How to use 100 BLE bluetooth at the same time


We bought 100 RedBear BLE bluetooth, and our 100 students will use them at the same time. How can they know which bluetooth they should connect because there will be 100 bluetooth to be connected when they scan.


Hi there,

Look at this example, you can change the line ble.setDeviceName((const uint8_t *)"Simple Chat"); with other name for each student, do you think it will work for you? It will broadcast with the name you change and use iOS LightBlue App to see, you may need to connect it one time to see the new name because iOS will cache it.
