I have a bunch of sleepy devices, I would like them to wake up and send their parent_adress.
I know there's a possibility to send AT command "ND" to recieve this data.
But our trials has proven that this is not that reliable. We don't always recieve the data when the sleeping device wakes up.
Is there a possibility for the sleepy devices to send the parent_address on their own?
Or do you guys have any other advice?
