I have a digital scale and one of this kind of bluetooth adapter.
They are connected by RS232. And the bluetooth adapter can be manipulated by AT commands.
I've found this project on Github. But this is just for Wifi module, I guess. I need to input host name and port number.
But I need to connect bluetooth module.
I'd like to implement this kind of feature. But I only needs the value of weight from the digital scale. The user will not type anything but send AT commands under the hood on the app and then get the weight value.
If there is alternative way, please let me know!
