nRF8001 slave latency vs connection interval

[PhilippS]

Hello!

I have a question about the slave latency: I know how it should work, I would like to know if it is normal that there are current peaks in the supply current when a connection event is skipped? See the figure below, there are 2 high peaks which indicates a connection event, and between there are the connection events which should be skipped but there are still current peaks. Is this behaviour normal?

If yes, increasing the connection interval would be better to reduce the average current consumption than using slave latency. Is that right?

Another question about the current consumption: Would using the active signal increase the power consumption of the nRF8001?

Thank you very much!!

Hi,

If I remember correctly the nRF8001 cpu will be woken at the connection events, but the radio will not be started when slave latency is used. Increasing the connection interval will give you the lowest current consumption. Not sure how much the active signal will affect the current consumption. depends a little on the load.

Regardless I would recommend that you look at one of our later products as those have lower current consumption, higher processing power and usually also a lower price.

Hi,

thank you for your explanation, much appreciated!

I cannot replace the nRF8001 but I will look at later products for my next project.
