  @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 @Gordon said, maybe it is stuck randomly in Serial mode. wish the self-test would have more info/tests 😋

  no battery leakage signs. also it was stored in another plastic case with no damage signs whatsoever.

  any tips on how to debug the problem ? I dont want to have a puck brick :/

  I have nothing wired to any of the Pucks.

  PuckJS FC05

  • still slow first time today.
    
  • hard reset -> speedy. works great for now. 😋
    LATER EDIT - after 10 minutes, reconnect via webIDE, slow again. hard reset. speedy again.
    
    

  PuckJS CB34

  • drained a new battery to 2.26V
    
  • put a new battery. hard reset. still no connection 🤯
    
  • self-test - blink green.
    
  • weird as the MDBT has some discolouration on the shield (battery leak?) - it was in the silicone case all the time

  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)
