#lowpower — Public Fediverse posts

Timers seem simple until they cause mysterious power drain or timing issues. The JL JieLi AC696N SDK provides two timer systems with different characteristics. Here's what I've learned debugging on the dev board.

Practical Tip
Test both on the AC696N development board. Add serial prints to see which thread the callback runs in.

Both timer systems support one-shot timeouts—choose whichever fits your context needs.
