How can the HC-05 BT receive data or output from the lidar sensor when connected directly to each other (without Arduino) and how can we differentiate between the data given from the lidar sensor, as an example: how can the BT differentiate between whether the distance is 5 meters or 10 meters. Is it a matter of coding and programming or do we need an external device between them for such matter ?
Does this question relate to your other topic ?

My first question was slightly different because it was particularly including Arduino. I am basically creating a blind spot mirror system using 2 Lidar sensors with 2 BT devices ( HC-05 ) connected directly to them and one main Arduino inside the car with a 3rd BT device. My question here is regarding the 2 Lidar sensors and the 2 BT devices on the side mirrors. Can I connect the Lidar sensor directly to the BT device and if yes then how can each BT device differentiate between the data received from the Lidar distance-wise since the Lidar sensor will be measuring the distance of objects ? Is it a matter of coding or an external device is needed ?
The HC05 is essentially a serial pass through device. Does the LIDAR output UART asynchronous serial? It cannot do any processing on its own even if it could receive data from a LIDAR, which I doubt.
Post a data sheet for the LIDAR.
