[closed] Fail Code when Transmitting

[funky81]

Finally, i've success flash my arduino pro mini to run at 1MHz.
But somehow the message never come to gateway and when I debug, it said something like these

sensor started 1, id 1
send: 1-1-0-0 s=255,c=0,t=17,pt=0,l=5,st=fail:1.4.1
send: 1-1-0-0 s=255,c=3,t=6,pt=1,l=1,st=fail:0
send: 1-1-0-0 s=255,c=3,t=11,pt=0,l=21,st=fail:Basic-Sketch-MySensor
send: 1-1-0-0 s=255,c=3,t=12,pt=0,l=3,st=fail:1.0
send: 1-1-0-0 s=255,c=3,t=0,pt=1,l=1,st=fail:100
Startup Finished
send: 1-1-0-0 s=255,c=3,t=0,pt=1,l=1,st=fail:100

What is that fail mean? Please help
btw, I have properly setup my nrf with arduino pro mini (cable, etc)

Thanks

adding more capacitor just like in the tutorial fixed this problem.
