Hardware RTC Compensation Latency versus Sensor Mass Lag in Rapid Thermal Gradients
RTC compensation latency during thermal transitions causes clock frequency drift, requiring wider radio receive guard windows that drain battery reserves.
BLE Connection Interval Sync
Meaning
Temporal alignment between a central device and a peripheral for periodic radio frequency exchanges. Data transfers in a ble connection interval sync depend on both radios waking up simultaneously at the start of each window. This mechanism maintains the link without constant scanning.
Timing Maintenance
Procedures for clock correction ensure the peripheral tracks the timing of the central node. Radio packets contain timing data that allows the slave to adjust its internal sleep timer. High accuracy sleep crystals reduce the required window for ble connection interval sync events.
A drift in the local oscillator requires the receiver to stay active for longer periods to avoid missing the start of the transmission.
Link Stability
Stability during long sleep cycles prevents the peripheral from missing the start of the scheduled window. If the ble connection interval sync fails due to clock skew, the peripheral must perform a wide scan. This recovery process consumes significant battery power compared to standard synchronized events.
Packet Throughput
Successful synchronization allows the system to maximize data transfer during the short active periods. Multiple packets may be exchanged during a single ble connection interval sync before the radios return to a low power state.
