New receive option?

Hi all,

I have used an end device to send a Zigbee Transmit Request Package to a coordinator:

7E 00 11 10 01 00 00 00 00 00 00 00 00 FF FE 00 00 00 00 00 F1

Then what I have received on the coordinator side is :

7E 00 0F 90 00 13 A2 00 40 5D 3B A7 F2 8C 41 00 00 00 7C

What is strange is that the receive option 0x41, I looked in the datasheet of the ZB module (90000976_F) and there are only the following options:

0x01 - Packet Acknowledged
0x02 - Packet was a broadcast packet
0x20 - Packet encrypted with APS encryption
0x40 - Packet was sent from an end device (if known)

So can anyone tell me what does it mean the value 0x41? Thanks!

With options bytes, if more than one option applies then they’re added together. So 41 is saying that the packet is acknowledged (0x01) and was sent from an end device (0x40).
