SPI slave with nRF52 BLE

[Ywel150]

HI I am working with nRF52 DK softdevice s132 sdk v11.1

I tried out the SPI master and slave examples and they work fine (I can transfer and receive data) I have been trying to add SPI slave to the heart rate example provided in the sdk and have been working on it for a whole day.

The master example by itself still receive data from the SPI slave I added on the heart rate example, but the SPI slave doesn't receive any data from the master

I double checked all PIN configs and feels like its some small mistake somewhere in the code but just can't seem to figure it out.

I have attached my main.c here. Can someone please have a look at it. Thanks in advance.

Hi,

I just tested your main.c code together with the SPI master example in the SDK. It worked just fine. Your code sent “1234567”, and received “Nordic” from the SPI master. Are you testing this with a PC-terminal? It could be an issue with the terminal? try to disable/enable the terminal, and turn off/on the deivce.

Hi Thanks for the response I tested it with J-link RTT. The master side did print but not the slave side, didn't even print the SPIS_init where i did "NRF_LOG_PRINTF("SPIS example\n");" I will do what you suggested and let you know. Thanks.
