Hi Trump,

It seems that you did not use the examples\peripheral\spis codes to handle the interrupt? Is there any reason for that? Did you make the spis sample work?

If you are new to BLE, I have some very good tutorials for you to get start:

Bluetooth low energy Advertising, a beginner's tutorial - Bluetooth low energy - nRF5 SDK guides - Nordic DevZone (nordicsemi.com)

(+) Bluetooth low energy Services, a beginner's tutorial - Bluetooth low energy - nRF5 SDK guides - Nordic DevZone (nordicsemi.com)

(+) Bluetooth low energy Characteristics, a beginner's tutorial - Bluetooth low energy - nRF5 SDK guides - Nordic DevZone (nordicsemi.com)

The last tutorial provides one solution which is almost close to your need, you just need to replace the timer with spi slave. It uses a timer to trigger MCU temperature updates. The temperature updating codes are inside the timer interrupt handler. What you need to do is to replace the configuration, interrupt functions of the timer with spis in the examples\peripheral\spis.
I have adapted the code for nRF5_SDK_17.0.2, just share it here with you for your reference. It also provides solutions for the last two challenges.

Please provide more detail if you need further help.

Best regards,

Charlie

I tried as you suggested, but I still don't understand。

Still can't produce interrupt, go executing afore-mentioned function

I suggest you start with learning the following two examples and replace UART with SPI slave.

examples\ble_peripheral\ble_app_uart

examples\peripheral\spis

I have a question about SPI slave communication.SPI slave can not receive data and generate interrupt under Bluetooth protocol stack。I don't know how to transplant SPI slave device with Bluetooth protocol stack

Hi liu123,

Some suggestions to you:

1. Try to use English so other people can understand your questions and offer help. If it is challenging for you, using translation tools may be a good start.

2. A detailed question description could be very helpful for us to understand your problem. Can you provide more information like what you did to add the SPI driver and what kind of error reports did you see?

3. Please search the keywords "SPI BLE". You will find several related discussions which may give you inspiration, for example, SPI nrf52832.

We also have local sales and FAE can give you direct help. You can connect them through this page.

Best regards,

Charlie
