Hello everyone, I'm trying to connect my Arduino uno r4 to a MIT app. I'm fairly new to both platforms. I can't seem to get my MIT app to connect. My phone will connect to the Arduino just not the app and it will give me an 507 error when I try and connect though my app. This Arduino uses a BLE. However I'm not sure if I'm referencing my uuid correctly. I was wondering if this was the correct MIT code to connect to Arduino? Any help would be much appreciated. Thanks!
Most people use the BLE extension.
