Flashing ESP32 using ESP32-S3

Hello everyone!
I have ESP32-S3 (host) that can be flashed through USB-UART, and two ESP32 connected to host. Is it possible to flash target ESP32 using ESP32-S3 via USB-UART?
Thank you!

Full duplex pipeline

Hello! I have pipelines like this: First LyraT: [bluetooth] --> [i2s], Second LyaT: [i2s] --> [bluetooth], LyraTs are connected via i2s so it's like a bridge between wireless headphones and smartphone. But there is a microphone in the headphones and I want to send sound back, so pipeline should look...

BT A2DP event handling

Hello everyone! I have bt -> i2s pipeline and i just noticed that i have a big delay between pushing stop button in my phone and real music stopping. I logged all events like that: void bt_handler(esp_a2d_cb_event_t ev, esp_a2d_cb_param_t* param) { gpio_set_level(DATA_PIN, dt); dt = !dt; ESP_LOGE(TA...

How to swap pipelines correctly

I have inited two pipelines: i2s -> bt and i2s_r -> i2s_w. When wire headphones are inserted I want to stop first pipeline and start the second. I wrote the code below: if(event->cmd == JACK_INSERTED) { ESP_LOGW("_periph_event_handle", "Change pipeline to i2s"); audio_pipeline_terminate(pipeline); a...

How to make two parallel pipelines

There is an example of parallel pipelines: https://github.com/espressif/esp-adf/blob/master/examples/advanced_examples/http_play_and_save_to_file/main/http_play_and_save_to_file.c I need to do the same thing, but bluetooth instead of http. So I have two pipelines: bt -> i2s and raw -> wav_encoder ->...

Re: What is the difference between LINE_IN and ENCODE/DECODE codec modes and how to play sound from AUX

Problem is solved. You should add lines below:

Code: Select all

audio_hal_ctrl_codec(board_handle->audio_hal, AUDIO_HAL_CODEC_MODE_BOTH, AUDIO_HAL_CTRL_START); // instead of AUDIO_HAL_CODEC_LINE_IN
es8388_write_reg(ES8388_ADCCONTROL2, ADC_INPUT_LINPUT2_RINPUT2);
es8388_write_reg(ES8388_ADCCONTROL1, 0x00);

What is the difference between LINE_IN and ENCODE/DECODE codec modes and how to play sound from AUX

I'm trying to send audio from i2s (AUX in) to bluetooth headphones. I made a pipeline i2s->bt, But if i type audio_hal_ctrl_codec(board_handle->audio_hal, AUDIO_HAL_CODEC_MODE_DECODE, AUDIO_HAL_CTRL_START); or AUDIO_HAL_CODEC_MODE_ENCODE , i hear sound from microphones, but not from AUX_IN. But when...

Is there a way to use esp32 as bluetooth host and client at the same time

I need to connect smartphone to esp32 and send audio stream, but esp32 I also want to connect with headphones and send audio. So for smartphone esp32 is client, but for headphones it is host. Is it possible to make two connections like this?
