Hi guys, looks like we isolated the problem. 

Using two nodes about 3m apart, one sender, one receiver, one message every 
1.5s on average we get the following delivery ratios:

DC        mean    90% confidence interval
5%        0.097   0.086   0.11
10%      0.21     0.126   0.295
20%      0.26     0.18   0.34
50%      0.55     0.46   0.63
100%    0.995   0.98    1.00

Once we switch on LPL, the packets are hardly detected by the receiver.

Best, Andreas
