Re: Unable to select board "ESP32 Arduino" on Arduino IDE although the menu item is there

Hi, I am selecting "esp32 dev module". It brought some issues to our development, but haven't blocked ours :-) So, you could put the case into a lower priority for the time being :-)

Re: "Guru Meditation Error: Core 0 panic'ed " happens when using "WiFi"

Hello, have you REPRODUCED the issue? Please notice that the issue happened in a "standard" Arduino example calling "WiFiClient". If it is a real bug with ESP-Wrover_kit dev board, it will really impacts developers' confidence to implement WiFi-related app on the board :-( Thanks!

Re: Failure with flashing esp-wrover-kit dev board under Arduino-esp32

Hi krzychb, Your guidance is really helpful! The esp-wrover-kit dev board has been proved to work under EspArduino environment. My first evidence was got through the following steps. 1, The new actions should be taken based at all procedures ahead that I listed yesterday. Those include cloning ardui...

Re: Failure with flashing esp-wrover-kit dev board under Arduino-esp32

Hi krzychb, I have just taken the following actions. 1, copied esptool.py from esp/esp-idf/components/esptool_py/esptool to ~/Arduino/hardware/espressif/esp32/tools, and changed DEFAULT_PORT to /dev/ttyUSB1. 2, cd makeEspArduino 3, make -f makeEspArduino.mk ESP_ROOT=~/Arduino/hardware/espressif/esp3...

Re: Failure with flashing esp-wrover-kit dev board under Arduino-esp32

Thanks for your rapid feedback. To keep the serial port as same, I changed the DEFAULT_PORT of USB port name from /dev/ttyUSB0 to /dev/ttyUSB1 in esptool.py. Let me try esptool.py v2.2.1 to arduino-esp32, to see what will happen :)
