Hi Christian, I have successfully changed the CCA check rate on my motes, but sadly is does not have any effect on my Packet loss rates. I tried values between 1U to 50L an proofed it with an Oscilloscope. I also tried to switch RF230_HARDWARE_ACK on but the result stays the same. Do have another idea how to fix that problem?
