Calculation Formula:
Max Throughput = (Packets/Event × Payload Size × 8) / Connection Interval
Effective Throughput = Max Throughput × (1 - Error Rate) × Efficiency Factor
Max Throughput = (Packets/Event × Payload Size × 8) / Connection Interval
Effective Throughput = Max Throughput × (1 - Error Rate) × Efficiency Factor
Note: These calculations represent theoretical maximums. Real-world performance may be lower due to:
- Radio interference and environmental factors
- Device processing delays
- Stack implementation efficiency
- Power saving modes and duty cycling

Factors Affecting Speed
Optimization Tips
Theoretical vs Practical
Theoretical throughput represents the maximum possible data rate based on your parameters, while practical throughput accounts for protocol overhead, acknowledgments, and real-world inefficiencies. Expect practical speeds to be 50-90% of theoretical maximums.
Factors Affecting Speed
Key factors include: PHY selection (1M vs 2M vs Coded), connection interval (lower = faster but more power), MTU size (larger = less overhead), packet error rate (interference), and transfer type (notifications are fastest).
Optimization Tips
For maximum throughput: Use 2M PHY when possible, negotiate larger MTU (247+ bytes), enable Data Length Extension, minimize connection interval, use notifications or writes without response, and ensure good signal quality to minimize errors.
