Limited charger conection

Dear all,

I understand the the base concept of QI is that all RX and TX should be compatible.

Unfortuntatle I wanna build a wireless charger without QI certification but based on the TI solution.

In certain industries it is necessary that the system only works with a predefined charger system.

E.g. in medical where certain safety regulatories apply.

Would it be possible to somehow tweak the BQtesla system to somehow accept only certain chargers?

Or would I have to implement another initiating system like having a hall sensor and a magnet on certain position to switch on the RX device.

Thanks

Christian
