Connection Interval 's relationship with Data rate and power consumption

[Ziyao Zhou]

Hi

I noticed one ticket says that "the following combination offers low power consumtion and high througput when needed :Short Connection Interval + High Slave Latency + Long supervision timeout "

I try to study this in two nRF54L15 DKs, I will change the connection interval in 

	struct bt_le_conn_param conn_param = {
						.interval_min = 320,
						.interval_max = 320,
						.latency = 0,
						.timeout = 4000,
					
				 };

The result is like， where thee blue curve is throughput. the orange one is power. I notice there is no clear relationship.

Could you kindly give me some evidence that shows Short Connection Interval + High Slave Latency + Long supervision timeout is nice choice?

Careful: BTLE is not intended for high data rates.

Your throughput is only achievable with close to 100% radio on-time, thus you will see basically the same current consumtion over a large parameter range.

Does your application really need those rates? Then BTLE may not be the best choice.

Thank you for your information! Yes, I am using BLE to do video transfer. So that if I use low throughput appliacation the interval will have difference?
