STUSB4500QTR as voltage regulator?
Can I use STUSB4500QTR pin 23 (VREG_2V7) as power source for low power MCU? Max current consumption would be 0.5mA, avg current consumption would be a few uA.

BlueNRG-2 - how to switch on the LS RO oscillator with working LS XO oscillator without external reset (RESETn pin) or power cycling after firmware updating over "OTA"? The chip is BlueNRG-232 (it reports a "chip version" 1.0.0).
We use BlueNRG-2 in custom sensor. The original firmware uses LS XO (32 kHz crystal). But we need to have ability to choose the LS "RO" or "XO" after firmware updating over "OTA" (FOTA). It seems that if LS XO has been turned on once then the LS RO i...
