Movement Threshold

[mpo881]

I have read that the threshold value for movement is 64mg

Position or rotation sensing?

Is RuuviTag device supposed to detect position/rotation or just acceleration/movement? I attached the device to the top right corner of the door. So the device is in vertical position (like car tyres when rolling). When I open the door (90 degrees) the AccX/Y/Z values in the Ruuvi Station app are about the same in the end.

I would like to experiment with different values if that is possible. Are there set values that can be used or can it be any assigned value? Where is this value changed in the firmware prior to flashing the updated value?

Thank you in advance

ok so I want to change the value of 64 to make the LIS2DH less sensitive. Do I change the define scale or the define activity threshold value? If it is the activity threshold value, what values are acceptable to use? Where exactly do I change it in the firmware? How do I flash the changed firmware?

Any help appreciated

#define LIS2DH12_SCALE LIS2DH12_SCALE2G
#define LIS2DH12_RESOLUTION LIS2DH12_RES10BIT
#define LIS2DH12_SAMPLERATE_RAWv2 LIS2DH12_RATE_10
#define LIS2DH12_SAMPLERATE_RAWv1 LIS2DH12_RATE_1

// mg, scaled to bits by driver
#define LIS2DH12_ACTIVITY_THRESHOLD 64

At the present time you need to generate your own firmware using the information found at Firmware_README.md

I would appreciate it if you could describe your use case. Perhaps I could offer another suggestion If I understood what you need to do.

I believe you are looking at version 2.5.x since
LIS2DH12_ACTIVITY_THRESHOLD is no longer used.

@dgerman thank you for the reply. I have a gateway that collects the data from Ruuvi and sends notifications, etc to the end user. In this case I am receiving movement data but the default setting is too sensitive. I would like to make it less sensitive.

Since you have pointed out that the movement threshold is no longer used, I would imagine then I would have to change the G scale to 4, 8 or 16?

Thank you

I did not say the threshold is no longer used ,rather that it is done differently in the current 3.3x.x version.

Noted. I incorrectly stated “movement threshold” instead of what you did say which is “activity threshold”

This is my use case. Not sure what else you are looking for

Thank you

I am just trying to get an idea of what “data” you are collecting and what “notifications, etc” you are sending.
Like “bicycle monitoring for theft.”
“gate movement to detect runaway goats”
If it is proprietary of confidential then oK.
