[MC13192]: beginner user - LQI?!?

[Flavio82]

Hello everybody,

for a number of reasons i need to conduct a received power measurement campaign using two 13192-EVB boards communicating with each other. I read about the Link Quality estimation capability on the documentation and i was wondering if this is in some way correlated to the RF power at the receiver (perhaps the average received power over a single packet). I found nothing about that in the documentation. In case they are related, what is the relation between them? Is it linear?

In other words, how can i translate an integer ranging from 0 to 255 into a dBm value?

I really appreciate yor help!

Hi,

   You need to check out Section 6.3.5.3 of the MC13192 Reference Manual, Rev. 1.5, for the answer to your question. 

The format for the LQI is the same as CCA:

Signal strength in dBm = - (dec (cca_final[7:0] / 2))

    Thanks,
