently downloaded the new V4.3 SDK. I have noted a considerable slow down in the reported ping rate seen on the Driver Station App. On older versions of the SDK I could reliably get ping rates of 2-4ms. With V4.3 I am now getting ping rates varying between 15-27ms, about 5-10 times slower. I am testing the Android phones in a very quiet WiFi environment so I doubt there is any outside interference. I'd be interested in knowing if others have experienced the same issue and if this might be a problem during tournament play.

    Just FYI, gamepad data is only sent from the DS to the RC every 40ms, so a 27ms ping (13.5ms single way) still gets you updated gamepad data 3x faster than before you'll start to notice any "lag" when driving the robot.

      I can confirm this same change with 4.3 on ZTE phones
