Event Manager crashes in Submit Event

That's good to hear. Increasing the size of the buffer will fix it for now, but if you increase the amount of data over 100, it will happen again. A more permanent fix is to check the amount of data going into the buffer. Here are the changes necessary to app_module_event.c to do that:

Hi Mariano,

I solved this problem; I modified the array size as you recommended and it works, thanks!
I'm using the 1.9.1 SDK version.

Hi Ruben,

The code looks very similar to the way that Asset Tracker v2 is done. A few questions:

1) What is the array that you are trying to assign values to?

2) What version of the SDK are you using?

3) In src/events/app_module_event.c, in function log_event, can you try changing the size of the data_types buffer from the current 50 to something larger, like 100? This is not a recommended possible solution, but just to test if the buffer overflow is happening in this function.
