Hi,
Thank you for your answer.
I found this command in CC2420ControlM:
command result_t CC2420Control.setShortAddress(uint16_t addr) {
addr = toLSB16(addr);
return call HPLChipconRAM.write(CC2420_RAM_SHORTADR, 2,
(uint8_t*)&addr);
}
And one call to CC2420Control.setShortAddress(TOS_LOCAL_ADDRESS) in task
PostOscillatorOn() definition, in the same file.
My question is , do I have anything more into account?
What I would have to do would be to wire my MyApplication.CC2420Control with
CC2420ControlM component, and then, whenever I want, call to
setShortAddress(NEW_ADDRESS) with the new address, and as this information
is saved in RAM memory (what I suppose by looking the HPLChipconRAM file),
the mote would change the AM Address till the next time I call
setShortAddress.Could this create any incompatibility with lower components
or make install.<addr> command?Would I have to update this address in
another place?
By the way, I found TOS_LOCAL_ADDRESS in tos/system/tos.h file as :
uint16_t TOS_LOCAL_ADDRESS = 1; where is TOS_LOCAL_ADDRESS defined in order
to be used in other components?
I did not find any #define command for TOS_LOCAL_ADDRESS in tos.h file.
What happens if I have two nodes with the same Address in the same system?
My Base Station will send both of them the same message, or they will have
some problem?
Thank you in advance

Since you're using a CC2420 radio, look at the CC2420Config interface
from the CC2420ControlC component.
