If low current consumption is required but have no access to the External 32kHz Crystal, then this clock source is recommended. However, selecting this clock source will have the sleep clock accuracy larger than 500 PPM, which is supported if the peer device is also an ESP chip. If the peer device is not an ESP chip, here's some Bluetooth LE event not supported:
