help
BLE Sleep Clock Accuracy(SCA) for the local device is used to estimate window widening in BLE
connection events. With a lower level of clock accuracy(e.g. 500ppm over 250ppm), the slave
needs a larger RX window to synchronize with master in each anchor point, thus resulting in an
increase of power consumption but a higher level of robustness in keeping connected. According
to the requirements of Bluetooth Core specification 4.2, the worst-case accuracy of Classic
Bluetooth low power oscialltor(LPO) is +/-250ppm in STANDBY and in low power modes such as
sniff. For BLE the worst-case SCA is +/-500ppm.
- "151ppm to 250ppm" option is the default value for Bluetooth Dual mode
- "251ppm to 500ppm" option can be used in BLE only mode when using external 32kHz crystal as
low power clock. This option is provided in case that BLE sleep clock has a lower level of
accuracy, or other error sources contribute to the inaccurate timing during sleep.
