lower power consumption ant and ble

[Matthias]

Hello,

i have an application that sends periodically sensor data from one sensor network (6 sensors - 16 Bytes) to a host f = 1/4 - 20 Hz. I read the s210 and s110 SDS but in 210 on page 40 the diagram says at the x-axis "Sample Num(50 kHz rate)" Could you please tell me what time base that is? Or how long it tkaes to send 16 Bytes over Ant and how much energy it approximately takes?

Thank you a lot! Matthias

Hi Matthias

Thank you for your observation.

The x-axis label and scale in figure 12 of S210 Softdevice Specification v2.0 does not make sense to me either. I know for a fact that from the beginning of (A) until beginning of (D) is 1.5ms. So if we replace the x-axis values in the following way:

50 with 1 ms
100 with 2 ms
150 with 3 ms
...

then it seems to be more or less correct. I have reported this as a documentation error.

Thank you a lot! Well, somehow it works with that axis description: If you do it like x/50k you get for 150 the 3 ms, but i wasnt sure i i did it right that way. now i'm sure and can continue working.
