Scaning more than one devices


I am new to DUO Redbear,
I have four DUO boards. I want to use 3 as beacon and 1 as central to find location of others using RSSI value. I have find an arduino code to get RSSI value by scaning commands. But how it will possible to scan rssi value of all three other board at same time?
If anyone have idea please tell me. I don’t want to connect these devices to central. i will just scan for these devices and get thier RSSI value. Please tell me any method to scan all three devices at same time
Thank You


Hi @faiz07,

Please take a look at the example for the Central device and this example for iBeacon device.

Best regards,
