Notes:
AT+CFUN=1 used to set radio function and power mode.
Instant Peak Tx: The peak current during a transmission burst period or connection. This current is handled by
bulk capacitance in a design.
Measured Current: The continuous current during a Transmit with the radio transmitter at specified power.
Inrush Charge: The total inrush charge current amplitude at power on.
