Hello,
Into Tag definitions, you said :
- FT_BOOLEAN, 40 bits = 5 bytes
- mask goes to 0x0800 and so on which is 2 bytes long (and so on)
Into proto_tree_add_boolean calls, you said : length = 1 byte
-> incoherent
-> proto_tree_add_boolean could not apply mask > 0x00ff
So try :
- proto_tree_add_boolean calls with length = 5 bytes (NB: not sure
value above 4 is accepted, must check)
- do not increment offset
