The standard 128 samples were not enough.
With "data samples 2000" it worked (got the UID with the CRC).
Or even better, upload it somewhere :
"data save name.pm3" (it will be saved in your /pm3/client/ folder)
data plot
hf 15 read
data samples
data norm
hf 15 demod
The graph is shown but I do not get any result from "hf 15 demod"
