I had the exact same issue - hopefully Espressif reply and take some responsibility for changing how different batches have different requirements for boot mode and strapping pins

https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/api-conventions.html#configuration-structures Also esp_now_send return value only indicates that the packet was internally queued successfully. You need to use the send callback to determine the outcome of sending it. It work...

SOLVED It works now! Turns out updating my toolchain, the wireless coexistence was set to being controlled by software which I was able to change from menuconfig Hi everyone, Since migrating my toolchain from IDF 4.3.1 to 5.1.2, I've had several fun changes I've had to make. None have been quite as...

I really appreciate the reply!! With this ESP32-C3-Mini-1 module on the IDF4.3 toolchain there were no issues, so I assumed the SOC supported it. In the newer 5.1 toolchain, in the esp-idf/components/soc/esp32/include/soc/soc_caps.h file these parameters are defined and permitted (shown below). /*--...

I'm currently in the process of migrating my IDF tool-chain from version 4.3 to 5.1.2. Generally, the migration guides and API guides online have been really helpful and the inclusion of additional header files, changing some syntax and adding requirements to CMakeLists.txt have done a lot of the le...

Hi All, I have been using an ESP32-C3-Mini-1 module in my design, and have been using USB connection only to flash firmware and monitor the microprocessor. Recently, I had new PCBs manufactured with the exact same design I have been using and am now unable to flash or monitor the device. The old wor...

@cyber_v1 very interesting. May I ask how you interfaced with the chip? Was it over USB or UART/JTAG? Do you have a date code? I removed the front cap of our modules and found the units that do not function were manufactured in 2023, while the working units were made in 2021. On the front of the mod...

I have had the same issue however have not been able to pull GPIO2 down. I have had our devices with modules marked XXN4 function fine, however when attempting to flash new devices (exact same PCB design) with modules marked M4N4, I get the error "Errno 32: Broken Pipe". We are also using USB to con...

Hi all, I don't mean to add to any necessary hysteria, but I ordered 30 PCBs from PCBWay of a design we have always had PCBs of who confirmed they ordered the device's ESP32-C3-Mini modules from LCSC, and I have had the same issues. For added context, my flashing method is below: - We flash over USB...
