about ANCS in SDK 9.0 ,the problem of SPI crash

[luoyejie]

Hi:

I am using the ANCS from SDK9.0 ,SoftDevice8.0 and iOS8.1.3.

Every time when I run ANCS, SPI will often crash.and error codes is:NRF_ERROR_BUSY.

Don't know if you have encountered the same problem, personal think is ANCS with SPI caused by resource preemption, but now there is no way to solve, hope to get your help.

Thank you.

Do you get an error busy when you calling spi_master_send_recv? Then why don't you try to call it again, may be like below

while (spi_master_send_recv(spi_master_hw_instance, p_tx_data, len, p_rx_data, len) == NRF_ERROR_BUSY);
