Stuck in GPIO interrupt during init

Button 1 using pin P0.11 which is also TRACE DATA 2. I guess you find the root cause.

I'm pretty sure this has to do with the fact that we are using the 20 pin trace debug port. I'm going to try and figure out how to switch the buttons over to the alternate.

The pin on the micro is normally at 1.5v until the switch is closed, in which case it goes to 0v. I'm guessing it should be at 3.3v, so it is indeed floating?

I mean have you checked what the actual voltage level of the pin connect to the button.

You can try to test without starting the mesh stack, just check what triggers GPIOTE_IRQHandler(). Note that the PORT event only triggered on the rising edge of the DETECT signal. I'm suspecting there is one of the pin staying float and trigger lots of event ?

1. PCA10056

2. It's button 1. How can I check the level of the button?

3.I'm trying to replicate the MESH light_switch provisioner example. Runs just fine in SES, but we are trying to get away from it.

Hi,

Which hardware board did you use for testing ?

Which button did you have the issue ? Have you check the level of the button ?

Have you tried to compile using Segger Embedded Studio ?
