Yes, please upload the bootloader.bin file which you are flashing using Arduino IDE.

Re: How to flash the ESP32 ?

Yes, that would work. Make sure you connect TX and RX the right way, and then ground GPIO0 and toggle EN before uploading. Make sure you connect EN pin of the DevKitC to ground, to keep it in reset.

Re: RTCWDT_RTC_RESET symptom of what kind of error?

I went through the schematic and didn't find anything that looked odd. Could you please upload the binary file(s) you are flashing to your board somewhere? At least the first one, bootloader.bin. According to the log (mode:DIO, clock div:1) the flash is clocked at 80 MHz. Maybe trying a lower freque...

Re: Cannot Start Task in ISR

The assumption is that esp_event_send is not called from an ISR. We can change it to use *FromISR version if you have a use case for calling esp_event_send from an ISR though...

Re: ESP-WROOM-32 EEPROOM?

Max size of a BLOB value which can be written into NVS is 4000 bytes. This value doesn't depend on total partition size. Also please update your copy of ESP-IDF and check latest documentation :) nvs_flash_init_custom function has been removed. NVS partition size is defined in partition table now, so...

Re: ESP-IDF 1.0 Release plan

Ritesh: "RF init and calibration data handling" has been merged into master a couple of weeks ago. This feature includes automatic calibration of ESP32 radio, and storage of calibration parameters in the NVS partition. This doesn't include any analysis features. It is also entirely unrelated to FCC/...

Re: Unable to read from BME280

I have moved this topic to Arduino forum.
Do you have a logic analyzer to check what happens on the I2C bus?
