Hi 360customs,
Do you have pcb schematics of this circuit?
If you do can you give them to me?
Thanks.
Hi,
thanks a lot for this Info! 🙂
Do you also have this problem with a very loud “welcome-beep-tone” if you powering it on?
Therefore a “hack” (e.g. deactivating) would be awesome
This can be changed within the configuration keys. You’ll need an SPI-USB programmer to do so, they’re available on i.e. Aliepxress (3rd party).
Do you have a copy of the PSkeys of this device? For some reason mine does’t open anymore.
I tried installing the PSkeys of another speaker and now it opens, but it doesn’t work properly.
Check your mail.
