I want to submit a service to minissdpd so that minissdpd advertises my service on my LAN.

I'm assuming I must use "request type 4 = submit service". Correct?

testminissdpd.c uses this command: 'char command4[] = "\x04\x00test:test:test";'
Is that the command I should use to submit a service? Is the ":" the separator ... ?

If so, in what format? Looking at other existing devices/messages, my first guess would be

char command4[] = "\x04\x00http://192.168.2.222:22222/IGD.xml:urn:dslforum-org:device:WANConnectionDevice:1:uuid:11111111-405a-3721-e8b8-20e882bf0aa1::urn:dslforum-org:device:WANConnectionDevice:1" ;

... but because there are multiple :'s I can't imagine this works. And indeed it does not work: it does not show up in the list reported my testminisspd

I think the answer is in the documentation, but I don't understand it:

request type 4 = submit service
1st byte = 4
(k,n) bytes : length and string "ST" (service type)
(k,n) bytes : length and string "USN"
(k,n) bytes : length and string "Server"
(k,n) bytes : length and string "Location"

I would appreciate to know the correct format for command4[].

FWIW I tried this format too, but doesn't work either.

char command4[] = "\x04\x00uuid:44444444-b051-11db-88f8-0060085db3f6::upnp:rootdevice" ;

FWIW 2

I tried to understand

http://miniupnp.free.fr/minissdpd.html

UPnP Device submit (request type 4)
These "request" type is used by UPnP devices that declare themselves and their services that way. The first byte is 4 and is followed by four Strings :

Service/device type
USN
Server string (as found in SSDP packets)
Location
There is no response.

and

https://github.com/miniupnp/miniupnp/tree/master/minissdpd

request type 4 = submit service
1st byte = 4
(k,n) bytes : length and string "ST" (service type)
(k,n) bytes : length and string "USN"
(k,n) bytes : length and string "Server"
(k,n) bytes : length and string "Location"
No answer

... but no luck

Further tries:

char command4[] = "\x04\x05PQRST\x05PQRST\x05PQRST\x05PQRST" ;
char command4[] = "\x04\x00\x05PQRST\x05PQRST\x05PQRST\x05PQRST" ;

... but no luck.

Help appreciated.
