I just saw a video on youtube where a guy connects a bluethooh component to Axon MCU. He then connects a Bluetooth dongle to the PC. He then presses a button called [Call] in hyper terminal (software) to connect via bluetooth, and starts receiving data from a photo resistor also connected to Axon. What i do not understand here is how did the bluetooth devices connect? Is there any settings? Can we use any bluetooth/wireless module on Axon and any dongle on the PC?
How did the photo resister component send the data via bluetooth (i mean how to tell the components like sensors, photoresistors, etc to send the data via bluetooth and not via cable for example?
Is hyper terminal a program that is used to receive data from MCUs. What if you have many components sending data to PC, how can you say which is coming from which component?
