Sx1276 CAD not stable

LoRa Basics™
#1

Hello there,

I am using sf10,bandwidth 125khz,codingrate 4/5,preamble length 8,symbol timeout 5 in slave sx1276 and slave calls “SX1276StartCad” to be in CAD mode.
A master sx1276 using sf10,bandwidth 125khz,codingrate 4/5,symbol timeout 5 and the master sends one byte data with 100 preamble length. and I also tried 30, 20 200 and even random preamble length in sending.
The result is that slave can be waken up sometimes, but not in other time, it is not that stable.
Where can I improve?

Thanks,

Peter
