How to read Beacon UUID, RSSI, major , minor and Tx power by using NRF52840 DK?

[mayuri]

HI All,

i m new to this technologies.Now m using NRF52840 DK and sdk as nrf15.2..we have developing the nrf52840 as a beacon scanner to scan the ibeacon details like rssi, uuid, txpower,majoe and minor..how to scan beacon value from nrf15,2 sdk? please help me out.thanks in advance

Hi,

Unfortunately, we do not have an example for scanning beacons. You can use any of the central examples from the SDK, but I suggest you to use the UART central example as a starting point. In your central application, you will get a BLE_GAP_EVT_ADV_REPORT event in the BLE event handler whenever you get an advertisement packet. You will need to extract the data(RSSI, UUID, tx power, major and minor) from the manufacturer spceific data.

Are you using the beacon example from our SDK as your iBeacon? 

[mayuri]

yes

Have you added the TX power inside the advertising packet? Tx power is not included in our beacon example by default. See here.

hi 

i added 

sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_SCAN_INIT, BLE_GAP_TX_POWER_ROLE_ADV, 4);

in ble_app_beecon .

i can read uuid value from my reader nrf52840

Hello Mayuri, 

Are you scanning for the beacon kept in the surrounding and trying to read its parameters ? and the above snippet that you have added is for which code ? UART or Beacon ?
