  • 1. How to quickly determine the point of the problem, whether there is a Calibration mode or a debug mode?
    2. Debugging the antenna, I hope it can be mandatory to transmit all the time. How can I do this?
    3. Bluetooth test, such as EVM, frequency error, power control, where can find the test tools for connecting spectrum analyser devices. and the test scripts?

  • You need to spend time studying the Product Specification to find what test modes are available on the radio.

    Part of your design should have included consideration for how you will debug it, test it, tune it, etc.

    Again, Seriously consider using a module !
