I use two XBEE S2C (XB24CAUIT-001) in API mode to transmit data from one module to the other. I can correctly send and receive each frames but I sometimes observe that a frame is received twice.
For example: I want to transmit "ABC" and then "DEF". The frame "ABC" is received at 12:00:000 and I receive it again at 12:00:001 despite I am waiting for "DEF".
I would expect the frame ID management to reject this as it should detect that we already received "ABC" the first time and sent an ACK paquet. Moreover, these two frames are always received 1ms or less apart even if I specified a 500ms delay between two frames which is very strange.
I think that there is a problem of frame ID management following the loss of the ACK paquet. Is there an option I should consider in XCTU to resolve that ?
