RFFE Tool (DeadBox)

✅ Purpose of an RFFE Scan Tool

The scan tool checks the RFFE bus and reports:

* How many slave devices are present
* Their default addresses
* Whether they respond reliably
* Which devices are functional or missing

This is essential because multiple RF components (PAs, LNAs, antenna tuners, filters, switches) share the same bus.
