Hello, firstly thank you for your sharing this repo. It worked with sending manuel datas to firebase.
But my problem is, I'm using geolocation api and sending data to firebase, theese both service uses https so I couldn't connect with same Lilygo Sim800l. Tried your method, and actually its working witn defined datas. But when I tried to done something with variables , it returns 403 forbidden.
I'm trying to post json datas to my server, and my server makes request for me, after response, sending response to firebase. Its working wth postman and reqbin. It never fails. But with sim800l, it always returns 403 forbidden. Do you have any advice?
