So once in a while a fez spider with 4.1.8.0. with app deployed boots with a white screen. It doesn’t always happen on the same one, but it occurs on different spiders (we have approx. 150 fez spiders out in the field). After a couple of resets or switch the power off solves the problem and it starts the deployed application.
I can’t imagine this is normal behavior on 4.1.8.0.
All the spiders are powered by a external power source 12v / 1 amp.
This is normal. Spider display configurations persist but they only change when you add or remove the display in the designer. And they only take effect after the second boot.
I assume they have a static known application deployed out there and it hasn’t changed of late, and this is just a behaviour you see at random times after many successful restarts, you get this one bad restart?
I don’t think it has to do with bad cables because the spiders are new and I’ve replaced them to be sure. It happens randomly and on different spiders.
I want to, but till today IFU isn’t available on 4.2. The moment IFU is available I’ll switch to 4.2
btw: we use the spiders for a RFID based reader (Terminal) And we are currently rolling out our project to 60 different locations (mostly museums) within the Metropolitan Area of Amsterdam in the netherlands.
