BLE signal range measurement

Using Arduino Programming Questions
1

Hi everybody,

I would like to use 4 differents bluetooth modules (HC-05 or Hc-06 or else)

  • first module A/ arduino A, the main one
  • second B / arduino B
  • third C / arduino C
  • fourth D / arduino D

Module A / arduino A never moves and stays on a table for exemple
B, C and D are kind of satellits of A

the goal of thr project is a kind of tracker:

The module A, the main one, reads each seconds the power signal of the modules B,C and D.
If B, or C, or D is too far away from A, than Arduino A blink.

so the program is something like :

  • getting the ssid value of each B, C, D each seconds
  • arduino A compare values

Questions :

i tried to write the programm, read a lot of topics but i'm afraid it's too complicated for me... have you got an idea of a simple one?

If only the power range is read, can i just put a battery on B, C and D without connecting them with an arduino?

Thank you a lot, i hope i was clear :))

The module A, the main one, reads each seconds the power signal of the modules B,C and D.
If B, or C, or D is too far away from A, than Arduino A blink.

i think you're trying to determine if "B", "C" or "D" is farther than some distance determined by "A" because its signal is no longer detected. is this correct?

thank you for your answer.... yes you're right :slight_smile:

any idea?
