  • I am confused. I want to know, what is the minimal setup for the chip to broadcast a signal to a phone.

    If I connect VDD_PADS, VBAT to a 3.7V battery, should I use VREGEN, VCHG, VBAT_SENSE? Can I connect VDD_PADS directly to a battery, or do I need a 3.3V regulator?

    The schematic posted in the comments is for a much more complex setup than I want and I don’t think I need to tie all of those pins to power, do I?

No public wish lists :(
