Wireless Arduino connection with a computer and another Arduino

Hi all,

I would like to send wirelessly some data from my computer to two arduino to control motors. If the ID of the motor I want to control is not connected to the first arduino, I want this arduino to pass the command wirelessly to another arduino. For commodity reason, I just want the computer to be bluetooth connected to one arduino. The command are very simple (few bytes each seconds)

I plan to use 2 arduino nano 33 BLE for that. Let's call them Arduino1 and Arduino2.

  1. I bluetooth connect my computer with Arduino1 (with python)
  2. Arduino 1 and Arduino2 bluetooth connect eachother automatically
  3. At each command received by Arduino1 from the computer it checks if the command is for itself. If not, it transferts the command to Arduino2.

Here are the questions:

  1. Can you really have simultaneous connection with arduino nano BLE ? I read that BLE enable multiple concurrent connections, that is why I think this solution might work.
  2. Is it possible to wirelessly connect the computer with Arduino1 with a non BLE bluetooth connection ?
  3. Can you imagine another setup to make this project working ?

ad 1) As slave it's 1, IIRC when it's master the limit is 4. But then there is BTLE mesh protocol, and that's most likely what you want to use. Don't know if the limit is still 4 devices then.
ad 2) Why not? e.g. serial would work.
ad 3) use ESP32 - way easier
