I’d need some clarification on the dependencies between Low-Power, 32kHz crystal, BLE and the ‘required’ connection of LPO_IN to PinE.
When not using/interested in Low Power mode but with a requirement of BLE enabled continuously (mains powered device):
- do we need the 32kHz crystal or not ?
- is the connection of LPO_IN to PinE required (burning a GPIO pin) or not ?
- the design note makes a mentioning of certain operating mode not available in ImpOS 38-, but it’s not clear what is or isn’t available
- can we just pull BT_REG_ON continously high, or do we need to do it via another GPIO (eg for a sequenced enabling of the BLE function) ?
Thx to clarify !
