Switch between SD-Player and ESP32-A2DP with tasks about arduino-audio-tools HOT 32 CLOSED

It doesn't crash anymore when I do SPI.end(); Still the a2dp won't start because I can't detected it.

from arduino-audio-tools.

I tried to following link to make a beter spi connection

https://www.pjrc.com/better-spi-bus-design-in-3-steps/

But still I can't make it work. What I could do is to surpress the multi spi devices and test with only the sd card reader and the A2DP. An other thing would be that I use a card reader that is ment to work on 3.3v. But I m waiting on my order for now.

on boot I work with the SD player of audiotools. After a button is pushed I turn off the player and start A2DP but it won't start.

This is how I end it and giving me the best result for now.

	player.end();
	SPI.end();
	//i2s.end();
	Serial.println("activate A2DP");
	//a2dp_sink.set_avrc_metadata_callback(avrc_metadata_callback);
	a2dp_sink.start("BluetoothSpreaker");
	Serial.println("A2DP active");

from arduino-audio-tools.

Just found out that it's not the the a2dp sink that won't start... It's the spi that won't end.

It's this line spiStopBus(_spi);

from arduino-audio-tools.

cann't end the spi because of the sd player. Could be a hardware issue. But when I leave the player out it still crashes when I try to begin A2DP. I think I need to start a project with only the a2dp library and the sd player to clear this out.

from arduino-audio-tools.

I committed some corrections and I think I have it working now.

• A2DP do not try to reconnect when end is in progress
• AudioSourceSdFat AudioFs sd is initalized only once

from arduino-audio-tools.

You forgot the revert the config file.

#define I2S_BUFFER_COUNT 20 // 20

from arduino-audio-tools.

Corrected

from arduino-audio-tools.

I mad a new project with only the sd player and the esp32-a2dp. now it works without close down the sd player. I have added a the other library I m using in the other project and it still works. I am thinking of the task I have created to solve the memory issue are the problem to start the ESP32-A2DP sink.

This was the error I was getting...

The esp exception error descriptor comfirms with what I m thinking. Is there an interfering with my task in the shetch and ESP32-A2DP library?

from arduino-audio-tools.

I don't know your code, so it's difficult to say. In the A2DP library there is a task which is dispatching the messages.

from arduino-audio-tools.

I have added the task to my new created project and this is what I found out. There are two reasons why it crashes with the esp32-a2dp library.

1/ To small delay in the loop
2/ To high stacksize in the task

After trying to optimize it, I can connect with my phone to the esp32, but after that it crashes again.

Strang test results:
Stacksize on 50000 = crashes immediately
Stacksize on 30000 = crashes immediately
Stacksize on 10000 = crashes after connecting (PortGetFreeHeapSize: 178992)

I suggest that you also activate the ESP32 error Logging.
You can't start the A2DP Sink and I2SStream at the same time and I would expect that you see plenty of Error Messages in the log. You either make sure that only one or the other is started or you deactivate I2S in A2DP and use the I2SStream via a callback (see my example https://github.com/pschatzmann/arduino-audio-tools/tree/main/examples/examples-audiokit/player-sd_a2dp-audiokit)

But I don't think this is the source of your issues. Some more thoughts:

• Since A2DP is running it's separate task I would take it out of your task and use it only for the player.
• I am also wondering what forced you to use your own task in the first place ?
• I think the default stack size is 8192 - can it be that you are running out of heap ? and A2DP just has not enough memory left to start...

Maybe you can try out my player-sd_a2dp-audiokit example. Just replace the kit with a I2SStream.

from arduino-audio-tools.

• I am also wondering what forced you to use your own task in the first place ?

I started it when I was working with the sd player. This is only a fraction of my project. My project is hugh and I could only have the default loopstack of 8192, that was to low.

Strang test results:
Stacksize on 50000 = crashes immediately
Stacksize on 30000 = crashes immediately
Stacksize on 10000 = crashes after connecting (PortGetFreeHeapSize: 178992)

The reason that I could not increase the stack was because it has to be defined like this.

#define LOOP_STACK_SIZE 60000

and than added in here, instead of writing a number in here.

	xTaskCreate(
		Task1code,   /* Task function. */
		"Task1",     /* name of task. */
		LOOP_STACK_SIZE,       /* Stack size of task */
		NULL,        /* parameter of the task */
		1,           /* priority of the task */
		&Task1);      /* Task handle to keep track of created task */

You can't start the A2DP Sink and I2SStream at the same time

Humm... I'm not using the I2S as an input, I am using it as an output. deactivating the I2S I could not do because I need it to output to my spreaker. It could be if it's used as input and that those cann't run at the same time.

https://github.com/pschatzmann/arduino-audio-tools/tree/main/examples/examples-audiokit/player-sd_a2dp-audiokit)

This will help.

• Since A2DP is running it's separate task I would take it out of your task and use it only for the player.

Soo use the buttons to start 1 task for A2DP and 1 task for the player?

from arduino-audio-tools.

I did the player.end() but still getting stuck by starting the A2DP on this line: init_bluetooth(); line 276

    if (esp_bluedroid_init() != ESP_OK) {
        ESP_LOGE(BT_AV_TAG,"Failed to initialize bluedroid");
        return false;
    }

from arduino-audio-tools.

In Arduino you activate the logging in Tools -> Core Debug Level. I still think that it will be pure luck if you have 2 functionalities running the I2S output setup - One of them will fail - and it is not really defined what will happen.

I am still of the opinion that most likely you are running out of heap: You can easily verify this by moving the Bluetooth initialization before the player. Then bluetooth might work and the player might fail.

I would also suggest that you double check your local variables which are the source of trouble in the first place. Usually you only need a big stack if you have recursive methods. But I assume you use manly arrays that you could put on the heap.

from arduino-audio-tools.

Just cleared it out. Turning on the debug level needs this line on an arduino IDE

Serial.setDebugOutput(true);

and enabling in the menu tools of the Arduino IDE

from arduino-audio-tools.

I don't think it's the gap. I checked it.

I'm not getting any wiser on that. Please check my code again if you can find anything. It is complety diferent in build up than the audio kid. I think something is still active and therefore crashes on this line 276

    if (esp_bluedroid_init() != ESP_OK) {
        ESP_LOGE(BT_AV_TAG,"Failed to initialize bluedroid");

Are you sure that 128920 is enough for bluetooth ?

from arduino-audio-tools.

You where right. I cann't increase the stack size for my task more than 10000. But still crashing after connecting to my phone.

Try to set it to 8192 - increasing the stack size is reducing the available heap

from arduino-audio-tools.

I am connected now. I had to end the i2s like you sad before.

  player.end();
  i2s.end();
  a2dp_sink.start("BluetoothSpreaker");

Now I'm going to test if it works to play music...

from arduino-audio-tools.

Yes it works.

Now I need to get a seprate stack size for the A2DP and for the player. So if a button is pressed I need to delete the task and start a new one I think. It definitely sounds right. :-)

from arduino-audio-tools.

If I delete the task the memory is still in use. I was affraid for this. because I had that same issue before when I runned my code.

For example the std is clearing memory by his self. This was the correction I made...

char* subString(char* s, int index, int n) {
	std::string Str = std::string(s);
	std::string sub2 = Str.substr(index, n - index);

	//https://www.techiedelight.com/convert-std-string-char-cpp/
	std::vector<char> chars(sub2.begin(), sub2.end());
	chars.push_back('\0');

	char* c = &chars[0];
	return c;

	//Serial.println("sub2");
	//Serial.println(sub2.c_str());
	//char* c = const_cast<char*>(sub2.c_str());
	//char* c = strcpy(new char[sub2.length() + 1], sub2.c_str());
	//const char* c = sub2.c_str();
	//Serial.println("c");
	//Serial.println(c);
	//return c;//.c_str();
	//return sub2.c_str();
	// 
	////char* res = new char[n + 1];
	//char res[n + 1];
	////sprintf(res, "%.*s", n, s + index);
	////sprintf(res, "%.*s", n, s + index);
	//memcpy(res, &s[n], n-index);
	//res[n - index] = '\0';
	////Serial.println(res);
	////delete[] res;
	//return res;
}

For example sprintf is ussing a lot of memory and is hard to clear it. You use that in your code a lot I saw that before.

from arduino-audio-tools.

Releasing a2dp memory is a little bit a mess - if you call end(true) it will release - but you can't restart it again.
The only reliable way is - not to release - or to restart the processor.

The only reliable way is - not to release - or to restart the processor.

I need that memory and I need to switch over and over again, so not release it is not an option. Soo the only thing I could do is restart the processor. I think I can do that with my current setup. Please take a look at what I sad and try to use std. I know it's not always possible but I saved a lot of memory with me. Other bluetooth libraries use that to because of that reason.

from arduino-audio-tools.

IDF 1.0.6 in commen is using sprintf for sure and I cann't find where they clear it out. Take a search in the entire solution, you will see. What I mean is that I saw it in the str.h file with things like sprintf and strcmp/strcpy.

from arduino-audio-tools.

sprintf does not allocate any memory and my str.h library does not allocate any memory as well. It is just copying and formatting data which has been allocated by the user before!

By the way your local std::string might be the cause of your stack problems. If you use it with new you can put it on the heap...

from arduino-audio-tools.

I have tested this

char* subString(char* s, int index, int n) { std::string Str = std::string(s); std::string sub2 = Str.substr(index, n - index); //https://www.techiedelight.com/convert-std-string-char-cpp/ std::vector chars(sub2.begin(), sub2.end()); chars.push_back('\0'); char* c = &chars[0]; return c;
}
And it doesn't use memory at all after deleting the task. Do some test with a task and try to delete the task and then check the PortGetFreeHeapSize.

from arduino-audio-tools.

That's right - but you need to reserve stack memory from the heap which will not be available for other use (if you use this as local memory). If this is good or bad really depends on how much memory you have to spare...

from arduino-audio-tools.

That's also right. But I don't want that for my application. What I want is use as less memory after deleting a task. And if I still could start it, is it a plus.

from arduino-audio-tools.

Yep, it's working. I test it with ESP.restart and now I have my memory back.
