Greetings, We'd like to increase the baudrate of our communication between the host and the esp32c3 (v2.4.2.0) after the system boots. The default speed is 115200 and this works OK. We can verify that the host is able to change baudrate correctly by inspecting the signals on an oscilloscope. When we...

We notice that SYSMFG is not listed in the output of AT+CMD?. What do we need to do to enable this command?

Greetings, Using an ESP32, I have GPIO inputs on pins 26, 27, 14, 34, 32, and 35. I am using this code snippet to enable interrupt handlers: void enable_button_input_isr (gpio_num_t gpio_pin, void* pvUser) { { gpio_config_t config = {}; config.intr_type = GPIO_INTR_ANYEDGE; config.pin_bit_mask = 1ul...

Call me crazy if you like.

Wouldn't it be a low-cost feature to simply report an error instead of crashing?

Greetings, I am using the BluFi app on IOS to test the setup of WiFi using this protocol. The WiFi setup appears to work as expected. When I configure the SSID and password via the APP, the ESP32 connects to WiFi as expected. We also want to use the custom data feature to send information from our A...

One other thing. We poll for partitions: at+sysflash? +SYSFLASH:"ble_data",64,1,0x1f000,0x6000 +SYSFLASH:"server_cert",64,2,0x25000,0x2000 +SYSFLASH:"server_key",64,3,0x27000,0x2000 +SYSFLASH:"server_ca",64,4,0x29000,0x2000 +SYSFLASH:"client_cert",64,5,0x2b000,0x2000 +SYSFLASH:"client_key",64,6,0x2d...

Greetings, We are using the ESP32 AT command firmware, v2.4.2.0 on the C3. We made a small change to the configuration to select the pins for the serial port. Otherwise, the configuration is 100% vanilla. We'd like to use the AT+SYSMFG commands. The documentation states that this should return a nam...

Greetings, We are attempting to build the AWS IoT sample. We cloned this repo: https://github.com/FreeRTOS/iot-reference-esp32c3/blob/main/GettingStartedGuide.md We followed the instructions: git clone git@github.com:FreeRTOS/iot-reference-esp32c3.git --recurse-submodules git submodule update --init...

When I invoke nvs_flash_init(), the program crashes. Without this call, it doesn't. I don't think this call, specifically, is the problem, but I can see that adding just this one call is enough to make the program crash. The stack backtrace shows that these is the problem instructions: 401019bc <adc...

That was the issue. Setting the baudrate to 230400 works. The espressif documentation has this as an explicit example: esptool.py -p PORT -b 460800 read_flash 0 0x200000 flash_contents.bin See https://docs.espressif.com/projects/esptool/en/latest/esp32/esptool/basic-commands.html#read-flash-contents...
