Posted at 2018-07-13 by @gfwilliams When was the last time you rebooted? Worth a try... Also, are you downloading/uploading anything over WiFi? Often Bluetooth LE and WiFi use the same aerials and so repetitive WiFi traffic seriously impacts Bluetooth LE performance. I remember trying to give a talk while streaming my display over WiFi and it was a complete disaster. The second I moved to a cable everything worked faultlessly. |

Posted at 2018-07-13 by tbd I do a hard reset every time after a firmware upload. no uploads/downloads while testing (checking in Activity Monitor | Network). wonder why I get only a ">erial1" on PuckJS CB34 if I try connecting via BlueFruit iOS app UART) |

Do you have things wired up to your Puck.js? Generally it'd only be saying that (I guess it's trying to transmit If you've got stuff wired up to it (especially if that stuff is producing a changing signal on |

Posted at 2018-07-16 by @gfwilliams That is very strange - any sign of the battery leaking? Is it possible it got wet somehow? The case is pretty water resistant but if it got damp and then left in the case, it'd just be sitting powered up in humid conditions for weeks which would be a disaster. Anyway, I bet that's your problem. Chances are the rest of the contacts are that corroded, which means the UART pin probably got pulled up to 3.3v on boot but is more or less floating - when the UART is on it'll drain the battery very quickly - and even more so if it's receiving random data all the time. |

Posted at 2018-07-16 by @gfwilliams Can you try the long-press on boot thing to clear out saved flash memory? That's usually the issue with Do you have any isopropyl alcohol (isopropanol)? I'd suggest going over the whole Puck.js with that and a toothbrush (obviously with the battery out). It's usually pretty good at cleaning up contacts, and might solve your Serial1 issue. |

Posted at 2018-07-17 by @allObjects ...just had this `P``Unable to retrieve board information``` in a similar setup but connecting to a PICO and trying to flash... It was a malfunctioning / spotty connection... that lead to all kinds of issues... It found the device, but could not properly / continuously communicate and stay connected. Wire connectivity is different from wireless, but in the end in the application layer - from where this message comes - it is the same. Fixing/replacing my cable and making sure it is completely plugged in both sides fixed the issue for me. But as said, I do not know what exactly to suggest for wireless situation... may be checking with BLE from a phone - to at least figure out which side has the issue? |

Posted at 2018-07-17 by tbd @allObjects laptop works fine with another puck (fc05) with v199. the only thing that I tried some time ago (2-3 months) was to make a serial connection. maybe I fried something then ? as @gfwilliams said, maybe it is stuck randomly in Serial mode. wish the self-test would have more info/tests 😋 |

Posted at 2018-07-18 by @gfwilliams The self-test does come up green though? If you did end up connecting a high voltage to However the bad connection may be related to the corrosion. If you search for the device with your laptop (or the Web Bluetooth screen) do you see a high signal strength - or is it quite low compared to the other Puck.js? |

Posted at 2018-07-19 by user73560 Hi @gfwilliams, I upgraded two of my Puck from 1v97 to 1v99, uploaded a code and saved it.
Any ideas ? |

Posted at 2018-07-19 by @gfwilliams Hi - please can you post in a new thread and I'll try and help out there? @TBD's connection problems don't seem related at all other than that he used 1v99? |
