Hello,
I'm working on a project to increase the detection range of the STHS34PF80. During my tests with different LPF and Threshold settings, I noticed that TPRESENCE_L often drops to 0 and stops updating entirely.
It feels like the internal algorithm is "absorbing" the signal or the filter is too aggressive.
Does changing LPF settings require a specific reset sequence to prevent this?
Are there known limitations when trying to push the range beyond 2.2m using software parameters?
Any help would be greatly appreciated. Thanks!
