[NRF51822] SPI data loss during BTLE connection

[Jeffery]

Hi

SPI master is 3rd party MCU. SPI slave is nRF51822. If MCU sends a bunch of data to nRF51822 via SPI, at the same time, BTLE host like celluar phone try to connect nRF51822, is it possible to lost SPI data during the BTLE connection? If yes, did you have any suggestion to keep it from? Thanks.

Hi Jerrery,

Have you experienced any issue with SPI slave and BLE stack ?

The data rate of SPIS slave is limited at maximum 2Mbps and this will allow no collision between the radio and SPIS on accessing RAM using DMA .
