nRF52832 s132 SDK15 - Scan not working with ble_connectivity over uart

Question

Hi, 
 I am trying to build the ble_connectivity code "ble_connectivity/pca10040/ser_s132_uart" to test the serialization part. The scan is not working. I am using PCA10040 board(same board is working fine with other ble application) to check the BLE connectivity over uart using serialization. 
 I didn't see anything apart from this call nrf_sdh_enable_request(). Do we need to do anything explicitly to enable BLE and soft-device? Am I missing anything here? 
 If so, why is this example not included this part? 
 My exception is that, I should be able to receive scan results , If I (1) connect PCA10040 to host over uart (2) flash the "ble_connectivity_s132_uart_pca10040.hex" and (3) Run my serializer application my embedded host. Correct me if my understanding is wrong. 
 I am using nRF5_SDK_15.0.0_a53641a, armgcc, PCA10040 board, s132 SD, Ubuntu16.04 as build environment and serializer is running on ARM based target with ubuntu.

Hello Govind, 
 Stian is out of office. 
 
 May I suggest that you try to run one of the simpler examples from SDK15 in serialization, just to find the source of the issue. 
 If you have two DKs, you can try to program one with the ble_connectivity firmware and the softdevice s132, and the other with e.g. 
 SDK15\examples\ble_peripheral\ble_app_hrs\pca10040\ser_s132_uart 
 And connect it like explained here . 
 If that works, you know that you have a setup that works. 
 
 Then you can try to run the SDK\examples\ble_central\ble_app_hrs_c\ser_s132_uart and see if that also runs fine, still using a DK as the application chip. If it does, proceed to run these projects from your embedded host. Does that work? 
 
 Best regards,
