I am sending Explicit Transmit API frame (0x11) frames using XCTU and the frame generator tool within it while my device is in API=2 mode. I am not getting any confirmation that the packets are being sent and when I sniff the network, there are no packets over the air.
Instead, over the air I see that my device is spamming the coordinator with data requests (63 88 D4 89 17 00 00 A2 B0 04 FF FF)
What are the conditions for (0x11) frame to be sent? Why am I getting absolutely no response? Note, I made sure to send to UART once every second so I'm still in API mode, and other commands (AT commands) give me responses.
