using fragmentation

mntdr

Hello, everyone.

I am trying to send a 120-byte message to my coordinator.

At first, I only set the flags: dstEpInfo.txOptions |= (APS_TX_OPT_ACK_TX | APS_TX_OPT_FRAG_PERMITTED); but the transmission still failed.

I finally got it working, but only after I changed my APS_MAX_WINDOW_SIZE setting to 2+.

Does anyone know why modifying the window size was the magic fix for this? I want to make sure I understand the underlying APS logic so I don't run into memory or routing issues down the road.
