This could be caused by bad power to the module as well. Make sure you have good 5V 500mA+ power going to it and that the cable used is good. When radio boots, there is a spike that will cause brownout if the ESP does not get enough power.

Do not symlink it.

you should disable mutextes by changing the option in tools/sdk/include/config/sdkconfig.h which is generated by menuconfig when libs are prepared in IDF. I will add it as option to the boards soon also. If you use Arduino the usual way and do not spawn threads or run code on both cores at the same ...

ESP32 Arduino currently comes with BLE support from IDF. Expect soon an Arduino-like class for easier access.

Yes, Arduino code has a bit different(simpler) requirements to run and as such implementing ISRs and other hardware trickery is pointless.

you can have a look HERE and HERE for example on how it's implemented in Arduino.

Ritesh, you can look into HardwareSerial.cpp as well and see what happens when you start arduino Serial :) it's pretty straight forward. #include "esp32-hal.h" uart_t* uart1; bool startUart(uint32_t baudrate, int8_t rxPin, int8_t txPin){ uart1 = uartBegin(1, baud, SERIAL_8N1, rxPin, txPin, 256, fals...

@rudi I especially committed a change so you can safely include Arduino.h in C files as well

you are trying to call CPP classes from C file You can use esp32-hal-*.h in C, the rest only in C++

@Ritesh esp32 Arduino can be used as an IDF component in your IDF projects, so you can access the drivers and familiar API from there while having full control of everything else. In the root of your project, create a folder named "components". Open terminal/console into that folder and git clone ht...
