I need to send messages to multiple routers (18) in AT mode as fast as possible and reliable.
Broadcast was as dissaster.
Now I try unicast from coordinator to routers with API mode.
This works good as long as all messages with 64bit addresses used in API frames reach their destination.
If one router is offline, or if one 64bit address is not correct all goes wrong, long delays and some messages not reach the online routers anymore.
I disabled the bit in byte 5 to ask for a confirmation, but that seems not to help.
Why this problem is happening?
How can I solve this please?
Thanks in advance,
