When I remove the 2.4 Ohm resistor, the P-FET works just fine. However, when I try to drive the load, it can only partially turn off. The whole thing has been really weird.
Are you phantom powering the BLE device through the data pins? Perhaps a R10K from drain to ground would help
I wondered why you had a R in series with the supply. Thought you were trying to use it as a inrush current limiter of sorts.
