According to the description of CCA_PERIOD[ ] on page 41 of the ref manual (DocID 022758 Rev 10) , Tcca is the time between two successive CS samplings but the CSMA flow chart on page 40 indicates that CS sampling is done continuously for Tcca duration. I guess the flow chart is wrong. We urgently need to get SPSGRF-868 working for a European customer. Also please confirm that the Tbit is (1 / 34.7 kHz) = 28.818 micro-secs.

Hi,
I've noticed this issue in the data sheet too. I'm pretty sure that the carrier sense sampling is performed contiously during the clear channel assessment period T_CCA. Moreover, T_bit depends on your data rate.
