Thanks @MicroController ! That fixed it, I've tried adding 1 to the size, but at the wrong place :roll: So for future reference if anyone else encounters this problem, do not add 1 to the size while getting the certificate from nvs (in my code in esp_err_t get_credentials_from_nvs(char **cert, char ...

Hi, I've got a demo program running which communicates with AWS IoT Core using MQTTS and certificates generated by AWS. When the certificates are added to the firmware as binaries: target_add_binary_data(${COMPONENT_TARGET} "certs/certificate.pem.crt" TEXT) The code works without problems. In order ...

Hi all, I'm stuck on the same issue. Flashed the efuses (USB_PHY_SEL, DIS_USB_JTAG, DIS_PAD_JTAG) and afterwards I am not able to use GPIO41 as an output (which I was able to do before). Any ideas? Some observations: When connected to a 1M resistor to ground, the measured voltage over the resistor i...

So I got it working, but not on my laptop. I've connected the same device on a different laptop and there it worked without any problem: Connected the USB port and put the device in boot mode A COM port appeared on the device manager Flashed the eFuse without any problems Managed to upload the firmw...

Thank you for your response. I'm trying to burn the eFuse now, but I'm not able to run the espefuse.py tool on the USB-Port... (when board in runtime and in boot mode). I am able to run this tool when I connect to the UART-USB-Port, but I don't want that because my custom boards do not have an on bo...

Anybody?

Hi everyone, I'm trying to flash some firmware over DFU on the ESP32-S3-DevKitC-1, but I'm unable to do this, I keep getting No DFU capable USB device available CMake Error at C:/esp/esp-idf-master/esp-idf/tools/cmake/run_dfu_util.cmake:27 (message): dfu-util failed I've managed this before on the E...

Hi, I have a strange issue which is driving me mad. I'm experimenting with the device provisioning protocol: https://github.com/espressif/esp-idf/blob/master/examples/wifi/wifi_easy_connect/dpp-enrollee/README.md . Before implementing this in an existing project, I tried out the sample project on th...
