Hi everyone building my C firmware as C++ I'm stumbling on these errors which come from a MACRO in esp_attr.h ~/esp-idf/components/xtensa/include/esp_attr.h:110:34: error: conflicting declaration of C function 'constexpr timer_intr_t operator~(timer_intr_t)' ~/esp-idf/components/xtensa/include/esp_a...

In light of your observation I headed to the second possible culprit and I think I solved it. the sparkfun uses the ftdi serial adapter which runs on the 5v of the usb, while all of my other boards use the cp210x which run on the 3.3v from the LDO (these serial adapters when active draw around 100uA...

I also see this problem. The only board I have which doesn't present this problem is the "ESP32 SparkFun Thing". The only meaningful difference is that the sparkfun has a 26MHz quartz the others 40MHz. I know that many quartz draw a lot of current but could anyone post the dataheets for the SparkFun...

Hi all! ~~~~~~~~~~~~~~~~~~~~~~~~ This issue was solved by enabling SO_REUSEADDR in config ~~~~~~~~~~~~~~~~~~~~~~~~ I'm porting some code from Arduino IDE to ESP-IDF using Arduino component. The code sends UDP packets collected from sensors to a connected client. Also it listens on a port for UDP pac...
