Hi,

slightly will have to repeat myself:

This is wireless communications. Not only do you have to configure all
devices in a compatible manner, channel and receiver conditions can make
interoperation problematic.

You will have to apply your own signal processing / wireless education
to debug this.

I don't understand this question, sorry.

Same answer as to 1. You're not doing any signal-level debugging on
this, so we can't help you.

Same answer as to 1.
