EasyBee demo application
Posted: Mon May 18, 2009 1:34 pm
Hi to all,
I\'m working on the EasyBee demo application found in this site. I\'m interested to read the value of the RSSI register of the EasyBee tranceiver, so I used the function cc2420_rssi_get() of the demo code. The problem is that I always get values from -99dB and -100dB, even if the radios are either near or far... To obtain the right value I had to make the two\'s complement of the value read from the cc2420 register, as written at page 49 of the CC2420 manual, before adding the RSSI_OFFSET of -45 dB. Does someone know why the RSSI value doesn\'t change??
Thanks,
Alberto
