BlueNRG LPS taking more time in receiving data over SPI



I have connected Bluenrg LPS eval board (network coprocessor mode) with STM32L476 Nucleo board and both are connected via jumper wires.

I'm transferring 30 bytes in a single packet from STM32 nucelo to Bluenrg LPS module what I have seen is, once stm32 sent 1 byte from SPI it waits for interrupt from bluenrg LPS and this wait time is so longer sometime that it gets timed out or timer gets expired(in context of code). And this behaviour happens with almost all packets.

I tried the sensorDemo example code (from bluenrg LP DK), sending same amount of data is taking lot of time on this as well.


Can someone help me in localizing the problem, am I missing any parameter configuration or is it just because of jumper wire?
