Sending data from coordinator to end device


I am using an XB24-B coordinator and an end device with the following settings:

coordinator (version 1020)
CH: e
ID: 234
DH: 13a200
DL: 40488ecd
SH: 13a200
sl: 40488ecc

end device (version 1220)
CH: e
ID: 234
DH: 0
DL: 0
SH: 13a200
sl: 40488ecd

It is no problem to send data from the end device to the coordinator,
but the other direction doesn’t work. How can I solve this?

Thanks in advance

try the co-ordinator also in the broad cast mode.

it definietly works
