 03 Jan 2008 15:34 Wireless Sensor Network, TinyOS, and Micaz platform question |
|
|
|
Hi,
I am using the Crossbow Micaz motes in a Wireless Sensor Network project. My mote uses CC2420 as its transceiver.
I was wondering if it is possible to change the transmission frequency (channel) at runtime? i.e. while the program is running.
I know how to do this using the parameter DCC2420_DEF_CHANNEL in the Makefile...however, I am willing to know if this can also be done on the fly.
Thanks a whole lot in advance.

hi zeeshanzia84 ,
You can change the frequency of operation by changing the content of FSCTRL register. refer datasheet of CC2420 Pg.50 on how to change the frequency of operation. Please be minfull of local RF regulations.
With Regards

I believe there is also a command in the TinyOS to do that while it is running.
This is the command definition:
| Code: |
| command result_t TunePreset(uint8_t freq); |
Its part of the RadioControl interface.
Hope it helps...
