Understanding of the debug() Function

[YueLink-hi]

Hello, what are the differences among the three printing functions: debug(DBG_INFO, , );, debug(DBG_OFF, , );, and printf();? Why can't debug(DBG_INFO, , ) print anything, and under what circumstances does this function effectively print? What about debug(DBG_VERBOSE, , )?

debug function first argument is (log)level. DBG_INFO is 1. you can send command loglevel=1 over console to enable prints of that level. You can enable multiple logs e.g. to enable DBG_INFO and DBG_VERBOSE, send loglevel=1,2
