I recently starting playing around with a few esp8266-01s and tried to use the SSDP libraries to work with Smarthings discovery:
https://docs.smartthings.com/en/latest/cloud-and-lan-connected-device-types-developers-guide/building-lan-connected-device-types/building-the-service-manager.html
on the docs there are example grovy files that do simple service discovery, i was not able to get SSDP to work correctly, though i was able to find some other projects that did (python fauxmo works for alexa, but with modifications i was able to make it work for custom devices in ST).
after digging to figure out why the python code was working and the ESP SSDP lib was not i noticed there is a string comparison in the grovy file and it was failing to match the udn with the original usn device id. The ST groovy code could be changed to remedy this problem but i wonder if it should be fixed here, because so many other examples of SSDP discovery take care in ensuring the usn and udn match exactly.
___________
Summary, I think the USN and UDN values should match exactly. This will fix issues, allowing for much easier integration with smart hubs that need the device ids to match. Allowing me to use these libraries and not need to roll a custom SSDP handler.
Content length provides context into the size of the upload, it's not
the exact form body size it's off by the request header info, but it was
already parsed by the library and provides little to no additional
overhead to pass on for use in request handlers.
Currently post args are only available at the end of upload but they are already listed - this PR just expose them with minimal changes
It also set a define for post args array size originaly set to 32
Many objects now expect a WiFiClient* object to be passed to them and
potentially re-used multiple times (HTTPClient, others). Clearing the
authentication options on a ::stop means they can never reconnect.
Remove the option clearing in ::stop

modes to the encryption options.
* Enable the aes_ccm initialization in client/server
* Initial attempt
* Working code with second stack thunking
* Remove #ifdefs in .S file, not needed.
* Clean up thunks and remove separate stack flag
* Fix PIO assembler errors
* Remove #ifdef code changes, ensure same code as PC
Remove "#ifdef ESP8266;...;#else;...;#endif" brackets in BearSSL to

* Move to latest BearSSL w/EC progmem savings
* Merge with master
* Add br_thunk_* calls to do ref counting, painting
Add reference counting br_thunk_add/del_ref() to replace stack handling code
in the class.
Add in stack painting and max usage calculation.
* Add in postmortem stack dump hooks
When a crash occurs while in the second stack, dump the BSSL stack and
then also the stack that it was called from (either cont or sys).
* Update stack dump to match decoder expectations
* Move thunk to code core for linkiage
The thunk code needs to be visible to the core routines, so move it to the
cores/esp8266 directory. Probably need to refactor the stack setup and the
bearssl portion to avoid dependency on bearssl libs in cores/esp8266
* Add 2nd stack dump utility routine
* Refactor once more, update stack size, add stress
Make stack_thunks generic, remove bearssl include inside of cores/esp8266.
Allocate the stack on a WiFiServerSecure object creation to avoid
fragmentation since we will need to allocate the stack to do any
connected work, anyway.
A stress test is now included which checks the total BearSSL second
stack usage for a variety of TLS handshake and certificate options
from badssl.org.
* Update to latest to-thunks branch
* Add BearSSL device test using stack stress
Run a series of SSL connection and transmission tests that stress
BearSSL and its stack usage to the device tests.
Modify device tests to include a possible SPIFFS generation and
upload when a make_spiffs.py file is present in a test directory.
* Use bearssl/master branch, not /to-thunks branch
Update to use the merged master branch of bearssl. Should have no code
changes.
BearSSLX509List, BearSSLSession, BearSSLPublicKey, and BearSSLPrivateKey
were all in the global namespace and not in the BearSSL:: one, due to an
oversight when they were originally created. Move them to the proper
namespace with the following mapping:
BearSSLX509List => BearSSL::X509List
BearSSLSession => BearSSL::Session
BearSSLPublicKey => BearSSL::PublicKey
BearSSLPrivateKey => BearSSL::PrivateKey

skip the second POST as end() has different semantics and nulls the client pointer
use bearssl in ssl tests

calls and is safe from either SYS or CONT contexts.
Fixes#5237.

key_end_pos--;
dont count down here, it will cut of every key by -1 ("save" will be "sav") (substring (end = up to, but not including, so no need to -1)
Parsing cpp L329
arg.value = urlDecode(data.substring(equal_index + 1, next_index - 1));
=> -1 is too less for substring (substring (end = up to, but not including, so no need to -1)

Make HTTPClient take a WiFiClient parameter, allowing you to pass in a
simple HTTP WiFiClient or a BearSSL or axTLS WiFiClientSecure with
any desired verification options. Deprecate the older, TLSTraits methods.
Add basic HttpsClient example.
Add optional LED feedback to the Update class
This speeds up the ESP8266WebServer::streamFile more than 3 times. Tested on streaming the 800+ Kb file from SD (FAT32), average time without a fix was 9000 ms, with the fix is 2600 ms (maximal possible SPI speed used), which is as fast as streaming the same file from internal SPIFFS. Hardware: WeMos D1 mini.
If the server returns several headers of the same key (e.g Set-Cookie) only the last one is returned, causing issues in communicating with some servers where cookies are required.
This change concatenates the headers of the same key separated by "," to alleviate this issue.
Print a warning when in debug mode when a BearSSL connection tries to
connect without having any defined authentication methods, since it will
fail.
Completely remove the empty axTLS compatibilty method
"::verify(char *fp, char *name)" because it can't be done w/BearSSL w/o
user code changes, and always failed. Better to have a compile failure
when we know at compile time the app won't do what is expected.
Completes the changes started by @d-a-v in PR #4833
Add a method allowing a user to send in a character string for the
fingerprint, like axTLS supported.
Implements part of PR #4833 from @d-a-v with changes requested in
discussion.
The BearSSL second stack, once allocated, was never deallocated. The
reference count of the stack pointer never hit 0 due to the initial
creation counting as one. Now, check to see if there is only one use_count
and if so then delete the stack.
SSL Sessions enable most of the SSL handshake to be skipped when both
client and server agree to use them. Add a BearSSLSession class and
an optional setting to the SSL client to enable this.
Note that SSL sessions are unrelated to HTTP sessions. They are
ephemeral and only relate to the SSL parameters, not anything at
the HTTP protocol level.
The cipher list count/pointer was cleared separately in the three
constructors available. Move this reset to _clear() to reduce code
duplication and keep the semantics.
Pull in latest BearSSL head (0.6 + minor additions) release and add AES_CCM
modes to the encryption options. Enable the aes_ccm initialization in client/server
The EC mul20 and square20 code was identical in two different files,
but because these copies were static, we ended up with an extra 6k of
duplicated code. Updated BearSSL to make them shared, saving 6KB.
