Hi All

I'm running a GL865 and it would be useful to know the network registration status by monitoring the status LED. When the module is not registered the status pin is low for around 1 second then high for around 0.5 seconds. When registered the pin is low for around 3 seconds and high for around 0.3 seconds. Any suggestions as to the best way to determine if the pin remains low for say 1.5 seconds. I'm working on the fact that if it is low for that period it must be in a registered state, there's no need to time to 3 seconds so long as the period exceeds the unregistered value.
Cheers Pete
