ANNOUNCE: Squeezelite-ESP32 (dedicated thread)

[RPlanto]

That will work.

Remember though that you need an esp32 module with at least 4Mb of PSRAM. The appropriate module is a WROVER and definitely not the WROOM that the a2dp sink is using

working! thanks again!!



I have a question regarding the configuration. I see this, but i have no idea what it means:

"autoexec1" squeezelite -b 500:2000 -d all=info -C 30 -W -o SPDIF -Z 192000 -n "squeezelite-fb7b64"

the use i want to give to the streamer is to stream from my LMS where i have a HDD with all my CDs ripped (that is, everything 16 bit 44kHz) and a few FLACS and mp3 that i doubt are anything higher than 44kHz. I value a lot that the streamer is as stable as possible. Would you suggest that i change something in the line above? for instance i see it has the max sample rate set at 192 kHz, best if i lower it to 44? thanks for any suggestions!

Anybody knows if TTGO T-Koala with WROVER-B is working?

If you get the ESP32-WROVER-B version I see no reason why that wouldn't work.

From the Readme...

"In 16 bits mode, although 192 kHz is reported as max rate, it's highly recommended to limit reported sampling rate to 96k (-Z 96000)."

This setting does nothing unless you play files over 96000.

SPDIF, with the trick I've used will work fine at 48kHz and sometimes can work at 96kHz, but not at 192, for sure

Wrover is not = Wrover ...

I bought T8 1.1 in the past. But I was then taught that the S2, although it has the newer in more powerful LX7 core, should not be sufficient for Squeezelite.
So this time I rather ask in advance if the Wrover-B really works. 😉

I have a couple of different boards with the WROVER-B chip. They all work perfectly.

thanks for your answers guys.
As i understand it (but i am not sure), the setting in that line is a maximum, and in any case the music in my server is 44.1kHz/16bit, so i have done what mboxler suggested and lower the figure after -Z.
Any other comment about the rest of the line? anything else that i could or should change? thanks a lot!

Thanks 👍🏼

Do you also see a chance to use an S2? Possibly. If you make restrictions via settings?

The chip needs at a minimum 4mb of flash and 4mb of PSRAM, which the WROVER has. The maximum you can get with an S2 (ESP32-S2FN4R2) is 4mb of flash and 2mb of PSRAM. Looks like an ESP32-S2 doesn't have any flash or PSRAM.

Are you sure? Think you can add external.

Have this one, bought 2 years ago...

shorturl.at/iLY28

Specifications show 4MB Flash and 8MB PSRAM

Sorry I'm no help. Page 11 of the datasheet states otherwise???

I do see where one can map to external memory, but I don't know how one could do that with Squeezelite-esp32..

I think PSRAM is not the problem, you can connect up to 1GB. But how is the performance of the LX7 single core I'm compared to the LX6 dual core?

What I have read, the performance should be comparable. But the LX7 core is much more power-efficient and especially the WiFi performance is much better. Among other things, antenna diversity is also supported, so even 2 antennas can be used and various extensions of the 802.11n standard.

Or are there other points that speak against using the S2?

[philippe_44]

Just to be clear again: only the regular esp32 is supported. NO OTHER VERSION IS

It's a maximum yes but it means that LMS WILL send unchanged (not resampled) data if the rate is below that one, which is not what you want.
