The only way to communicate with Grove - Serial Bluetooth v3.0 is to send AT commands. So what is the best way to send from a (Arduino+Grove Temperature & Humidity Sensor + Grove Serial Bluetooth) to another (Arduino + Grove Serial Bluetooth). I was able to pair bluetooths, but could not figure out how send meaningful data (for example temperature = 18C as json) to another Arduino over bluetooth with these modules. The available tutorials only cover pairing which is literally not useful if you are not able to send any data.
