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?

Wow, now that's a question.
Hyperterminal is a program that makes your PC act like one of those 'dumb terminals' you would see in old movies and TV shows from the 70's. It connects your screen and keyboard to a communications port, commonly a Com port (RS232) or a USB port.
Any ASCII character that is received on the port is displayed on your screen and any key you press is sent as an ASCII character down the port.
Since you said the remote Bluetooth was connected to an Axon it is the Axon processor that is reading the voltage on the photoresistor from its ADC and converting the binary ADC value into ASCII characters then sending them out a serial port to the Bluetooth module.
I don't know much about Bluetooth but believe that any two Bluetooth modules will automatically connect. Hope some can give you details on this.

ever tried connecting phones via blue tooth?? u turn it on tell it to sent it scans for devices and click the right wun i assume the same applies here aby blue tooth dongle plug it in and open it wif computer and fingas crossed it will connect
