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

Hi,
I am adding the 802.11k RRM capability Info which is a 5 Byte
data. This is what i added.
proto_item *ti;
proto_tree *sub_tree;
guint16 capability;
offset+=2;
capability = tvb_get_letohs(tvb, offset);
ti = proto_tree_add_uint_format (tree,
ff_rrm,tvb, offset, 5, capability,"RRM Capability Byte1: 0x%04X",
capability);
sub_tree = proto_item_add_subtree (ti,
ett_tag_rrm_capability);
/* Begin : First Byte*/
proto_tree_add_boolean (sub_tree, hf_tag_link_measurement, tvb,
offset, 1, capability);
proto_tree_add_boolean (sub_tree, hf_tag_neighbor_report_capability,
tvb, offset, 1, capability);
proto_tree_add_boolean (sub_tree,
hf_tag_parallel_measurement_capability, tvb, offset, 1, capability);
proto_tree_add_boolean (sub_tree,
hf_tag_repeated_measurement_capability, tvb, offset, 1, capability);
proto_tree_add_boolean (sub_tree, hf_tag_beacon_passive_capability,
tvb, offset, 1, capability);
proto_tree_add_boolean (sub_tree, hf_tag_beacon_active_capability,
tvb, offset, 1, capability);
proto_tree_add_boolean (sub_tree, hf_tag_beacon_table_capability, tvb,
offset, 1, capability);
proto_tree_add_boolean (sub_tree,
hf_tag_beacon_reporting_condition_capability, tvb, offset, 1, capability);
/*End : First Byte */
offset+=1;
/*Begin: Second Byte */
proto_tree_add_boolean (sub_tree, hf_tag_frame_measurement, tvb,
offset, 1, capability);
proto_tree_add_boolean (sub_tree, hf_tag_channel_load_capability, tvb,
offset, 1, capability);
proto_tree_add_boolean (sub_tree, hf_tag_noise_histogram_capability,
tvb, offset, 1, capability);
proto_tree_add_boolean (sub_tree,
hf_tag_statistics_measurement_capability, tvb, offset, 1, capability);
proto_tree_add_boolean (sub_tree, hf_tag_LCI_measurement_capability,
tvb, offset, 1, capability);
proto_tree_add_boolean (sub_tree, hf_tag_LCI_Azimuth_capability, tvb,
offset, 1, capability);
proto_tree_add_boolean (sub_tree, hf_tag_transmit_stream_capability,
tvb, offset, 1, capability);
proto_tree_add_boolean (sub_tree,
hf_tag_triggered_transmit_stream_capability, tvb, offset, 1, capability);
/* End: Second Byte */
and Tag definitions as
{"Link Measurement Capability",
"wlan_mgt.link.measurement",FT_BOOLEAN,
40,TFS(&cf_rrm_link_flags),0x0001, NULL, HFILL }} and hex values for
rest of the tags as 0x0002,0x0004,0x0008,0x0010,
0x0020,0x0040,0x0080,0x0100,0x0200, 0x0400,0x0800 and so on. But only
the first byte is getting displayed properly. The offset positions are
correct but it is not getting displayed. From 2nd byte onwards it is
diplaying blank dots only like this.
*.... .... .... .... .... .... .... .... .... .... = Frame Measurement
Capability: not implemented*
How to display this 40 bit data properly? Please suggest as i am stuck
with this.
Thanks,
Soumya
