I got two 5-packs of PocketLabs and am running the What is Temperature? Lab in which the PocketLabs get submerged in water inside sealed plastic bags. All of the PocketLabs paired well initially, but then a couple of them began coming unpaired and wouldn't repair and the LED wouldn't turn on.
When I opened up the back of them there was condensation inside. I absorbed as much liquid as I could, popped out the battery and dried it and its contacts. But when I inserted the battery back in the LED wouldn't turn on, except briefly when held in a particular position by a screwdriver. I've been unable to get two of my ten PocketLabs to pair again for this reason and a third because the box with the on/off button on it came detached from the board.
Any suggestions on the pairing issues and on how to reattach the button? Thanks!
