We consider to use our B5 devices for a 8 km link in the Swiss Alps. The client is a measurement station powered by solar energy only that’s why the wireless link is only active in two cases:
- every hour for a short transmission of the system state
- in case of a flood an alarm is issued and webcam images are transferred over the wireless link
The B5 needs 1:15 minutes for starting up and establishing a connection. This is far too long for us as the time until the flood arrives the valley is only 10 minutes…
Our question: is there any chance to speed up the boot process (<40 seconds would be acceptable) or is there a low power mode we could enter when the wireless link is not needed?
