Question: What is deep sleep and what are the conditions for that to happen?
Answer: It is a hibernating state in which the node stops all processes except the battery charging process. It can be caused basically by battery lower voltage (BV<2.7 VDC)
Question: What kind of impact can it have on the system?
Answer: Readings will not be updated on the platform.
Question: How do I wake up a node that went into deep sleep.
Answer: This will require a node reset. First, you put the jumper back on for about 5 seconds and then remove it. Then verify that the node starts with a blue and red flashing sequence ending in a red flashing sequence (flashing red 3 times every 55 seconds).
Next, proceed to map the cable node right away.
