I have a PCB that connects an external Reset and Setup buttons to the Photon SMD. Most of the time they work fine, but I can tell there is a time delay (~1/2 second) of pressing the external buttons vs. pressing the buttons on the Photon.
This becomes an issue when trying to put the Photon in
Safe Mode or ``DFU mode
. Only 1/3 of the time the Photon responds correctly to pressing both buttons. The rest of the time it will reset, but then it ignores that you are still pressing the Reset button and it will enterListening mode
instead ofSafe Mode```.
Below is the schematic of the PCB. I could really use some help here. Any idea what I’m missing?
