ios advertising 1 service despite me specifying 2 service uuid's , services, don't errors, , add service error function called twice, both times without error, code for uuids in advertisinguuids { self.mainservicesarray.append(cbmutableservice(type: uuids, primary: true)) } services in mainservicesarray { self.peripheralmanager.addservice(services) } self.peripheralmanager.startadvertising([cbadvertisementdataserviceuuidskey: [mainservicesarray[0].uuid,mainservicesarray[1].uuid]]) the rest of code runs fine, in example i've put there advertise first of 2 services, order doesn't matter first 1 advertised second not, uuid's valid services won't advertise them both, i'm sure simple i'm stuck. thanks the reason second uuid doesn't fit in advertising packet. the second service still not shown when scan connected device though, thats problem.

when using hexl-mode in emacs view binary file, there way of copying , pasting section file? i have tried standard c-spc , select region, m-w but pasting new file treats whole thing normal text, i.e. text file looks lots of these: 000159a0: 6e00 1295 00e0 3400 0a51 0942 0701 1295 n.....4..q.b.... i.e. making literal copy of text, not copying binary data representing what want copy section, paste new file such binary representation of section in other words want able generate new binary files parts of original binary file using hexl-mode viewing original binary file hope makes sense.. that sounds cool feature, unforuntately hexl-mode doesn't that. next best thing can clip file head , tail , example yank file.txt 000002a0 00000340, you'd run head file.txt -c $((0x00000340)) | tail -c +$((0x000002a0)) | xclip -sel c

what recommended place storing key-value pairs in dns request? i'm designing system dns requests traverse multiple hops. hops may need append key-value pairs traversing dns request. i thought adding txt record questions section looks no data can set on txt record when present in questions section (i used dnsjava library generate dns request). thought using opt record. what best practice? thanks, mickael there no recommended place store random information in dns query packet. can perhaps try stick in unused parts of opt rr (or add random rdata it) , hope nobody on way drop or corrupt it, there absolutely no guarantees whatsoever work. unless, of course, control software involved, in case you're free redefine dns wire format see fit (just don't expect interoperate internet). also question smells lot "a-b-question". you're trying achieve?
