Implications of customized system firmware - Photon

Hi, I had this working as a solution to have listening mode “timeout” after a set amount of time, but then recently updated to 0.4.9 and it no longer compiles. What is the simplest way to accomplish the same thing in 0.4.9? I don’t necessarily need much deliberate system threading in my application, but would that be the only way to do this now?

Have you checked your code against the docs?

My guess is the function signature has changed, from uint32_t to int.
