HttpsClient example '400 Bad Request' #440

Open Conwon99 opened 3 years ago

Conwon99 commented 3 years ago

What are you working with?

Development Kit: ESP32-Wrover-Kit Kit version; v1.3 Module or chip used: ESP32-WROVER-B Modem: SIM800L TinyGSM version: Don't know how to check (Must be latest)

Code: https://gist.github.com/Conwon99/bdd4a094342adee5c54443412a757a44

Scenario, steps to reproduce

I'm fundamentally attempting to get https to work with TinyGSM - i'm using the HttpsClient example which uses a GET request to retrieve the TINYGSM logo. I connect to the server fine but I get the 400 bad request response. This would lead me to believe it is a formatting error but i'm using the example code so I don't know whats going on. I am able to get the logo using the HTTPClient example which means theres something wrong with https specifically, but I don't know what. Any help would be really appreciated!

Sorry this is late, but the SIM800's SSL functionality is pretty hit-or-miss.
