Posted at 2020-03-21 by @MaBecker Well, the beep is very quite, move close to your ear and try again. |

Posted at 2020-03-21 by nsg Hi, thanks for the quick reply. I just put it right next to my ear and hear nothing. It could be my hearing I suppose! It does return promise in the IDE so the command is working, just no sound. |

Posted at 2020-03-21 by @gfwilliams The beep is quiet, but this could be a problem with your watch. I've already had one case where it seems the factory's testing and quality control didn't seem to extend to checking that a speaker was even installed :/ |

Posted at 2020-03-21 by @gfwilliams If you're willing you could open the back and it'll be really obvious if there isn't a gold disk on the back of the battery. If that's the case we can either swap it or I can send you a piezo to solder on |

Posted at 2020-03-21 by nsg Well blow me, you were right! I'll have a root around and see if I have a piezo disc, but if not would appreciate you sending me one. Thanks, NickAttachments: |

Posted at 2020-03-21 by idf Hi, I have the same problem as nsg. I have two Bangle.js watches (The Both hands pledge) and neither of them has the beep() making any sound. I have removed the back from one of the Watches and there is no piezo visible and no wires soldered to the pads shown in your photo above - just the battery below the circuit board. I have some piezos with a diameter of 2 cm that look around the right size. Should any piezo that fits be ok? Or should I wait for you to ship me some? Would they need to be stuck to the battery or insulated from the board or anything? Ian |

Posted at 2020-03-21 by ThomasVikström Same here, no beeps. |

Posted at 2020-03-21 by Gefrierbrand Same here, no beeps. I will open it later to check for the piezo. |

Posted at 2020-03-21 by Old_account Oh blimey... Starting to look like they missed the piezo on all watches. |

Posted at 2020-03-21 by lindenaar I didn't open them yet but the two I received today (which look great through!) don't make any sound when trying the sample apps either :-( |

Posted at 2020-03-21 by Robin Sat 2020.03.21 Thank Goodness, missing part. I was beginning to think that this (death - no sound) was a result of an infection caused by the current Pandemic. ;-) . . . and, . . . after @gfwilliams put in all the extra effort Bravo to get these out on time, we now have a potential factory recall mess on our hands! Maybe the factory will kick in a major monetary offset, and give either Gordon etal or the user the opportunity to perform the repair surgery? anyone speak Mandarin? |

Posted at 2020-03-21 by nsg I am happy to do my own surgery rather than send it back. |

Posted at 2020-03-21 by Robin Your enthusiasm @nsg is welcome, and I can see the benefit of not dealing with return shipping and delays etc. Too tiny for my now non-dexterous fingers and fading eyesight. But, consider the scope of this. At least five (posted above) out of say one hundred shipped is five percent failed assemblies that were passed off as good by the assembly house. 5% !! Several hundred are shipped, and the balance remaining most likely boxed. Lot's of effort unboxing, programming, reboxing, labeling, box boxing, trip to the P.O. to ship.
And now we are faced with, unboxing, repowering, load a test app, test, make a decision to ship to the potential unhappy purchaser, box, . . . Wash, Lather, Rinse, Repeat, . . . off to the P.O. Gordon's efforts would be better served, coding and creating the next Bangle Pro/Deluxe than having to now deal with many days to test out the remaining balance to ship for the K.S. campaign. IMO back to the manufacturer and have them apply the fix as it was paid for in the purchase bargain. (even with yet another eight week delay) Personally, I'm tired of the untested crap (even with improvements over the years) that does make it to market that is shipped from that side of the world, as I spend an unbelievable and unnecessary amout of time just in the return shipping process. Capitialism beware, this is what can happen when seeking non- Capitalist low cost, low pride in workmanship alternatives . . . . > EDIT: second thought, a factory offer of a piezo element and an additional free Bangle along with a rebate of half the value of the K.S. pledge might come close as an offset. *Just a thought . . . .* my 0.02 worth |

Posted at 2020-03-21 by Tx Hm. I think a missing beep is not that issue (at least for me). A missing buzzer would be more an issue. |

Posted at 2020-04-05 by nsg The beep from the vibration motor is extremely quiet to my ears. I had to hold it close to my ear to hear it at all. |

Posted at 2020-04-06 by @gfwilliams @user110973 that piezo looks fine to me! If you have a choice of voltage/impedance I'd choose the lowest voltage or lowest impedance as they'll be the loudest, but otherwise any should work. @nsg yes, it's not great, however even when the piezo is installed it's not desperately good. Personally I'd say the vibration motor is maybe half as loud as the piezo - so it' not masses! |

Posted at 2020-04-06 by user110973 @gfwilliams Another one has an impedance of 1500 Ohm: https://cdn-reichelt.de/documents/datenblatt/B400/EKULIT-190023.pdf Would that be even better? |

Posted at 2020-04-06 by Raik Considering they all cost about 40 cents each, why don't you order one of each, "plug" them in to test and then choose the loudest? |

Posted at 2020-04-06 by @gfwilliams Sorry - my fault, I was in a bit of a rush. I updated the post, but I meant lowest impedance or voltage. But I'm afraid I'm struggling a bit to keep up with all the questions and code contributions so I haven't had time to vet any Piezos in particular... But if anyone found any good ones (especially from German distributors because there have been are many Bangles in Germany!) then I'd be very happy to add links to them somewhere prominent! |

Posted at 2020-04-07 by user110973 I ordered three types and I'll write about the results. |

Posted at 2020-04-07 by msdeibel Same here with the missing piezzo. Really a shame. @user110973 which ones (from Reichelt?) did you order? I order some of the others then for some more testing. |

Posted at 2020-04-12 by user111277 Hello all, just got my Banglejs and no beep, though the code does return the promise. Buzz works fine. I still need to take it apart and confirm missing piezzo. I may have one from a radio shack experimenter parts kit. Otherwise watch seems fine. Like the Mario clock. ;) Thanks |

Posted at 2020-04-13 by msdeibel @user110973 I just double checked and these are really the only ones that make sense. I overlooked that the other ones I had found with the filters are "feedback" piezos. |

Posted at 2020-05-05 by kat just joining the party! my bangle also lacked the piezo, and I just fitted it with a EPZ20MS64W since that was easy to order. not very loud, but working :-) Thanks, Gordon, for this little gadget (or toy?), I am now also entering the world of javascript. Even with the recent obstacles this is a fun project to support! Stefan |

Posted at 2020-05-05 by kat What about the larger (EPZ27) models with lower impedance, any experiences yet? |

Posted at 2020-05-17 by 7oo1er Hello! I took "10 Pcs Piezoelectric Piezo Ceramic Wafer Plate Dia 20mm For Buzzer Loudspeaker" from Ali. Put it inside, closed.. So weak, hardly hear in 5 cm from ear. Buzzer sounds better! Took Pico, connected with other piezo. And every one from that bunch is very weak.

Sounds that your fix is like the original piezo. You can't barely hear it too. You don't miss anything with your solution compared to the original piezo. From my point of view it's not worth to fix a missing one. Just use the buzzer in your apps. |

Bangle.buzz(); works just fine in the IDE but I hear nothing with Bangle.beep();
I have upgraded the bootloader.
