Can the BLE audio examples run on an ESP32-C3 or be built for native_posix?

[twaclaw]

Hi there,
I am trying to build and run some BLE audio examples, for instance, west build -b esp32c3_devkitm samples/bluetooth/unicast_audio_server/; however, I get some warnings and Zephyr fails to boot after flashing.

zephyrproject/modules/hal/espressif/components/esp_phy/src/phy_init.c:678:5: warning: implicit declaration of function 'phy_bbpll_en_usb' [-Wimplicit-function-declaration] 678 | phy_bbpll_en_usb(true); | ^~~~~~~~~~~~~~~~

Are there any limitations on this board to running these examples?

I also tried to build for native_posix and pass a device to the executable (in Linux) but I keep getting errors.

sudo systemctl stop bluetooth sudo build/zephyr/zephyr.exe --bt-dev=hci0

*** Booting Zephyr OS build zephyr-v3.2.0-3518-g7b5780e00764 *** [00:00:00.400,000] <inf> bt_hci_core: bt_dev_show_info: Identity: 04:EA:56:3C:6F:67 (public) [00:00:00.400,000] <inf> bt_hci_core: bt_dev_show_info: HCI: version 5.1 (0x0a) revision 0x0100, manufacturer 0x0002 [00:00:00.400,000] <inf> bt_hci_core: bt_dev_show_info: LMP: version 5.1 (0x0a) subver 0x0100 Bluetooth initialized Failed to set periodic advertising parameters (err -95)

Any guidance is much appreciated.

Thanks in advance.

Hi @twaclaw, I faced same warning here ( warning: implicit declaration of function 'phy_bbpll_en_usb') but apparently this is not a real problem. I wrote a line: extern void phy_bbpll_en_usb(bool en); on the top of phy_init.c file and warning was gone.

For me, no one of BLE neither WIFI examples run on esp32c3. Application hangs on line: register_chipv7_phy(init_data, cal_data, PHY_RF_CAL_FULL); of this phy_init.c file.

When you did run audio example on native_posix, this "Fail on advertising" is not relate to problem that happen to esp32c3.

Thanks a lot for the answer @icatorze.
That's unfortunate that the examples don't work on the esp32c3.
The native_posix messages are unrelated.
Best,
