Hi perry,
I successfully tried this before, but I wasn't happy that sent sms are not visible in the sms app and also I can't see the previous sms on my PC. So I'm trying to build a separate KaiOS app that mediates between the Mobile Messaging API, which perfectly integrates with the system's sms app, and a PC/Server. So my question aims on sending messages from inside an app
over USB or Network. I think having a local webserver and starting a Websockets connection from the app will be the best solution, since I didn't find anything considering USB.
