I haven't solved this issue yet. I was able to connect at 48KHz SBC with my chromebook and my TV, so I know it can do 48KHz. I have tested many Android phones and IPhones and could only connect at 44.1KHz. I tried to use developer mode on the Android devices, but it always reverted back to 44.1KHz. ...

Using the A2DP-Sink project, I need to change the audio connection rate to 48KHz. I haven't had any success yet. It will only connect at 44.1KHz. Does anyone have any experience changing this setting?

Is it possible to receive audio from a bluetooth source (such as a phone) and re-transmit it out the Wifi interface via HTTP so that multiple ESP32 boards could receive/decode the audio? Basically I want to the ESP32 to bridge my audio out as an "internet radio" device (aac or mp3). Does anyone have...

Does anyone have any idea what this error means?

ASSERT_ERR((((uint16_t)clkoff1 << 0) & ~((uint16_t)0x000007FF)) == 0), in ld_acl.c at line 302

I don't have ld_acl.c source file in my SDK. I guess it's inside a pre-compiled library.

In case you are interested in developing ESP32 IDF projects on a PineBook Pro, it does work. I just had to compile the xtensa tools on the PineBook Pro first. I use the "make menuconfig", "make", "make flash", and "make monitor" commands to configure, build, program, and monitor debug output from my...

I am using GPIO36 as a button input. It normally works fine. If I enable bluetooth audio I notice very fast pull-down pulses. These pulse occur about 0.5sec rate when BT A2DP isn't connected to my phone. When it initially connects to my phone, the glitches still occur at the same rate. If I then sta...

Is it possible to have both an A2DP and a HFP connection to a phone at the same time from the ESP32? I currently have firmware written that uses A2DP to stream audio to a speaker. I now need to be able to periodically send the speaker's battery level information back to the phone while audio is stre...

I was incorrect. The I2S glitching still occurs whenever you resume audio playback after A2DP has been suspended (takes about 4 seconds to suspend after pausing audio when using Android device and about 1 minute to suspend when using IOS device). I have tried numerous things to fix this issue for th...

I can't send code onto the forum per my company's privacy policies. This issue appears when building with IDF Version 4.0 with VisualGDB GUI on Windows 10. Today I installed "master" (ESP-IDF v4.2-dev-459-ge36516372-dirty) version of IDF onto my Linux machine and found that I now only have a small g...

I am randomly getting audio data glitches during initial playback of audio. It appears to be "random". Sometimes it doesn't occur, sometimes it does. I can't figure out why this is happening. I'm not getting any errors reported via the serial debug interface. Any suggestions? After about the first 1...
