Re: getting error "undefined reference to" when linking the firmware

Thank you @MicroController I was missing the "extern C" on the .h of some of the components.

getting error "undefined reference to" when linking the firmware

Hello, I'm having issues getting started with ESP-IDF programming, more specifically with CMake and building.
I come from developing using ESP-IDF with PlatformIO, after encountering some unsolvable issues when trying to use some IDF components, I tried them examples in IDF and worked very well.
Now ...

Re: idf.py menuconfig ignore keyboard input in powershell/cmd on windows 10

Have you tried using J and K to navigate?
Seems silly to ask, but it had me going for sometime until I found out that menuconfig doesn't uses arrows anymore

Re: i2c_master_probe doesn't send any data, it just timeous out

Finally, I discovered that the actual address of the device is not 0x58 (its 0x59) and my real problem with the communication was due to bad pin connection between the ESP and the DAC IC.
Although I never found out what was the problem with the i2c_master_probe function, my real issue was fixed ...

Re: i2c_master_probe doesn't send any data, it just timeous out

Hello dmitrij999 , thank you for your response.
It took me some time to familiarize with it, but here is the result.

It seems to detect a device in the 0x58 I2C address, I need to keep investigating.

Thank you for pointing me to something useful, I'll share any ...

i2c_master_probe doesn't send any data, it just timeous out

Hello, I'm having issues when connecting an I2C device to the ESP32S3 module.
First, a bit of context:
- Using ESP32S3-WROOM module, programming in VSCode using Platformio with ESP-IDF last stable version 5.4.
- The I2C bus has 3 different sensors attach to it: LIS3DH accelerometer (0x19), OPT3004 ...

Re: OTA BLE and BLE SCAN at the same time, is it possible?

Thank you both for your input.
I ended up having to scan for a specific UUID that works as a "here comes the OTA" message to deinitialize all the BLE-SCAN implementation. Once BLE-SCAN is stopped and everything is deinitialized, I start the BLE-OTA task.
It's a very silly solution, but it kind of ...

OTA BLE and BLE SCAN at the same time, is it possible?

Hello, I'm developing an esp-idf application for the ESP32-S3 module using platformio in VSCode.
I've tried the OTA BLE component succesfully, following the example from the https://github.com/espressif/esp-iot-solution/tree/master/examples/bluetooth/ble_ota repository.
It works very well, however I ...

Re: SPI not workin, help needed

Looks like my logic analyzer can't reach further than 500kS/s

So I tried lowering the clock speed of the SPI device to 100kHz, same as I2C that I have already working with the logic analyzer.
This change made the singals appear correctly:
