Are you sure this is right?: if (sock != -1) { ESP_LOGE(TAG, "Shutting down socket and restarting..."); shutdown(sock, 0); close(sock); // mcarter 13-Sep-2019 err 112 fix. Ostensibly shutdown(listen_sock, 0); close(listen_sock); vTaskDelay(5); } I'm still having difficulties here. I will try recompi...

OK, I've assumed that the data needs to be as 16-bit ints rather than 8-bit ints. I've therefore created a main section that loops over the track endlessly: void app_main() { //int n=0; esp_err_t ret; static const int i2s_num = 0; // i2s port number static const i2s_config_t i2s_config = { .mode = I...

One thing occurred to me: is the reason that I can't set bits_per_sample to 8 because data has to be word-aligned, i.e. to even addresses?

So, I have a big block of data that I want to write to I2S. The data consists of 8-bit mono audio, sample rate 8kHz. I want the output on the DAC (pin 25). I figured that a way to do it is to write in blocks of 512 bytes using i2s_write(). However I am getting E (283) I2S: Invalid bits per sample wh...

And here's a video where I successfully stream audio over wifi using an ESP32-WROOM. A blinkt kit is included to give it a spiffy volume indicator. https://youtu.be/P5fPJ1hshdE

Thought you guys might be interested in a little gist ( https://gist.github.com/blippy/ee1b0f970c56d8eee7f54f796c5b20f1 ) I created to get audio playing on the ESP32 in the simplest possible way. It seemed pretty cool to me, anyway, as it's the first time I've got it to work. The gist contains a wri...

Everything "works", I get the responses I'm expecting, but I keep getting a watchdog timeout, and it's bugging me. I'm running out of ideas. Here's what's being reported: E (33283) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time: E (33283) task_wdt: - ID...
