I'm currently testing a WmosD1 mini with the APDS-9960. I encountered the same problem like the Threadstarter - everything works only gesture test won't.
Directly after boot it runs into the interrupt and apds.isGestureAvailable() never returned a value.
How can I tell if the Wemos crashed or how can I further debug the LIB ?. I tried to use a capacitator in the 3.3V rail to stabilize the voltage this didn't help.
What else could be wrong.
Thanks
Stefan
