Hello, I’m creating a network ox xbee S2Cs in API mode (arduino + xbee as receiver and sensors + xbee as sender). But when I use Arduino I can’t get any data from the router, the serial monitor is blank. I’m trying to check frames log on XCTU and i got this : 11-16-2021 23:48:42.700,-,API2,“COORDINATOR,0013A20041C37D8B,ZIGBEE TH Reg,4061,COM3 - 9600/8/N/1/N,0,46” 11-16-2021 23:44:57.591,0,SENT,7E001611090013A20041C37D8BFFFE00000032000000000900EC 11-16-2021 23:44:57.763,1,RECV,7E0062910013A20041C37D8B000000008032000001090050000FCB2100CB210000030000000003000000000300000000030000000003000000000300000000030000000003000000000300000000030000000003000000000300000000030000000003000090 11-16-2021 23:44:57.763,2,SENT,7E001611090013A20041C37D8BFFFE0000003200000000090FDD 11-16-2021 23:44:57.794,3,RECV,7E00078B09000000230048 It’s say Explicit Addressing Command Frame, Explicit RX Indicator, and transmit status. What’s that mean? Thanks for any help. ---

Most Arduino code uses API mode 1. The Explicit frames include additional data such as the ZDO (Zigbee Device Objects).
