Estimote stickers dropping like flies :-(

[T_X]

As promised, here are the pictures of the broken sticker we opened:

As you can see, the big soldering blob for the battery socket has an ugly cut next to it.

For the battery life, I’m currently trying to investigate whether it might be due to how node-bleacon scans (or whether it is a sticker firmware or hardware issue):

Passive vs. Active Bluetooth LE Scanning

Hi! Are there any implications on battery life for Estimote stickers regarding these two scanning modes? For instance, might active scans prevent the stickers to go into some sleep or something similar? Could a continuous “hcitool lescan” reduce the battery life of an estimote sticker? I think noble / node-bleacon uses some active scans, too. And I’m wondering wether that could create the very short life time of stickers we are experiencing here. PS: Here are two places where noble sets some …
