Application timer in Secure bootloader.

[Prajapati]

Dear team,

Device - nRF52832
SDK - nRF_SDK_15.0.0
Softdevice - s132_nrf_6.0.0
IDE - Segger embedded studio

My application needs to toggle one gpio pin using app timer in secure bootloader code. I tried to create app timer in bootloader code but advertisement stops. I can't understand the reason behind that.

Here is my main function as below.

}

Please give me some possible solutions on that.
