Hi

I have bought the BLE Cap sense and try to add the touch panel in the existing switch panel,

the overlay of the touch panel is a combination of metal and plastic, I need to increase the sensitivity with a range of 1cm.

If it increases to 1 cm the metal also behaving as a touch.

Kindly suggest how to control this.

I want to set the sensing level about 1 cm above from the touchpad.

Regards

Hi Imroze,

Please note that the overlay used for CapSense sensors should be di-electric. Else, you will see false triggers or degradation of performance. Kindly check if you can change that.

I think you need to do some manual tuning to find the trade-off betwen requirement and over sensitivity. Please refer the Capsense manual tuning section 5 from the document below:

Please attach images of your board for more understanding.
