And just when you think you’ve caught up with the espressif8266 arduino releases… they go and release 2.6.2 10 hours later! :laughing:

Look forward to trying out 2.6.x … seems like there’s some good stuff happening there.

2.3.1 is out! :slight_smile:

Well snap! :smiley:

Here’s hoping it lasts a little longer! :laughing: Thanks Ivan :wink:

Tried 2.3.0 and 2.3.1 but it doesn’t compile, problems with WiFiClientSecure

2.2.3 and earlier compile as it should but 2.3.0 and 2.3.1 complain about:

error: ‘using ESP8266WebServerSecure = class esp8266webserver::ESP8266WebServerTemplateBearSSL::WiFiServerSecure’ has no member named ‘setBufferSizes’

‘using ESP8266WebServerSecure = class esp8266webserver::ESP8266WebServerTemplateBearSSL::WiFiServerSecure’ has no member named ‘setRSACert’

Should I change something else? Again, it compiles under 2.2.3 and lower

framework = arduino
platform = espressif8266@2.3.1 // 2.2.3 = ok
board = d1_mini

Without seeing a MVCE / reproducible code example it’s hard to tell. Do the examples provided by the esp8266 Arduino board support package work for you? As you can see, with platform = espressif8266@2.3.1 both of these example sketches work fine.

Example code using setRSACert.

Thanks, I see there have been some changes:

server.setBufferSizes
server.setRSACert

have become

server.getServer().setBufferSizes
server.getServer().setRSACert

Now it is compiling

edit… after compiling and testing:

I gained almost 2kb free heap with the new 2.3.1 Very good !!!

Regards,
Henk

Yeah, I saw there was mention of…

Changes since 2.4.2 (to 2.5.0)
Breaking change
SSL/TLS API (BearSSL)

… in the release notes, but that would mean espressif8266@>2.0.0 would have those changes… so I don’t know what was the cause of that change to the API.

Anyway, obviously it’s working for you now! :slight_smile:
