my nordic ble device is not getting advertised or discoverd in my phone after running secure ble

Hello,

There can be a number of reasons for the device to not be discoverable, so we need more information to be able help find the problem. Here are some follow up questions that comes to mind:

1. What SDK version are you using?

2. Are you using a custom board or a nordic dev board.

3. Do you have any debug logs

4. Have you tried debugging the code to see if it crashes/get stuck somewhere? In that case, can you post a screenshot to show us what you see?

5. Are you able to discover the board with other BLE examples

 im getting this error while debugging ble buttonless 

[Vidar Berg]

The buttonless template app requires a bootloader to be present in order to run, can you please try another example to confirm normal BLE examples run ok on your board? For instance, the ble_app_blinky example (\ble_peripheral\ble_app_blinky\pca10040e).

ble app blinky one works but while debugging after selecting files like main.c,nrfx clock and ses startup etc.. its showing overlap and cant download files.
