Intro
------
The payload of a IEEE 802.15.4 packet is 127 bytes. This implies data may not 
fit in a single packet. As we also want to avoid fragmentation we provide a 
mechanism for sending independent reports. A report can be seen is fixed number
of data readings prefixed with meta information giving the source the data. We 
call this prefix a tag. In summary TAG=VALUE.

Example:  T=24.1   

One report consists of a selection of TAG=VALUES set in firmware. The report 
is sent at a periodic interval also set in firmare. The firmware commands is 
"ri" for report interval and "re" to select the tags. The firmware supports 
four different reports (from firmware 6.0). The different reports are addressed
via  # sign and numberng starts from 0. 

Example:

ri #0 30      
 Sets report interval for report #0 to 30 sec

re #0 auto
  Sets the vars guessed be the firmware
 
re
#0,mask=txt,e64,t,v_mcu,v_in,a3
#1,mask=none
#2,mask=none
#3,mask=none

There are a total for 4 possible reports. We see above only report #0 is set.

ri
#0,interval=30
#1,interval=0
#2,interval=0
#3,interval=0

ri command lists all report intervals.
