ble heart rate monitor device connects but no data

Hello,

Apologies as I'm very new to C and I may be missing something obvious. I have an actual ble Heart Rate device which I wish to connect to my pca10028 (nrf51422_xxAC.

I am using the example code from the following path.

C:\nordic\examples\ble_central\ble_apps_hrs_c\pca10028\s130\arm5_no_packs\ble_apps_hrs_c_s130_pca10028uvprojx

I've added the necessary files to get SEGGER_RTT_printf to send data to J-Link so I know where the program has execute. It appears the device connects to hrt successfully as it stops advertising.

This line in code fires suggesting it's found the device:

   if(extracted_uuid == TARGET_UUID)
                    {	SEGGER_RTT_printf(0,"uuids match %d",TARGET_UUID);

and this line executes to suggest it had bonded

  // Initiate bonding.
            err_code = dm_security_setup_req(&m_dm_device_handle);
            APP_ERROR_CHECK(err_code);
						
            m_peer_count++;

            if (m_peer_count < MAX_PEER_COUNT)
            {
                scan_start();
            }
            APPL_LOG("[APPL]: << DM_EVT_CONNECTION\r\n");
						SEGGER_RTT_printf(0,"bonded %d", err_code);

But the Heart Rate Collector Handler or Battery Level Collector Handler never fire. So the last output I get on j-link is "bonded0"

Any help would be greatly appreciated.

UPDATE: I've replaced all logging information with SEGGER_RTT and this is the output. Disconnection happens after a minute or so
