Sorry for the delay.
I ordered these:
EPZ-20MS64W Piezoelement, 6,4 kHz, 400 Ohm, bedrahtet
EPZ-15MS60W Piezoelement, 5 kHz, 1500 Ohm, bedrahtet
EPZ-27MS44W Piezoelement, 4,4 kHz, 200 Ohm, bedrahtet
I ordered three types and I'll write about the results.
That would be to easy...
There are so many different types of piezos ( https://www.reichelt.de/signalakustik-c6560.html?GROUPID=6560&GROUPID=6560&&nbc=1;SID=94XoiXrqwQATQAAHctp0w31e14953fa14751d233b694115518b39 )
Another one has an impedance of 1500 Ohm: https://cdn-reichelt.de/documents/datenblatt/B400/EKULIT-190023.pdf Would that be even better?
I would like to buy a piezo ceramic element, but I'm not sure which one to choose. What about this one? https://cdn-reichelt.de/documents/datenblatt/B400/EKULIT-190031.pdf
I made the update of BootLoader and Settings as recommended. The firmware is 2v05. That's the latest, I think.
Both work fine. And surprisingly. Bangle.beep() also works now.
Thanks for your support,
yes, I bought it via the espruino shop.
No, only when I try "Bangle.buzz(); "
"Bangle.beep();" does nothing.
Same to me. I have no piezo. And the rubber wasn't properly installed. Thank god, I haven't tried swimming.
Nevertheless, I paid more than 100 Euro (incl. shipment), so I'm really disappointed. Because I needed the speaker for my app.
Now, I changed the setting of "Beep" to "vibrate" in the settings but nothing changes. Bangle().buzz(); makes it buzz, but with Bangle.beep(); absolutely nothing happens. No buzz and of course no beep.
