I'm starting a new project in my Electrical Engineering degree at my university and I need help.
Overall, my project is about a mini robot that collects data and sends it (via wireless communication) to the main control unit from a distance of about 100 meters.
It's main specification demands are: small, lightweight, use an STM32 microcontroller for the mini robot and it is preferred that the data that is sent from the mini robot to the main control unit will be secure as possible.
Here is where I need help. I have 2 options for the wireless communication: Bluetooth and RF.
I know that RF has a larger distance communication capabilities, but I'm afraid that the RF module weight will be heavier than the Bluetooth module.
My questions are:
- What are the main differences between RF communication and Bluetooth communication (weight, dimensions, power demands, communication distance, data transfer speed and secure data transfer)?
- What communication method do you recommend me to use (with respect to my project demands)? RF or Bluetooth?
Thank you for your help.
