spi_master_send_recv in an ISR

I am calling the spi_master_send_recv in a ISR from a GPIO using app_gpiote.c It causes a hardfault on APP_ERROR_CHECK(sd_nvic_DisableIRQ(p_spi_instance->irq_type)); Otherswise spi_master_send_recv works well when using the function from e.g. main(). Any hint...

most probably because your SPI interrupt priority is more than SVC priority and it will create a hardfault. SVC in softdevice is set to priority 2.
