I have a ESP-IDF project which was made with ESP-IDF 4.4.2, it had arduino as a component, https://github.com/espressif/arduino-esp32.git, when i look at the commit I have checked out for the arduino component it is dated 3rd OCt 2022 6f0c55e0 I have recently checked out the project onto a new machi...

Hi,

For the ESP-C3-mini-1 SOC we would like to scan the QR code in order to identify each chip.

When we try and scan it we do not have any success, can you recommend software that we should use to scan it?

Thanks

So to calrify, you suggest holding GPIO9 low then performing a reset of the mcu? I.e. instead of the DTR and RTR lines putting the unit into boot mode on the programmer you suggest I do it manually? I will have to try that Monday. Here is the reset pin on the board getting flashed and the RTR and DT...

WE still have the same problem and are having to bin about 1 in 10 boards, this is no good for any sort of production, is there a way to raise the priority of this? Could someone explain what causes the following errors? ESP-ROM:esp32c3-api1-20210207 Build:Feb 7 2021 rst:0x1 (POWERON),boot:0xe (SPI_...

Thanks for the reply I can't see how that will help me because most PCB's are fine, there is no way of knowing which one will fail. I did manage to check one prior to flashing that failed, and recieved the normal invalid header 0xfffffff before flashing... When i tried to flash it it failed and the ...

I have a load of identical PCB's with an ESP32-C3 on. I'm using the factory flash tool, I'm using a mass programmer, the USB to serial chip is offboard and the unit is programmed via spring loaded pins Most Boards flash fine, others don't, when I look at the ones that don't over the serial port I ge...

Hi, On ESP32-C3 I have it setup as: Single app not OTA 0x8000 offset of partition table flash encryption is set to release mode When I use flash to v3.9.3 and set it up as follows: esp32FlashTool.png ...and press start, it appears to flash the device from the loading bar at the bottom, but it doesn'...

Thanks for your reply, the examples there are for advertising and a security server. I'm not bothered about implementing the security server part just a server for now. Are those settings all that are needed to enable the long range features of ble5 in server mode? Is there any change in settings fr...

Hi, I'm interested in increasing the BLE range of the ESP32C3 and I am a little confused about BLE 5.0 vs 4.2, as I understand it BLE 5.0 is longer range. Is BLE 5.0 purely a hardware level change (that the programmer does not see) or are there software level changes? I notice there are configuratio...

I notice the supply for the RTC is also connected to the general 3V3 supply on the schematic for the ESP32-C3-MINI-1-H4 module. If i supply 3.3V power to the ESP32-C3-MINI-1-H4 but have the enable line low, so chip disabled, will the RTC keep on running if it has been set previously? Or for the RTC ...
