ESP32 Webradio

[Quanghoster]

Hi,
I've just came across your project and am looking at using it in in a project to update an old 80s boombox. This will be the first project using the SDK as I've been using the Arduino IDE so far so a spot of learning to do, though I'm familiar with C and similar tool chains from my Linux programming days.

Cool project, thanks for sharing. One question I have (though I'm sure there will be more) is, is the Bluetooth mode and webradio mode build specific? i.e. when you load the application can you switch between modes at runtime or is the application build just as one or the other?

Thanks,
Andy

The problem is that Bluetooth consumes a lot of RAM, and the web radio needs a lot of it, especially for AAC. It is currently not possible to dynamically allocate and de-allocate the Bluetooth memory, which makes switching between the two modes during runtime impossible. You might get around this if you use a module with external PSRAM.

Hi

I have tried this recently. I mean to use bluetooth with this project and indeed I could not flash the chip because project was to big (I mean flashing was ok, but esp does not boot).
However, I have seen somewhere that new esp-idf (I'm not sure which version) will have or already has bluetooth memory allocated dynamically. Correct me if I'm wrong.

Best Regards
Marek

OK. I get the memory issue. However, could a workaround be that when an io pin used to change from one mode t the other the esp is forced to reboot? The selected mode could be stored in nvram and checked on boot as to which mode is required?

[BuddyCasino]

Maybe, it might be possible to allocate or deallocate BT memory once, I'm not sure. You'll have to test it.

Setting up the environment atm and I'll look into it. I also happen to have an m5stack core so will take a look at working with that. I look forward to contributing as I get up to speed

Hi MrBuddy,
i wrote a icy-meta-parser for this projekt and like to share it.
Only little changes in http-fifo-files with example in app_main.c for Monitoring.
Please contact me ritaripp@gmx.de to send files.

kodera2t/ESP32_OLED_webradio seems not to be interested.

regards

Can you make a pull request on Github?

I'm having some trouble building the webradio... it seems to get itself in a boot loop.

Rebooting...

ESP32_MP3_Player branch master, git commit 91e2f15, submodules updated
esp-idf git commit branch release/v3.0, commit daf1d055, submodules updated

(aside: is there any need to update the submdoules to a specific checkout when checking out a branch? If so, how?)

I've got BT support on, but I get the same CPU hang with BT support turned off. This is my BT config:

Code: Select all

 --- Bluedroid Enable
       The cpu core which Bluedroid run (Core 0 (PRO CPU))  --->
 (3072) Bluetooth event (callback to application) task stack size (NEW)
 [ ]   Bluedroid memory debug (NEW)
 [*]   Classic Bluetooth
 (2048)  A2DP sink (audio stream decoding) task stack size (NEW)
 [*]   Include GATT server module(GATTS) (NEW)
 [*]   Include GATT client module(GATTC) (NEW)
 [*]   Include BLE security module(SMP) (NEW)
 [ ]   Close the bluedroid bt stack log print (NEW)
 (4)   BT/BLE MAX ACL CONNECTIONS(1~7) (NEW)

What can I do to resolve this?

Here viewtopic.php?t=1026&start=80#p7783 i have read something about #define DAC_BUG_WORKAROUND but i can't find it.

I am new on esp32. it would be very nice if someone can help me.
thank you.
