Re: Enabling Wifi breaks SD Card ability to read

The power supply is ok. I found today that I can stream data over wifi and save to the SD card over a non-secure HTTP connection. As soon as I switch to a secure HTTPS connection the SD card write fails. My SD card is connected to GPIO2, GPIO4, GPIO12, GPIO13, and GPIO15. Now these are also ADC2 pin...

Enabling Wifi breaks SD Card ability to read

ESP-IDF: 4.4.2 When I initialize the wifi and try to read from a SD card I get the following error. diskio_sdmmc: sdmmc_read_blocks failed (257) Without wifi it reads from the sdcard just fine. The SD card will still initialize fine. I (1274) SD_CARD: Initializing SD card I (1278) SD_CARD: Using SDM...

I'm running into a similar issue. Did you ever get this working?

Bluetooth blocking wifi check?

I am currently running the esp32 in dual BT/wifi mode. I've noticed that when the BT is listening for devices I cannot send data over wifi. I know BT and WiFi share the antenna, so it make sense that when one is using the other cannot. Is there a way to check to see if wifi can send data or if it is...

Re: Create audio pipeline with output to file and Bluetooth

For others that may have a similar issue and want to output audio to multiple elements, I found a solution that works. You cannot use the ESP-ADF pipeline. You need to go to the layer below the pipeline function and connect the elements with ringbuffers. This allows one of the elements to use "audio...

Create audio pipeline with output to file and Bluetooth

I am trying to setup a audio pipeline that will take input from the microphone(i2s) on a LyraT board and send it to some Bluetooth headphones along with converting it to a WAV and saving it to a file on the SD card. I can make a i2s-WAV-sdcard pipeline work successfully. And I can make a i2s-Bluetoo...

Re: Parallel output to components in the audio_pipline

I am looking at doing the same type of thing. i2s-->bt a2dp -->wav-->file. Have you found any way to do it? It looks like there can only be one stream writer at a time.

Re: A2DP_Source Example Pairing Bug

Found the issue. I had turned the main function into part of a C++ Class with the other functions remaining in their native C code. Although this did not throw any compile errors, it clearly broke something in how the C++ setup the bluetooth. I switched it back to native C and it works great.

A2DP_Source Example Pairing Bug

The esp-idf a2dp_source example will only connect correctly to an a2dp sink device(head phones) when the sink device is put into pairing mode first. After pairing to the ESP32, I should not need to be pair them again unless I erase the bonded device list. But there is a bug in the BT stack or in the...

Re: Classic BT previously bonded connection error

Maybe someone could help point me in the right direction with the callback functions for bluetooth. Using the example esp-idf a2dp_source I have the same issue. When the headphones are in pairing mode then bt_app_gap_cb(esp_bt_gap_cb_event_t event, esp_bt_gap_cb_param_t *param) gets called and state...
