Hi, I’m currently trying to use the RTL8720dn chip as I2C Slave. I’ve tried using some functions and implementations of the sdk (i2c_api), but facing some weird issues where the polling mode doesn’t seem to work. Because of this, I’m curious if the Arduino package contains the full implementation. …

[image] luke: using this example has not provided the expected function when using the corresponding Master program. could you elaborate on your settings? You can refer to this example guide for detailed steps and demo
