Les trames arrivent comme ceci

!AIVDM,1,1,,B,1:182j003R0K3T4H>PdLsbI20
HC8,0*51
!AIVDM,1,1,
,A,13ccWT001s0Hss4HWKicLa<2080d,0*08
!AIVDM,1,1,,A,13chtv003
$PNMLS,30,20,3*52
!AIVDM,1,1,,A,1:182j003R0K2
$PNMLS,31,20,3*53
F04Sd,0*1E
$PNMLS,28,21,3*5A
2f:H>agttbHN0@8Q,0*05

ce que je souhaiterai c'est de passer de

!AIVDM,1,1,,B,1:182j003R0K3T4H>PdLsbI20
HC8,0*51

à

!AIVDM,1,1,,B,1:182j003R0K3T4H>PdLsbI20HC8,0*51

.
Tout en ignorant les trames commencant par"$PNMLS"
Voici mon resultat

$PNMLS,33,19,3*5B
$PNMLS,34,19,3*5C
!AIVDM,1,1,,A,1:182j0vCQ0Jlp@HA5p=1JLN00S<,0*69

je n'arrive pas a virer "$PNMLS"
