Packet Transmission

XBee & XBee Gateway XBee - 802.15.4
1

I am using the following hardware/software
XSTICK: XU-Z11 (network coordinator)
XBEE RF Module: XB24CZ7RIS-004 (end device)
XCTU Version 6.3.0

I am trying to send a packet from my end device to my coordinator; so far unsuccessful. I am sending the letter “S” to the UART port of my end device at a baud rate of 9600, 8 bits, 1 stop bit, no parity. API Output Mode (AO) set to Explicit on both devices. API Enable (AP) set to 1 on both devices. I turn on my device and the consoles window begins to display packets coming and going to the coordinator. I’m under the assumption that I am looking for an Explicit RX Indicator packet with a Receive option of “02” indicating that it was a broadcast packet, the 64-bit source address matches my end device, and the RF contains the letter “S”. So far, I’ve only seen packets full of random characters and Receive option of “01”. Is there a major step that I am missing here?

Can you share both Tx and Rx API frames here?

I only get three types of frames: Explicit RX Indicator, Transmit Status, and Explicit Addressing Command Frame. The Explicit RX Indicator seems to vary in length as well.
