Hello,
I am testing a simple setup, fully with the XCTU software no external code, to understand the behaviour of the Transmit Request (API Frame 0x10).
The setup is composed of a Xbee Zigbee PRO S2B coordinator in API=1 mode and a Xbee End Device S2 in API=1 mode.
I have no problems when transmiting data (Transmit request) from de the coordinator to the End Device, whenever i send a Transmit Request i get an immediate Transmit Status from the End Device acknowledging the reception.
But, when i try to do it from the End Device to the Coordinator, it presents a strange behaviour, only after sending a few transmit requests i get the attention of the coordinator and it starts sending the Transmit Status (API frames) acknowledging the reception of the packets.
After receiving the first Transmit Status from the coordinator if i keep on sending data with the End Device i keep on receiving the correct transmit status from the coordinator.
After stopping transmission and waiting 3 seconds (more or less) i get the same behaviour described.
It is like the Coordinator needs time to start handshacking when receiving data from the End Device.
Anyone has any idea of what might the problem be?
What more information can i give to help?
I leave you the config file XML for the Coordinator and End device:
