Is it possible to use either Grove - BLE (CC2540) or Grove - BLE (CSR Dual Mode chip) to detect other BLE devices which are configured to transmit iBeacon formatted data packets and read this information - typically provides UUID, Major, Minor, RSSI values etc.
Hello，
Here is official documentation of iBeacon of HM13 module, I hope it can help.
