Hi,
unfortunately I do not get ahead and I need your assistance. I can establish a 802.15.4 connection between Coordinator (CO) and End-Device (ED). The datatransfer from ED--> CO is working well. As a response of this data frame I would like immediately send back a data telegram from CO--> ED.
The problem is the ED does never receive the paket. Why not?
If I run the communication with beacons and in indirect mode, it works.
Attached you can see the daintree trace of the establishment of the communication and the first data transfer from ED-->CO. Why does the communication from CO-->ED not work?

Any ideas?

Thanks for any help
