I'm trying to use Serial2 and SD Card together but not at the same time but I noticed when SD Card is initialized, Serial2 (33/35) stops working and doesn't matter if I re-init the Serial2. I only need the SD card during boot time to read my config. I don't need it afterwards. Any suggestions?



In ESP32 there is good multiplexor, just set the serial you need to another free GPIO, not pins 33/35, and try again.

Switching to another pin did the trick. Thanks!
