I'm using XBee series 2, hardware version: XB24-BPIT-004 revB, software version: XB24-B, ZNET 2.5 COORDINATOR AT 1047; XB24-B, ZNET 2.5 ROUTER/END DEVICE AT 1247.
I encountered the following problem: after sending ATDN command to XBee (it returns OK and according to documentation should immediately switch into communication mode) I try to send a message to the node but part of the first message or the whole first message is always lost. The second message and following messages are sent without problems. I tried using delays after ATDN command but it didn't help, the information is lost. Also tried changing the baud rate, didn't help either.
I'm not using sleep mode at router/end devices for sure (SM=0).
Could you kindly help to figure out the solution to this problem?
