As Nick says, Bluetooth Classic is not the best solution for this. It could be done with BLE but would need true BLE not the cheap UART modules like the HM-10.
Have a look at MQTT and the ESP8266. There is already a lot done for this and you will probably be able to find ready made solutions. The only down side is that MQTT requires a server but this can be something like a pi rather than a full desktop.
