no signals from sx1276mb1mas on stm32L476RG

Hello all, I'm using the lora shield SX1276MB1MAS (on 868Mhz) on the nucleo STM32L476RG connected to my laptop's USB port. With the help of mbed's online compiler I loaded binary from Lorawan-demo-76 example to the nucleo. I couldn't see any signals (join request, or data) being emitted from the device. I use a spectrum analyzer to verify this. Would there be any issues with the inadequate power supply for the shield to operate correctly ? I guess the USB port from the laptop should be ok but i'm bit skeptical when using the board with shield mounted on it. any suggestions to identify the problem?

thanks, Arun
