Hi,
thank you for your advise. I tried to build the mica2 target, but I didn't
succeed.
It seems that the CC1000 is not ready for the new LPL implementation. There is
no command "setLocalWakeupInterval" in the CC1000 LPL interface.
Should LPL work with CTP with my changes described below?
Sorry I made a wrong description of the failure in my last email.
I try to simulate CTP with LPL in Avrora and it seems that the packets are
sent with lpl behavior (so they have a long preamble), but no packets are
received. (But the applications "TestLpl" and "MViz" are working fine with the
same configuration)
Best Regards
Richard Figura
