I'm planning a system where a number of r-pis run headless, and totally unattended for extended periods (several months). I shall be controlling them via the internet over a wireless link.
So far, so good. I am noticing that if I power cycle such a pi while running, on occasions, it doesn't correctly reboot (at least the wireless network isn't established correctly), and I have to perform a hard reset by shorting the reset pins on the pi.
Obviously this is unacceptable for my system (the power is prone to interruption). Does anyone here know how to circumvent the problem, short of running it off a UPS?
Failing that, there was a guy on this group not so long ago previewing a ups he was developing for the market; did that ever happen?
cheers, Tony
