How to read L/T from the Wall Router, by API command?

Python
1

Hi guys,

I’ve rad the thread on: http://www.digi.com/support/forum/viewthread_thread,86#279

which very nicely explains the frame to be sent to the Xbee L/H/T sensor, to read those 3 values from the sensor.

I tried to apply analoge frame structure for reading the L/T from the wall router, bu tno success…

Ok…the frame for reading the Xbee sensor L/H/T works…I get all the 3 values in the response.

But when I try to read a Wall Router (it has only Temp and Light sensor), I’m sending the frame that looks like:

0x7e
0x00
0x0f
0x17
0x01
0x00
0x13
0xa2
0x00
0x40
0x2d
0x02
0x05
0xff
0xfe
0x02
0x49
0x53
0x23

and I get the response:

0x7e
0x00
0x0f
0x97
0x01
0x00
0x13
0xa2
0x00
0x40
0x2d
0x02
0x05
0xff
0xfe
0x49
0x53
0x04
0xa1

…so, in the response, after 0x49 0x53 (“IS”), there’s the 0x04 byte…what does it mean? I’ve got no values back from the Wall Router?

Any ideas where am I wrong?

Thanks,

Vlada

Oh, I got it…my mistake…somehow, the node I was trying to read wasn’t joined to the network…
