I bought a Heart Rate Sensor from the market and trying to read data using ble_app_hrs_c example on nrf52832.

So I bought a BLE Heart Rate Sensor (chest strap) from market.
I am able to read data using the nRF Connect Android App.



Now I am trying to read the Heart rate data using nRF52832 and ble_app_hrs_c_pca10040_s132 example.
I am getting the errors mentioned below.

<info> app_timer: RTC: initialized.
<info> app: Heart Rate collector example started.
<info> app: Starting scan.
<info> app: Connected.
<info> app: GATT ATT MTU on connection 0x0 changed to 23.
<info> app: Data length for connection 0x0 updated to 27.
<info> peer_manager_handler: Connection security failed: role: Central, conn_handle: 0x0, procedure: Bonding, error: 133
<info> app: BLE_GAP_EVT_AUTH_STATUS: status=0x85 bond=0x0 lv4: 0 kdist_own:0x0 kdist_peer:0x0
<info> app: Disconnected, reason 0x13.
<info> app: Starting scan.
<info> app: Connected.

what should I do to resolve this problem?

It's likely because the central example is setup to support bonding, and peer manager will disconnect if bonding fails. I can try to modify the central example to ignore bonding if you are not able to solve it yourself.
