I'm trying to know the address of all nodes in my networks (for now there are only two nodes, concentrator, and router, but I wanna make it simple before going deep). I created my network with my Concentrator by creating my PANID, assigning a channel and also putting DH 0 and DL 0F. This is the config from my Xbee S2D
Concentrator
CE 1 - OK
ATOP - A8E4F62D42AB6EE1
ATOI - 4AAA
MY ID - 0
Operating Channel - 14
ATAI - 0
DH 0- OK
DL 0F- OK
ATAP 1 - OK
My Router
ATID - 0
ATOP - A8E4F62D42AB6EE1
MY ID - D6F5
ATOI - 4AAA
JV 1 - OK
ATAP 1 - OK
this is my array that I send
byte API_AT[] = {0x7E, 0x00, 0x04, 0x08, 0x01, 0x4E,0x44, 0x64};
but when I read my Serial port, I got nothing.
This is my code from Router
#define OK "OK"
#define ERROR "ERROR"
#define CR '\r'
#define LR '\n'
byte API_AT[] = {0x7E, 0x00, 0x04, 0x08, 0x01, 0x4E,0x44, 0x64};
byte AT_Frame[] = {0x7E, 0x00, 0x04, 0x08, 0x01, 0x4E,0x44, 0x64};

I also tried to send Remote AT Command Request frame (0x17) this is the packet
byte AT_Frame[] = {0x7E, 0x00, 0x0F, 0x17, 0x01, 0x00,0x00, 0x00, 0x00, 0xFF, 0xFF, 0xFF, 0xFE, 0x02, 0x4E, 0x44, 0x58};
but with the same result
I could resolve my problem. When I entered in AT mode, I had to exit before sending any message from my Xbee.
