    Bluetooth says connected but tx red light

    I purchased the Bluetooth adapter for my tqi. I installed the app and went into the garage. Clicked on traxxas link module and then push the bind button on the BT adapter and click the button to bind t in the app. It says "connected" but the red light at the top never goes to green on the rx or the tx. The remote and receiver are bound together just fine and the Bluetooth says connected and the BT symbol goes blue. But the rx and tx stay red. So I cannot do anything.

    I have called traxxas support and they said try to reinstall the app. I knew that wouldn't do anything but I figured I could troubleshoot better than I don't know never seen that before. So I then tried to bind it to an iPad mini I had. Same results. I thought maybe it was an iOS issue so I went from my 6s to an old 4s I had laying around and got the same results. So I know he issue has to lie somewhere in the app, transmitter, or the Bluetooth module. Since I have tried to Bing it to an iPhone 6s, iPad mini, and iPhone 4s all with random iOS versions that go fairly far back.

    Please any help on this would be appreciated!!

    First thing I would check is your transmitter batteries. You should always
    use new AA cells with 1.5 volts, Duracell's recommended. Some batteries
    only put out 1.2, I found this important.
