SPI does not give out the INT when radio working??

[jimlin]

Hi all, I met one strange thing on SPI interrupt: when 51822 advertising, the SPI write and read works well; But, when CONNECTED, with BLE_GAP_EVT_CONNECTED event occured, the SPI does NOT give out the interrupt, spi_master_event_handler() not trig. The SPI IRQ priority is LOW and make this result happen. While set to HIGH, it works well, too. So, I want to know, whether the radio hold on the SPI interrupt so that app could not get it correct? Any influence with this priority change from LOW to HIGH?

Thanks.

Can you tell us which device, SDK and softdevice you are using.

51822, G2, SD7.0 and SDK 6.0

I am not aware of any interrupts being completely missed in the cases like yours. Can you move to latest SDK8.0 and latest SD8 and see if this still problem still exists?

I will later try to see if old SD or SDK have the problem you mentioned, but then that will not be very soon.
