    Link works for me without problems. I am with BT. Interesting, albeit niche, site and Forum:

    "This site is all about the cheap Chinese-ES Sabre Boards + a lot of information about the Raspberry Pi, the Pi itself, Pi-Audio-Distros and so on..

    Also a lot of informations about USB-Bridges like XMOS-XU208, Anamero Combo Bridges and so on..

    Its all about to get the best Hi-Fi out of a Raspberry Pi respective these Chinese ES Sabre-Boards !!"

    To me it looks like a perfect board to implement a high quality player with some extra features, like hardware volume control, filters and extra inputs.
    When it's correct what they say in the description it also seems to have a high quality integrated power source which can run from 15V or 5V and should improve sound quality.

    Also this guy is quite excited about these boards:

    Although he recommends the green version which runs from 15V.
    Keep us posted on your progress. IMHO in high end DACs a lot hinges on the power supply.
    I feed the I2S signal from a squeezelite-esp32 into a Topping D10 (old ES9018K2M version) and am quite impressed with the results.

    I'm curious how you do this, as the D10 has USB input (I think).

    Thanks, Mike

    Brute force.

    The I2s traces from the XMOS to the ES9018 have SMD resistors.
    I removed those and connected the respective GPIOs (via 47 Ohms resistors).
    Same with the I2C lines.

    If you have serial logs, then you should be able to watch the ESP32 as it finds visible devices and possibly attempt to connect to them.
    Been a while but I'm finally having a go at debugging again

    Using firmware
    - squeezelite-esp32-master-cmake-I2S-4MFlash-16-V0.665.bin

    Hardware is an ESP32-CAM i happen to have spare and I've enabled serial and telnet debugging.

    My logs are full of
    [CODE]
    23:14:41.260 -> I (276498) RCCT: AVRC conn_state evt: state 0, [00:00:00:00:00:00]

    23:15:13.873 -> I (309108) bt_app_source: Discovery started.
    {/CODE]

    The only device that appears to show up is my laptop. I've tried 2 bluetooth speakers and my phone. Phone can see the esp32 bluetooth, but not the other way around.

    The Bluetooth Audio device drop down menu is empty and I can't manually enter any values.

    Any other ideas?

    I'm wondering if my issue might be the Ai-Thinker esp32-cam is based on the ESP-32S which is WROOM rather than WROVER based.

    What is the restriction that means we can't use WROOM based modules?

    • ESP32-WROOM-32 - 4MB Flash and 4MB PSRAM
    • ESP32-WROVER - 4MB Flash and 8MB PSRAM

    As I said in the first post of this thread, the WROOM *cannot* work as you need 4MB of PSRAM. The WROVER does *not* include PSRAM, only an extra 4MB of Flash. Make sure that the ESP32-CAM has PSRAM (which seems to be, external to the AI-Tinker module which is *not* a WROOM) but confirm that with the boot message. Try to us eLMS first rather than BT.
