In most designs, the additional sleep current is a reasonable trade-off for significantly improved RTC Timer frequency stability and reduced time drift during sleep.
**Bluetooth LE** requires sleep clock accuracy within 500 PPM. The RTC clock source may not meet this requirement, leading to connection establishment failures, unexpected timeouts, or incompatibility with non-ESP peer devices.
