useRmtInternalLoopback()

bool fl::validation::useRmtInternalLoopback ( bool is_rmt_driver, int tx_pin, int rx_pin )

inline

Whether an RMT validation capture should use ESP-IDF loopback.

ESP-IDF's internal RMT path only connects TX and RX channels configured on the same GPIO. Distinct pins require a physical jumper and must leave the RX channel attached to its external GPIO input.
