Hello, I have problem and I hope you can help me.
I have 3 sensor nodes. every node has an IMU sensor and nRF52840 microcontroller. These nodes send the IMU data to the central nRF52840 dongle via BLE. If the nodes have the same services and characteristics, how do I know which device is the data from? I also think it's not logical if I have a separate service and charachteristic for each node. I'm afraid that because of the same services I will lose the data.
Note: I have no previous experience with Ble but I am trying to understand it.
Best regards
Saad Debo
