esp-idf VS ESP32-A2DP

IDF contains stuff like https://github.com/espressif/esp-idf/blob/master/pytest.ini and https://github.com/espressif/esp-idf/blob/master/tools/ci/idf_pytest/constants.py which are not part of the pytest-embedded package.

ugh.. arduino.

Better to start with ESP-IDF, there's a pretty full featured well documented web server, and a lot more.

Hi, I have device ESP32-S3-DevKitM-1 and i want to catch keystrokes from keyboard. I tried using this https://github.com/tanakamasayuki/EspUsbHost and example from espressif https://github.com/espressif/esp-idf/tree/release/v5.1/examples/peripherals/usb/host/hid/main but when i connect keyboard it is just connecting and disconnecting. Can anyone help me with this?

According to this page, coexistence of WiFi and 802.15.4 is now supported. Thread is based on 802.15.4.

The example: https://github.com/espressif/esp-idf/tree/master/examples/openthread/ot_br "The example could also run on a single SoC which supports both Wi-Fi and Thread (e.g., ESP32-C6), but since there is only one RF path in ESP32-C6, which means Wi-Fi and Thread can't receive simultaneously, it has a significant impact on performance. Hence the two SoCs solution is recommended."

The latest, but it was a few months ago. The results were off by 400 meters, and many persons have the same problems : https://github.com/espressif/esp-idf/issues/8976

Use an official I2C example form the IDF. Like this: https://github.com/espressif/esp-idf/blob/master/examples/peripherals/i2c/i2c_simple/main/i2c_simple_main.c I’stand corrected with respect to the call order, it appears the driver install comes later. Your speed is unusually low, use the default speed of 400K. If you still get the error in the setup, use the source: the IDF is fully source distributed. Look into the implementation of the function, which errors occur form which code parts. Use ESP_LOGE or similar calls to get output messages on where you are getting to within the code. So that you learn where it’s expectations aren’t met.

You'll need the core dump and the ELF file, assuming you have them both, you will need espcoredump.py (Github), but it's easier to install the whole ESP-IDF (docs.esspressif.com) package as the coredump tool has dependencies.

Check out arduino-audio-tools and other libraries it can make use of, such as ESP32-A2DP. It's tailored towards ESP32 devices, but also supports the RP2040 and others.

For all other i2s pinouts, I'm leaning on this GitHub-project: https://github.com/pschatzmann/ESP32-A2DP

You can use Bluetooth A2DP. This is the same standard used in Bluetooth headphones. Several implementations are available https://github.com/pschatzmann/ESP32-A2DP

https://github.com/pschatzmann/ESP32-A2DP/issues/149 Seems to cover this for esp32 but form the information 16bit vs 32 bit a2dp does not effect the audio quality just the things it can connect too?

That project is inspired by KitchenRadio and uses ESP32-A2DP library ! 🙏

I would look this way for a simple implementation : https://github.com/pschatzmann/ESP32-A2DP

where a2dp_sink is an object of type BluetoothAudioSink and audio_data_callback(const uint8_t *data, uint32_t len) appears to be a member function. That class is found in a different project at ESP32-A2DP

Interesting project. Do you have an idea of the microcontroller you want to use? ( I wonder if something like this would be useful ... https://github.com/pschatzmann/ESP32-A2DP ) Is that something you are going to do solo or are you going to publish somewhere? ( I am thinking about hackaday/github)
