BMA456 Step Counting in 2's Multiple

[nafihahmd]

Hello,

Recently I am working with BMA456 for a smart watch project. I am unable to use the Bosch official API (That is amother question asked elsewhere in this forum). Mean while I got Library from Seeed Studio to working . Have a look at the Library I used Here. With it  I am able to read the step count but the problem is I am getting the step count in multiples of 2 ,i.e., 8,10,12,14...etc

Also oddly enough the step count always start from '8'.

It would be great if anyone here can shed some light to any of these problem. Thank you in advance

Hello  nafihahmd,

Simply, less walking might be confused with other activities like stand up. 

That's why we count walking activity after 7. 

So, you can see it after 7 ~8 🙂 

Please let me know if you have any questions 🙂

Thank you Minhwan. But why is the step counter incrementing in multiples of two? Why is it not out putting a resolution of 1. Is it because one arm swing is equal to 2 steps?

Hello nafihahmd, 

Right. generally, when we swing our arm one cycle, the step counting is 2. That's why it increases by 2. 

Of course, you can check 1 step if you do intentionally. 

Thanks 🙂
